How many chromosomes would a cell have during metaphase 1 of meiosis if it has 12 chromosomes during interphase?
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
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 k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
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.
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
How chromosomes look before meiosis?
Threadlike
How many chromosomes does an egg of a human female have before meiosis?
23 chromosomes

What two things must happen to the sperm before it can fertilize an egg?
Well first the sperm has to be made by meiosis. Then it has to get to the egg and enter it [If you catch my drift.] Then after that the nucleus of both the sperm and the egg disappear and the chromosomes of both join together and a new nucleus forms. This creates a new dipliod cell, or a new organism in other words.
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
What phase of meiosis is when the chromosomes copied?
Interphase before Prophase I.

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).
