True
B
False
Verified step by step guidance1
Understand the structure of chromosomes during the cell cycle. Chromosomes undergo various structural changes as a cell progresses through the cell cycle stages: interphase and mitosis.
Recognize that interphase is the phase where the cell spends most of its life. It includes the G1, S, and G2 phases, during which the cell grows, duplicates its DNA, and prepares for mitosis.
During interphase, chromosomes are in a less condensed form known as chromatin. This allows for the necessary processes of transcription and DNA replication to occur efficiently.
In contrast, during mitosis, chromosomes become highly condensed to facilitate their segregation into daughter cells. This is when they are most visible under a microscope.
Conclude that interphase chromosomes are less condensed compared to their state during mitosis, making the statement 'Interphase chromosomes are more condensed than other forms of chromosomes' false.
