Genetics and Cell Division Quiz

What is a gene?

• A specific sequence of DNA that codes for a protein

• A structure that organizes chromosomes in the nucleus

• A segment of RNA that carries instructions for traits

• A molecule responsible for energy production

What is an allele?

• A version of a gene

• A type of protein

• A specific chromosome

• A structure in the nucleus

What is the purpose of mitosis?

• To produce gametes

• To repair damaged cells

• To reduce chromosome number by half

• To create identical daughter cells

During which phase of mitosis do chromosomes line up at the center of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

What happens during anaphase of mitosis?

• Chromosomes condense

• Chromosomes are copied

• Sister chromatids are pulled apart

• The nuclear membrane forms

How many daughter cells are produced by mitosis?

• 1

• 2

• 4

• 8

What is the key difference between mitosis and meiosis?

• Mitosis results in two identical cells, meiosis results in four unique cells

• Mitosis occurs only in gametes, meiosis occurs in somatic cells

• Mitosis reduces chromosome number, meiosis does not

• Mitosis involves the division of the nucleus, meiosis does not

During which stage of meiosis do homologous chromosomes separate?

• Prophase I

• Anaphase I

• Anaphase II

• Telophase II

What is the result of meiosis in terms of chromosome number?

• The chromosome number is halved

• The chromosome number doubles

• The chromosome number stays the same

• The chromosome number is tripled

Which of the following occurs during prophase I of meiosis?

• Chromosomes condense and homologous chromosomes pair up

• Sister chromatids separate

• Spindle fibers disappear

• The nuclear membrane forms
