Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
DNA sequencing is a technique used to
A
Identify the bases if tRNA
B
Identify the bases of the mRNA
C
Identify the bases of RNA
D
Identify the order of DNA bases
Explanation: 

Detailed explanation-1: -DNA sequencing refers to the general laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule. The sequence of the bases (often referred to by the first letters of their chemical names: A, T, C, and G) encodes the biological information that cells use to develop and operate.

Detailed explanation-2: -Regions of DNA up to about 900 base pairs in length are routinely sequenced using a method called Sanger sequencing or the chain termination method. Sanger sequencing was developed by the British biochemist Fred Sanger and his colleagues in 1977.

Detailed explanation-3: -The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C). Base pair may also refer to the actual number of base pairs, such as 8 base pairs, in a sequence of nucleotides.
