The four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).
These bases form specific pairs (A with T, and G with C).
<h3>What is DNA nucleotides?</h3>
Nucleotides can be defined as those organic substances consisting of a nucleoside and a phosphate.
They serve as monomeric units of the nucleic acid polymers –
- Deoxyribonucleic acid
- Ribonucleic acid,
So therefore, the four types of nitrogen bases of dna nucleotides are:
- Adenine (A)
- Cytosine (C)
- Ganine (G)
- Thymine (T).

Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
I think the correct answer from the choices listed above is the second option. Lysosomes can be compared to the recycling and garbage centers of a city. This can be justified since they <span>digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.</span>
