• A unit of cell division

• A type of carbohydrate

Explain the role of alleles in gene expression.

• They are types of chromosomes

• They code for proteins

• They are different versions of the same gene

• They regulate cell division

Define a chromosome.

• A cell organelle

• Structures made of protein and DNA

• A type of gene

• A form of energy storage

Why are chromosomes essential during cell division?

What is meiosis, and where does it occur?

• Cell division in body cells

• Cell division in reproductive cells, ovaries, and testes

• DNA replication process

• Formation of somatic cells

Describe the process of DNA replication in meiosis.

• Chromosomes line up in the middle

• Formation of daughter cells

• Splitting of DNA strands and matching with complementary bases

• Production of energy

What happens during crossing over in meiosis?

• Chromosomes switch genetic information

• Formation of gametes

• DNA replication

• Mutations in DNA

What is the purpose of independent assortment in meiosis?

• Creates genetic diversity

• Controls cell growth

What is the outcome of meiosis, and what are the resulting cells called?

• Two identical cells, called gametes

• Four daughter cells, called gametes

• Four daughter cells, each with one set of chromosomes, called gametes
