|
|
A long sequence of nucleotides in a specific order codes for a genetic trait.

Explanation:
Detailed explanation-1: -Genetic Code: The sequence of nucleotides, coded in triplets (codons) along the mRNA, that determines the sequence of amino acids in protein synthesis. A gene’s DNA sequence can be used to predict the mRNA sequence, and the genetic code can in turn be used to predict the amino acid sequence.
Detailed explanation-2: -The part of the nucleotide that stores genetic information is A. nitrogen base. There are five main bases namely adenine, guanine, cytosine, thymine, and uracil. The sequence of these bases in DNA or RNA determines the genetic information contained in the molecule.
