Unit 4 DNA & Mitosis Review

Front

What is a Chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information. Humans have 23 pairs of chromosomes.

Front

What happens during Telophase?

Back

During Telophase, a nuclear membrane forms around each group of chromosomes, marking the end of mitosis.

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell grows and copies its DNA in preparation for mitosis.

Front

What occurs during Interphase?

Back

During Interphase, the DNA is duplicated, and the cell prepares for division.

Front

Why is DNA important?

Back

DNA serves as the blueprint for traits of all living things, determining characteristics and functions.

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is Cytokinesis?

Back

Cytokinesis is the final step of cell division where the cytoplasm divides, resulting in two separate cells.

Front

What are Alleles?

Back

Alleles are different forms of a gene that determine specific traits, such as eye color.

Front

What is a Phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries genetic information in living organisms.
