Guida verificata passo dopo passo1
Understand that a chromatid is one half of a duplicated chromosome. After DNA replication, each chromosome consists of two sister chromatids.
Identify the number of chromosomes in the original cell, which is given as 46 chromosomes.
During DNA replication, each chromosome is duplicated, resulting in two sister chromatids per chromosome.
Calculate the total number of chromatids by multiplying the number of original chromosomes by 2, since each chromosome forms two chromatids after replication.
Express the calculation using MathML: to find the total number of chromatids after replication.
