During which phase does the DNA make a copy of itself?
|
interphase
|
|
prophase
|
|
metaphase
|
|
anaphase
|
Explanation:
Detailed explanation-1: -S phase is the period during which DNA replication occurs.
Detailed explanation-2: -Because of this, DNA makes a copy of itself in a process known as replication during interphase, a stage that occurs before cells divide.
Detailed explanation-3: -Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.
Detailed explanation-4: -The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase. During the S phase, DNA is duplicated into two sister chromatids, and centrosomes, which give rise to the mitotic spindle, are also replicated.
