Question

human somatic cells have 46 chromosomes. how many chromosomes will be present in a human somatic cell after interphase? how many chromatids after interphase?

Explanation:

Step1: Understand interphase process

During interphase, DNA replication occurs. But the number of chromosomes remains the same before cell - division starts. A human somatic cell starts with 46 chromosomes and still has 46 chromosomes after interphase.

Step2: Determine chromatid number

After DNA replication in interphase, each chromosome consists of two sister chromatids. Since there are 46 chromosomes, the number of chromatids is 46×2 = 92.

Answer:

Number of chromosomes after interphase: 46
Number of chromatids after interphase: 92
