Question

Using the genetic code provided below, if a DNA template strand has the following sequence of triplets, T C A G C C T A A, the amino acids that will be strung together to form a protein will look like this:

a. serine arginine isoleucine
b. serine alanine stop
c. serine arginine stop
d. isoleucine arginine serine
e. serine stop isoleucine

Answer 1

Answer: option B

Step-by-step explanation:

Using the genetic code can help determine the amino acid sequence formed. On the genetic code, the 64 codons codes for 20 amino acids thus more that one codon can code for an amino acids. The codons are made up of a triplet of bases eg GCC. Thus starting with the first three, we have

TCA which encodes the amino acid serine

GCC which encodes the amino acid alanine

TAA - which is one of the three STOP condoms and do not encode for an amino acid.

Ser-Ala-stop
