If an organism's diploid number is 12, its haploid number is:

• 12

• 6

• 24

• 3

Gametes are produced by the process of:

• mitosis

• meiosis

• crossing-over

• replication

What does a tetrad consist of?

• a homologous pair of chromosomes, each made of two chromatids

• the four copies of a chromosome that are normally present in cells

• two sister chromatids that have each been replicated during interphase

• a parental chromosome that was replicated to form a pair, then replicated again

Chromosomes form tetrads during what phase of meiosis?

• metaphase I of meiosis

• interphase

• anaphase II of meiosis

• prophase I of meiosis

Unlike mitosis, meiosis results in the formation of:

• diploid cells

• haploid cells

• 2N daughter cells

• body cells

What is formed at the end of meiosis?

• two genetically identical cells

• four genetically different cells

• four genetically identical cells

• two genetically different cells

What stores information in a cell?

• proteins

• carbohydrates

• lipids

• DNA

Which of the following is a nucleotide of DNA?

• adenine + phosphate group + thymine

• cytosine + phosphate group + guanine

• deoxyribose + phosphate group + polymerase

• deoxyribose + phosphate group + cytosine

Because of base pairing in DNA, the percentage of:

• adenine is equal to the percentage of guanine

• thymine is equal to the percentage of adenine

• adenine is much greater than the percentage of thymine

• cytosine is much greater than the percentage of guanine
