Exam 4: Genes and Cellular Function

A karyotype shows the chromosomes sorted and isolated from a cell in .

A cell finishing mitosis has DNA molecules, while a cell finishing DNA replication has DNA molecules.

The gene coding for a polypeptide made of 51 amino acids would have a minimum number of

Germ cells have unpaired chromosomes and are thus called cells.

All of the body's nonreproductive cells, called , usually have and are thus called cells.

After mitosis each chromosome consists of two parallel filaments called sister chromatids.

This figure shows the DNA structure.What does "C" represent?

Mitosis is responsible for embryonic development and tissue growth.

DNA replication is called semiconservative because

The human genome consists of

Eye color is caused by genes at multiple loci.This phenomenon is called

After translation, a protein may undergo structural changes called modifications.

Many genes occur in alternative forms called alleles.

DNA is a polymer of , which consist of a sugar, a phosphate group, and a .

G1, S, and G2 phases of the cell cycle are collectively called

is the DNA base sequence complementary to the strand TGCCAT.

Transcription occurs in the , but most translation occurs in the .

Which of the following omits some stage(s) of the cell cycle?

The enzyme RNA polymerase participates in translation.

are turned on or off by regulatory proteins in accordance with changing needs for the they encode.
