What must happen before meiosis can begin DNA doubles and produces sister chromatids?

Answer: Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied. Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy, and a paternal copy. … DNA replication occurs in the same fashion as it does during mitosis.

What must happen before meiosis can begin a DNA doubles and produces sister chromatids B the four Tetrads must be pulled apart C the cell membrane pinches together d four gametes must be produced?

Answer Expert Verified

Your answer is B, the chromosomes must replicate. Meiosis is a process which takes one diploid cell (46 chromosomes) and makes 4 haploid cells (23 chromosomes). In order to do this, the DNA must divide.

What must happen before meiosis can begin apex Brainly?

What must happen before a cell can begin mitosis quizlet?

What must happen before a cell can begin mitosis? The chromosomes must be duplicated, which occurs during interphase. … Telophase is the final phase of mitosis, when the chromosomes have arrived at the poles and the nuclear envelopes of the two new cells form.

What might happen before meiosis can begin?

Before entering meiosis I, a cell must first go through interphase. This is the same interphase that occurs before mitosis. The cell grows, copies its chromosomes and prepares for division during the G 1​start subscript, 1, end subscript​​ phase, S phase, and G 2​start subscript, 2, end subscript phase of interphase.

What is produced by meiosis apex answers?

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

What are the four stages of mitosis?

These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
