Question

question 1
during g1 phase,
chromosomes consist of one long dna molecule and associated proteins
chromosomes consist single stranded dna
chromosomes are in the process of being replicated
chromosomes consist of two identical dna molecules

Explanation:

During the G1 phase of the cell cycle, chromosomes are in their unreplicated state. They consist of one long DNA molecule (along with associated proteins). DNA replication occurs in the S - phase. Single - stranded DNA is not the normal state of chromosomal DNA (chromosomal DNA is double - stranded). Chromosomes are replicated in the S - phase, not in G1. And chromosomes consisting of two identical DNA molecules (sister chromatids) occur after S - phase (in G2 and M - phases).

Answer:

chromosomes consist of one long DNA molecule and associated proteins
