Exam 4: Genes and Cellular Function

Although all cells synthesize phospholipids, there are no genes for phospholipids.

Anticodons, codons, and base triplets correspond to , respectively.

Copying genetic information from DNA into RNA is called , whereas using the information contained in mRNA to make a polypeptide is called )

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

All the DNA in one 23-chromosome set is called

If a DNA molecule was known to be 22% thymine (T), what would be the percentage of guanine (G)?

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

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

All these can cause a mutation except

Sister chromatids migrate to opposite poles of a cell during

A gene can be defined as an information-containing segment of RNA that codes for the production of a polypeptide.

The allele for cleft chin (C) is dominant to the allele for uncleft chin (c).A male and female who are both heterozygous for cleft chin have a child.What is the chance that this child will have an uncleft chin?

All of the following are directly involved in translation except

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

There are three codons that do not code for any amino acid.

Oncogenes and tumor-suppressor genes have similar effects on cell division.

DNA never migrates from the nucleus to the cytoplasm to participate directly in protein synthesis.

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

Phenotype is the result of genetic influences only.

All proteins made by the ribosomes are exported from a cell for use elsewhere in the body.
