A somatic cell that has just completed the S phase of its cell cycle, as compared to gamete of the same species, has : [2015 RS]
- a)twice the number of chromosomes and four times the amount of DNA
- b)same number of chromosomes but twice the amount of DNA
- c)four times the number of chromosomes and twice the amount of DNA
- d)twice the number of chromosomes and twice the amount of DNA
Correct answer is option 'B'. Can you explain this answer?

A somatic cell that has just completed the S phase of its cell cycle, ...
The correct option is Option B.
A somatic cell that has just completed the S phase of its cell cycle has replicated its DNA but has not yet undergone cell division (mitosis). Therefore, it has the same number of chromosomes as before S phase but twice the amount of DNA, because each chromosome has been replicated into two sister chromatids.

A somatic cell that has just completed the S phase of its cell cycle, ...
When a somatic cell undergoes in s phase then it's DNA content gets double as there is replication of DNA occur in S phase but no. of chromosome remains same it is becz there is no seperation of centromere, all these are comprision to normal somatic cell. BUT in the ques. It is compared to gamet so, no of chromosome would be doubled and amount of DNA would be 4times.

A somatic cell that has just completed the S phase of its cell cycle, ...
**Explanation:**
During the S phase of the cell cycle, DNA replication occurs. This results in the synthesis of an identical copy of each chromosome.
**Somatic cell after S phase:**
A somatic cell is a non-reproductive cell that makes up the majority of the body's cells. After the S phase, a somatic cell will have twice the amount of DNA, as each chromosome is duplicated. However, the number of chromosomes remains the same, as the duplicated chromosomes are still considered as a single chromosome.
**Gamete:**
Gametes are reproductive cells (sperm and eggs) that are involved in sexual reproduction. Gametes are produced by a process called meiosis, which involves two rounds of cell division. During meiosis, the number of chromosomes is halved to produce haploid cells (cells with half the number of chromosomes). Therefore, gametes will have half the number of chromosomes compared to somatic cells.
**Comparison:**
- Somatic cell after S phase:
- Number of chromosomes: Remains the same
- Amount of DNA: Twice the amount
- Gamete:
- Number of chromosomes: Half the number
- Amount of DNA: Varies depending on the species, but it is typically the same as the amount of DNA in somatic cells after the S phase.
Therefore, the correct answer is option **B) twice the number of chromosomes and four times the amount of DNA**.
