Question
Biology Question on the molecular basis of inheritance
In split genes, the coding sequences are called
A
exons
B
cistrons
C
introns
D
operons.
Answer
exons
Explanation
Solution
Split gene are those genes that consist of continuous sequence of nucleotide (coding sequence) interrupted by intervening sequences. Most eukaryotic genes are split as are genes of some animal viruses. The continous coding sequences are called exons and the intervening non-coding sequence are called introns. These introns are not represented in wRNA transcribed from the gene and are not utilized for the synthesis of proteins.
