Mitosis vs Meiosis

Front

Why is it important for a cell to replicate DNA before it divides in mitosis or meiosis?

Back

It allows the genetic information to be transferred into the daughter cells.

Answer explanation

Replicating DNA before cell division is important to transfer genetic information into daughter cells.

Front

The end of mitosis results in ____ to each other.

Back

2 cells that are identical

Answer explanation

The end of mitosis results in the formation of 2 cells that are identical to each other.

Front

What phase is shown here?

Back

Metaphase I

Answer explanation

Metaphase I is the correct phase shown here. During Metaphase I, homologous chromosomes align at the metaphase plate.

Front

What phase is shown here? Options: Anaphase I, Prophase I, Metaphase II, Metaphase I

Back

Metaphase II

Answer explanation

The phase shown here is Metaphase II. In this phase, the chromosomes align at the equator of the cell.

Front

What phase is this? Options: Interphase II, Prophase I, Metaphase I, Anaphase II

Back

Prophase I

Answer explanation

This phase is Prophase I. It is the first phase of meiosis and involves the condensation of chromosomes and the pairing of homologous chromosomes.

Back

Metaphase II

Answer explanation

The phase shown here is Metaphase II. In this phase, the chromosomes align at the equator of the cell.

Front

What are chromosomes?

Back

condensed DNA

Answer explanation

Chromosomes are condensed DNA, which carry genes and genetic information.

Front

The process of crossing over occurs in what phase of meiosis?

Back

prophase 1

Answer explanation

Crossing over occurs during prophase 1 of meiosis, where genetic material is exchanged between homologous chromosomes.

Front

What phase is this? Options: Interphase II, Prophase I, Metaphase I, Anaphase II

Back

Prophase I

Answer explanation

This phase is Prophase I. It is the first phase of meiosis and involves the condensation of chromosomes and the pairing of homologous chromosomes.

Front

During meiosis, if an organism has 10 chromosomes, how many will the new daughter cells have?

Back

5

Answer explanation

During meiosis, the new daughter cells will have 5 chromosomes, as each daughter cell receives half of the original number of chromosomes.
