Inheritance Review

Which of these options define Gene Expression?

• A nucleotide polymer that uses deoxyribose in its sugar phosphate backbone and forms the hereditary material of all life on earth

• A single linear or circular piece of DNA that contains some or all of an organisms gene.

• The process by which genetic information generates a specific protein or trait.

• A segment of DNA that encodes a protein or functional RNA

Which of the following best explains why red blood cells and skin cells have different structures and functions, despite containing the same DNA?

• Different cells contain different numbers of genes

• Different cells replicate their DNA differently.

• Different cells express different combinations of genes

• Different cells can modify the types of genes on the DNA.
