Question 2
3.2 / 3.2 pts
Which of the following sequences best represents the overall flow of
information in a cell?
replication, division, protein processing, protein import
transcription, pre-mRNA processing, translation, protein processing, export

Question 3
3.2 / 3.2 pts
Animal development and automobile development differ in that
the initial components are simpler than the final product.
automobile development requires introduction of material from the outside.
animal development requires the input of energy.
information for developing an animal comes from within the animal.
automobile development can suffer from informational errors.

sequence in RNA (mRNA).
converting the information in amino acids back into DNA.
copying the information in ADP into ATP.
converting the amino acids in RNA into amino acids in proteins.
Question 5

one end and an amino acid attachment site at the other end:
an rRNA
RNA polymerase
a tRNA
an mRNA poly-A tail
a small ribosomal subunit
Question 9
3.2 / 3.2 pts
Which of the following is not a role of the ribosome or its subunits?
creating a channel for mRNA to enter and exit
helping tRNA anti-codons to bind to mRNA codons
comparing tRNA anti-codons against corresponding mRNA codons
binding amino acids together to form a polypeptide chain
generating ATP energy to be used by the cell in biosynthesis
Question 10
3.2 / 3.2 pts
There are more than four kinds of amino acids in proteins. Each kind of
amino acid must be coded for in mRNA. Thus, a short sequence of mRNA
bases called a(n) _________ is used to code for each amino acid in the
translation process.
