Question

What changes can be observed in cell cycle when a cell has produced a defective copy of Chromosomes during S-phase?​

Answer 1

Answer:

Diploid

Explanation:

S or synthesis phase is the period during which DNA synthesis or replication takes place. During this time the amount of DNA doubles. If the initial amount of DNA is denoted as 2C then it increases to 4C.

Although, there will be no increment in chromosome number: for e.g. if a cell has the 2n number of chromosomes at G

, even after S phase the number of chromosomes remains the same, i.e., 2n. before the cell enters into the S-phase, it has the DNA in the form of chromatin not chromosome. Chromosomes are formed when the DNA is replicated during the S - phase.
