Answer:
For the DNA sequence TGG-AAC-CAA, which is transcribed in the mRNA as ACC-UUG-GUU, the coding amino acid sequence is Thr-Leu-Val
Explanation:
The DNA molecule contains a specific sequence of bases, which is transcribed into a messenger RNA (mRNA) molecule, a process that occurs according to the complementarity of nitrogenous bases.
The sequence of mRNA bases is organized into codons —formed by the binding of a triplet of bases— each of which encodes an amino acid that will be incorporated into the protein molecule.
For a DNA sequence TGG-AAC-CAA, the resulting mRNA is ACC-UUG-GUU, which occurs by the complementarity of nitrogen bases. Of the three codons obtained:
- ACC encodes the amino acid Thr or Tyrosine
- UUG encodes the amino acid Leu or Leucine
- GUU encodes the amino acid Val or Valine
So the DNA fragment TGG-AAC-CAA is obtained the amino acid sequence Thr-Leu-Val.
