Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the 4 nitrogen bases?
A
adenine, thymine, cytoplasm, and guanine
B
adenine, thymine cytosine, and guanine
C
adenine, thymine, cytosine, and gylcerol
D
adenine, thymine, cytosine, and glucose
Explanation: 

Detailed explanation-1: -Two nitrogen-containing bases (or nucleotides) that pair together to form the structure of DNA. 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).

Detailed explanation-2: -There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).

Detailed explanation-3: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers made up of long chains of nucleotides.

Detailed explanation-4: -There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). A DNA molecule is composed of two strands. Each strand is composed of nucleotides bonded together covalently between the phosphate group of one and the deoxyribose sugar of the next.

Detailed explanation-5: -An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G).
