What is the main purpose of the sequences of nitrogen bases?
A
gives DNA the shape needed for translation
B
prevents mutations when coding for amino acids
C
forming the hydrogen bonds between the bases
D
carries instructions for the traits of an orgainsm
Explanation: 

Detailed explanation-1: -The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA.

Detailed explanation-2: -A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. These bases are crucially important because the sequencing of them in DNA and RNA is the way information is stored.

Detailed explanation-3: -What is the Main Purpose of the Sequences of Nitrogenous Bases in DNA? The nitrogenous bases are like the foundation of DNA and RNA which is collectively known as Nucleic acids. The main purpose of sequences of nitrogenous bases in DNA is to store the genetic information of the organisms in them.

Detailed explanation-4: -The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.

Detailed explanation-5: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
