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).

<h2>a combining form with the meanings “living substance,” “tissue,” “substance of a cell,” used in the formation of compound words: endoplasm; neoplasm; cytoplasm</h2>
Answer:
The correct answer is B. A gamete carries one allele for a gene.
Explanation:
Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to the Law of segregation given by Gregor Mendel-
During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.
Thus, option B) is the right answer.
