Naked DNA is called chromatin.

The genetic code is the link between the __________ and the __________ that they represent.

A cell starting prophase has 92 molecules of DNA in its nucleus.

DNA is composed of double-ring nitrogenous bases,whereas RNA is composed of single-ring nitrogenous bases.

The human genome consists of approximately __________ pairs of nucleotides.

Sister chromatids are pulled to opposite poles of a cell during __________ of the cell cycle.

Germ cells have __________ unpaired chromosomes and are thus called __________ cells.

Cytokinesis overlaps with which phase of mitosis?

A __________ contains the necessary information for the production of a molecule of RNA.

In familial hypercholesterolemia,individuals with two abnormal alleles die of heart attacks in childhood,those with only one abnormal allele typically die as young adults,and those with two normal alleles have normal life expectancies.This exemplifies __________.

If one allele is not phenotypically expressed in the presence of another,we say that it is a(an)__________ allele.
