What is the complementary sequence to 3’ ATG CGA ATA 5’?
(0/1 Points)
3’ TAT TCG CAT 5’
3’ TAC GCT TAT 5’
The correct answer is 3' TAT TCG
... [Show More] CAT 5'. Remember complementary means “Matching
or Pairing” You have to remember to pay attention to your numbers as well as your
letters (A-T, G-C, 5'-3'). The correct answer is 3’ ATG CGA ATA 5’ (original sequence) 5’
TAC GCT TAT 3’ (complementary sequence) But we asked for it in the 3’ direction, so
mirror answer to give correct answer: 3’ TAT TCG CAT 5’ If you chose 3' TAC GCT TAT 5',
this is incorrect. Although the nucleotides are in the correct order, the 5' and 3' are in
the wrong place. DNA strands that are complementary run in opposite directions. This
means that if one strand starts with a 3', the the complementary strand must start with
a 5'. If none of the answer choices give the correct answer in 5' ---> 3', then you need to
write its mirror, which will run from 3' ---> 5'.
3’ GAT AGC ATA 5’
5’ ATA AGC GTA 3’
Which amino acid sequence would result from this Coding DNA strand?
3’ ATG CAG ATA 5’?
(1/1 Points)
Tyr Val Tyr
Ile Gln Ile
Ile Asp Val
The correct answer is Ile Asp Val. We are starting at the coding strand, and have to
remember the relationship between coding DNA and mRNA. These two strands are noncomplementary and parallel. So we copy the coding strand , change T ---> U, and then
write the mRNA sequence: 3’ ATG CAG ATA 5’ coding 3’ AUG CAG AUA 5’ mRNAMirror by
changing orientation: 5’ AUA GAC GUA 3’ Read chart Ile Asp Val (chart is in direction of
5' ---> 3')
Leu His Lys
Which amino acid sequence would be made from this template DNA
strand? 5’ TAT TAC CGA 3’?
(1/1 Points)
Tyr Tyr Arg
Ile Met Ala
Ser Val Ile
The correct answer is Ser Val Ile because 5’ TAT TAC CGA 3’ template is complementary
and antiparallel so 3’ AUA AUG GCU 5’ but it is in the wrong orientation, so mirror 5’
UCG GUA AUA 3’ and read the chart Ser Val Ile
Ser His Gln
