Respuesta :
If the cell has 6 unreplicated chromosomes in G1, there’ll be 12 double helices after replication since there will be twice as many as unreplicated chromosomes.
What about unreplicated chromosomes?
- One double stranded DNA molecule is often found on an unreplicated chromosome.
- The chromatids, which are two identical double stranded DNA molecules connected at their centromere, make up a replicated chromosome.
- Each homologous pair of chromosomes—one paternal and one maternal chromosome of the same type—is unreplicated before the S phase.
- The unreplicated chromosomes replicate within the S phase.
- After meiosis I, all chromosomes are replicated.
- In actuality, chromosomal replication occurs prior to meiosis.
- During the S phase, DNA replication takes place.
- There are two haploid cells at the end of meiosis I, each having one replicated copy of each chromosome (1n).
- Bivalents are not created since each homolog is only found in one copy.
