Question

The codon chart shown here uses the three base sequence found on the mrna molecule after the information is copied from dna during transcription. imagine that a protein is being assembled at the ribosome. what is the amino acid sequence for the codons guu aaa? responses a valine - lysinevaline - lysine b leucine - lysineleucine - lysine c valine - argininevaline - arginine d leucine - arginine

A) Valine - Lysine
B) Leucine - Lysine
C) Valine - Arginine
D) Leucine - Arginine

Answer 1

The mRNA codons 'GUU' and 'AAA' translate to the amino acids Valine and Lysine, respectively, during protein synthesis.

Step-by-step explanation:

The question concerns the translation of an mRNA sequence into an amino acid sequence during protein synthesis. The mRNA codons 'GUU' and 'AAA' translate to amino acids. According to the codon chart, 'GUU' corresponds to Valine and 'AAA' corresponds to Lysine. Therefore, the correct amino acid sequence for the codons 'GUU AAA' would be Valine followed by Lysine. This adheres to the genetic code which is a set of rules used by living cells to translate the information encoded within genetic material (RNA sequences) into proteins.
