Vedclass · Answer

(A) In a diploid somatic cell during the $G_1$ phase,the $DNA$ content is $2C$ and the chromosome number is $2n$. In a haploid gamete,the $DNA$ content is $1C$ and the chromosome number is $n$. The $S$ phase is characterized by the replication of $DNA$,which doubles the amount of $DNA$ per cell. Therefore,in a somatic cell after the $S$ phase,the $DNA$ content becomes $4C$,while the chromosome number remains $2n$. Comparing this to a gamete ($1C$ $DNA$ and $n$ chromosomes),the somatic cell has $4$ times the $DNA$ ($4C$ vs $1C$) and $2$ times the number of chromosomes ($2n$ vs $n$).

$A$ somatic cell that has just completed the $S$ phase of its cell cycle,as compared to a gamete of the same species,has:
