Does meiosis have an interphase where chromosomes are replicated?
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.
What happens before meiosis begin?
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
Which period are chromosomes duplicated in?
During the cell cycle, chromosomes are duplicated during the interphase.
Why do the chromosomes become easier to see under the microscope just before mitosis?
during mitosis and meiosis because the condensed chromosomes are thicker and therefore more prominent.
What stage are Chromosomes duplicated?
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
When do chromosomes replicate during meiosis?
Chromosomes replicate in the Interphase part of Meiosis and throughout the whole process of Meiosis they only replicate once.
Before mitosis or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.

What must happen before meiosis or mitosis can take place?
Before Meiosis 2, the cell must first go through Meiosis 1. This is when the cell splits into two cells, each with two chromosomes.
Which period are chromosomes duplicated in?
During the cell cycle, chromosomes are duplicated during the interphase.
Why do the chromosomes become easier to see under the microscope just before mitosis?
during mitosis and meiosis because the condensed chromosomes are thicker and therefore more prominent.
In what stages of the reproductive process does meiosis occur?
in the production of eggs and of sperm the mitosis stage before the chromosomes are copied
How many chromosomes will the resulting cells have in mitosis?
This depends both on the cell undergoing mitosis and the stage in mitosis which is currently underway. Humans have 46 chromosomes per cell, but in some stages of mitosis have 92. Dogs have 78 chromosomes, but at some stages of mitosis have 156.
Why must S phase come before mitosis?
Two sets of chromosomes must be available before mitosis so that each of the two daughter cells will have an entire set of chromosomes
What stage are Chromosomes duplicated?
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
Which phase occurs before mitosis or meiosis?
Inter-phase occurs before mitosis or meiosis.
