Biology DNA and RNA test

Question 1

Name the 2 types of cell division and state the differences.

Answer 1

Mitosis – creates 2 identical cells to the parent. Produces body cells
Meiosis – creates 4 genetically different cells. Produces sex cells (sperm & egg)

Question 2

What is the difference between the cell cycle and cell division?

Answer 2

The cell cycle is a series of events that a cell goes through in order to divide. It includes interphase, mitosis and cytokinesis.
Cell division includes mitosis (PMAT) and cytokinesis. It is the steps a cell goes through while dividing

Question 3

Describe the purpose of mitosis and list the 2 reasons for mitosis?

Answer 3

Mitosis purpose is to create body cells that are identical to the parent cell. It takes place in order to replace damaged and worn out cells.

Question 4

What are the 4 main parts of the cell that are involved in mitosis?

Answer 4

Centrioles, Spindle fibers, Nucleus/nuclear membrane, and DNA

Question 5

Explain the difference between a chromatid, sister chromatids, chromosomes, duplicated chromosomes and chromatin?

Answer 5

Chromatin, A ball of tightly coiled DNA found inside the nucleus. Interphase.

Question 6

Explain the difference between a chromatid, sister chromatids, chromosomes, duplicated chromosomes and chromatin?

Answer 6

Sister Chromatids, Also known as duplicated chromosomes. Visible in the form of an X. Prophase, metaphase.

Question 7

Explain the difference between a chromatid, sister chromatids, chromosomes, duplicated chromosomes and chromatin?

Answer 7

Duplicated Chromosome, Also known as sister chromatids. Visible in the form of an X. prophase, metaphase
