Answer: Posterior HoxA and HoxD genes play important roles in patterning along the proximodistal axis of the forelimb (10–13). They also are required for activating and maintaining Shh expression in the developing forelimb (6, 7). mark brainliest
Explanation:
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.
Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
