Question

You have the DNA base sequence of a particular gene from sweet pea and from species X and Y. A computer analysis reveals that species X has a 95% DNA sequence homology to the pea gene (5% of the bases in the species X gene sequence are different), while species Y has a 90% DNA sequence homology (10% of the bases in species Y gene sequence are different). Can you conclude that the protein in sweet pea is more similar in structure and function to that in species X than in species Y? Please explain the steps you take to solve and explain why

Answer 1

We can conclude that the protein in sweet pea is more similar in structure and function to that in species X than in species Y. It could be proved further with the computer modeling of protein on account of aminoacid sequence.
