The eight levels of taxonomy hierarchy (biological classification system): - CORRECT ANSWER Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species... [Show More] . What does the domain level consist of? - CORRECT ANSWER Archea, Eukarya, and Eubacteria. ***Eukarya consists of: animailia, fungi, plantae, and protista. *** Archea consists of: archeabacteria. ***Eubacteria consists of: eubacteria. Binomial nomenclature: - CORRECT ANSWER Used when classifying individual species, the Latin name of the genus and species is written in Italiacs with the genus name capitalized and the species not capitalized. Natural selection: - CORRECT ANSWER Occurs when some individuals of a species are better able to survive in their environment and reproduce than others; also known as "survival of the fittest". Genes: - CORRECT ANSWER Stretches of DNA on a chromosome that provide information for an organism's characteristics; are responsible for heredity. Alleles: - CORRECT ANSWER Different forms of genes in which some contain one or more mutations. Mutations: - CORRECT ANSWER Changes in the DNA that affect the way a gene functions. Adaptation: - CORRECT ANSWER A process through which mutations and combinations of alleles, some individuals of a species are better able to survive and adapt to the environment in which they live. ***Although adaptation is the end result, the process of natural selection produces it. Two strains of yeast are placed in a hot environment. Strain A has a mutation in a gene that results in an ability to tolerate and grow at the high temperature. Strain B does not have a mutation in the same gene and is unable to survive as well in the hot environment. The yeast strains are allowed to grow and reproduce for a time. After a number of generations, a sample is tested and only strain A is found. This is an example of what? - CORRECT ANSWER Natural selection. The action of natural selection is due to the presence of mutations in the DNA that are passed on from generation to generation. (True or False) - CORRECT ANSWER True. What is the function of nucleic acids? - CORRECT ANSWER To store and transmit hereditary information. What is a nucleic acid? - CORRECT ANSWER A chain of nucleotides that consists of a pentose, a phosphate group, and a nitrogenous base. Pentose: - CORRECT ANSWER A type of sugar. In nucleic acids it is either ribose or deoxyribose. Phosphate group: - CORRECT ANSWER A molecule in the backbone of DNA and RNA that links adjoining bases together. Nitrogenous base: - CORRECT ANSWER A molecule found in DNA and RNA that encodes the genetic information in cells. 5 types: adenine, cytosine, guanine, thymine, and uracil. ***Thymine is unique to DNA and Uracil is unique to RNA. The double helix: - CORRECT ANSWER The double helix is able to form because weak bonds are able to form between the hydrogen atoms and oxygen or nitrogen atoms between bases in the complementary strands of DNA. This weak bond is called a hydrogen bond because one partner in the bond will always be a hydrogen atom. ***In DNA adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). Purines: - CORRECT ANSWER In the DNA's double helix, adenine and guanine have two rings which are known as "purines". Pyrimidines: - CORRECT ANSWER In the DNA's double helix, thymine and cytosine have only one ring so are classified as "pyrimidines". ***In RNA, the pyrimidine base Uracil is used instead of thymine. RNA structure: - CORRECT ANSWER Exists as a single strand of nucleotides. The difference between RNA and DNA other than their structural differences is in RNA's pentose component where DNA (deoxyribose) has one less oxygen atom than RNA. RNA function: - CORRECT ANSWER Since DNA is the genetic blueprint of the cell, RNA is the messenger within the cell. It uses the bases in DNA to transfer to the ribosomes to make proteins. Transcription: - CORRECT ANSWER Cells copy the instructions in the DNA into RNA and send the messenger RNA to the ribosomes. Translation: - CORRECT ANSWER (Protein production) Proteins are made by the ribosomes from the information and send out to the entire cell. RNA is the messenger between DNA and protein production. (T or F) - CORRECT ANSWER True Indicate whether the following bases are found in DNA only, RNA only, or both DNA and RNA. A) Adenine B) Cytosine C) Guanine D) Thymine E) Uracil - CORRECT ANSWER A) both B) both C) both D) DNA E) RNA Prokaryotic cells: - CORRECT ANSWER Bacteria (both Eubacteria and Archaebacteria) have the