(Unit SB3 - Heredity Concept Question)

The diagram below represents DNA replication in which a mutation has occurred at Point X. During the cell cycle, this mutation at Point X can result in the production of a mutated protein in which cell?

• The parent cell only

• one somatic cell only

• one somatic cell and one parent cell

• both somatic cells and the parent cell.

In order to ensure an exact copy of DNA is passed on, replication must occur before

• electron transfer

• mitosis

• protein synthesis

• glycolysis

NGSS.HS-LS1-4

Which best describes the process that occurs when nuclear DNA codes for a protein in the cytoplasm?

• One strand of the DNA remporarily leasved the nucleus to be translated by a ribosome in the cytoplasm.

• mRNA is transcribed from DNA and leaves the nucleus to be translated by tRNA in the cytoplasm.

• A ribosome makes an RNA copy of DNA in the nucleus, then returns to the cytoplasm for protein synthesis.

• The tRNA copies the DNA in the nucleus, then transports the information to the ribosomes in cytoplasm for protein synthesis.
