Exam 3: Cell Division and Inheritance

In adult animals,cells move through the cell cycle with varying levels of speed.Cells that have differentiated and taken on specific roles may not divide whereas those that are exposed to harsh conditions,such as a low pH,may turnover regularly.On the other hand animals that are rapidly growing must generate cells rapidly.Which choice represents the correct pairing based on cell type and speed through the cell cycle?

During anaphase of mitosis

A major characteristic that distinguishes meiosis from mitosis is

For each spermatogonium which undergoes meiosis and spermatogenesis,__________ functional sperm are produced.

Occasionally,a cell will have more or less than the diploid number of chromosomes,called

A classic example of multiple allele inheritance is

In regard to blood type,what is the phenotype of an individual whose genotype is I^Ai?

When a cell synthesizes RNA from DNA that cell has undergone

An error known as __________,which may occur during meiosis,will result in gametes having a lesser or greater number of chromosomes than normal.

The process by which a copy of the DNA molecule is produced is referred to as

In DNA replication,because each new strand contains half of the original strand,this process is said to be:

During prophase of mitosis

Telophase begins when

A tool used by geneticists to help predict the results of crosses is the

A DNA nucleotide contains

During metaphase of mitosis

The purine bases of the nucleic acids are

The expected genotype ratio in the F2 generation of a monohybrid cross is

The two major kinds of molecules that direct the synthesis of proteins in eukaryotic cells are

The form of RNA that carries amino acids to ribosomes and helps position them for incorporation into a polypeptide is