most basic types of cells that can exist independently of each other. Organelles: cell wall, cytoplasm, organelles, nucleoid, plasmid, ribosomes, and flagella or pili. Cell wall (Prokaryotic): - CORRECT ANSWER An outside, rigid layer that separates the inside and outside of the cell and an inside plasma membrane that is semipermeable that allows certain substances inside and out of the cell. Cytoplasm (Prokaryotic): - CORRECT ANSWER An inner layer that is a rich protein fluid with gel-like consistency that houses organelles. Nucleoid (Prokaryotic): - CORRECT ANSWER The condensed DNA of the cell; contains genes and genetic blueprints needed for the formation of proteins that make up the machinery for the cell. Plasmid (Prokaryotic): - CORRECT ANSWER Small, circular portions of DNA that are not associated with the nucleoid. They contain a small number of genes compared to the DNA in the nucleoid. Chemically similar to DNA. Ribosomes (Prokaryotic): - CORRECT ANSWER Manufacture protein for the cell from the RNA messages. Small bodies that are free-floating in the cytoplasm. Flagella (Prokaryotic): - CORRECT ANSWER Long and whip-like used for the movement of the cell. Bacteria also have "pili" which are used for movement as well as the transfer of genetic information. Eukarya: - CORRECT ANSWER Eukarya contain eukaryotic cells which are more complex and much larger than prokaryotic cells. Plasma membrane (Eukaryotic): - CORRECT ANSWER Envelopes the cell and is semipermeable allowing certain substances in and out of the cell. The cytoplasm contains organelles and is gel-like. Ribosomes (Eukaryotic): - CORRECT ANSWER Function like ribosomes of prokaryotic cells, are used to make proteins based on RNA messages. Endoplasmic reticulum (ER) (Eukaryotic): - CORRECT ANSWER A tubular transport network within the cell, a stack of flattened membraneous sacs. It is responsible for moving proteins from one part of the cell to another and for moving proteins to the outside of the cell (secretion). Two types: smooth and rough. ***Rough ER: studded with ribosomes causing a rough appearance. ***Smooth ER: important for numerous metabolic processes. Golgi apparatus (Eukaryotic): - CORRECT ANSWER Involved in the packing and transport of proteins in the cell, including protein secretion. It refines proteins that have been manufactured by the ribosomes, it sorts the proteins and prepares them for transport to other parts of the cell or for secretion. Works hand in hand with the ER. Vesicles (Eukaryotic): - CORRECT ANSWER Small membrane-bound sacs within the cytoplasm. Used to transport proteins or other substances in or out of the cell. Three common types: vacuoles, lysosomes, and peroxisomes. ***Vacuoles: basic storage unit of the cell and can hold various compounds. ***Lysosomes: contain digestive enzymes that are capable of disposing of cellular debris and worn cell parts. ***Peroxisomes: rid the body of toxic components, such as hydrogen peroxide, major sites of oxygen use and energy production. (Liver contains many peroxisomes because of the toxic buildup). Mitochondria (Eukaryotic): - CORRECT ANSWER The powerhouse of the cell, site of where ATP is produced. Large kidney-bean shaped organelles surrounded by membranes. They also contain membranes inside which are a series of folds called "cristae" where enzymes are found. Enzymes on the cristae help convert sugar into ATP to power the cell. Microtubules (Eukaryotic): - CORRECT ANSWER Cellular tracks, that during mitosis, form the mitosis spindle. The spindle helps to segregate the chromosomes during cell division. ***Centrosomes: microtubules-organizing centers that help to form and organize the mitotic spindle during mitosis. Nucleus (Eukaryotic): - CORRECT ANSWER A large organelle in the center of the cell enclosed by a double membrane with pores in it. It is the control center of the cell because it contains the genetic information and directs all activities of the cell. Nucleolus (Eukaryotic): - CORRECT ANSWER A small body within the nucleus and functions to produce ribosomes that get moved to the cytoplasm. Chloroplasts (Plant cells): - CORRECT ANSWER Large organelles that contain chlorophyll, which allows the capture of sunlight to be used for production of glucose during photosynthesis. Chloroplasts are similar to mitochondria but pant cells need both chloroplasts and mitochondria to function. ***Have a solid cell wall to maintain structure. ***Have larger vacuoles to maintain cell pressure.
