Ans.
The Sanger sequencing or chain-termination method for sequencing involves use of ddNTPs (dideoxyribonucleotide triphosphates) to identify the sequence of nucleotides in a DNA segment. The ddNTPs are nucleotide derivatives that lack both the 2'- and 3'-hydroxyl group, hence called dideoxyribonucleotides. When a ddNTP is added to a growing chain of DNA, absence of 3'-hydroxyl group leads to termination of growing chain as this ddNTP cannot make phosphodiester bond with a NTP and DNA sequence can be identified.
Thus, the correct answer is option C).

Answer:
This question is incomplete
Explanation:
However, mRNA can be built from a DNA sequence; i.e a DNA strand is used as a template for the production of an mRNA sequence. This process occurs during transcription. While the four nitrogenous bases in a DNA molecule are adenine, thymine, guanine and cytosine, in RNA the thymine is absent and replaced with uracil. While producing the mRNA strand, Uracil will be complementary to adenine, adenine will be complementary to thymine, guanine will be complementary to cytosine and cytosine will be complementary to guanine. This can be seen in the illustration below:
DNA sequence: T--G--G--C--A--G--C--T--A--C--C--G
mRNA sequence: A--C--C--G--U--C--G--A--U--G--G--C
Thus, while building a mRNA nucleotide sequence, the procedure above can be followed
The answer is C because all of the spheres of the earth exchange energy and mass.
