Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which are the 4 DNA bases?
A
RNA, adenine, thymine, guanine
B
uracil, adenine, guanine, thymine,
C
adenine, thymine, cytosine guanine
D
RNA, DNA, ribosome, protein
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -These chemical bonds act like rungs in a ladder and help hold the two strands of DNA together. There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).

Detailed explanation-3: -Base Pair Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) [GWA-NeeN] or thymine (T).

Detailed explanation-4: -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-5: -nitrogenous bases-there are four of these: adenine (A), thymine (T), cytosine (C), guanine (G)
