Transcription

What does the DNA inherited by an organism dictate?

• The synthesis of carbohydrates

• The synthesis of proteins

• The synthesis of lipids

• The synthesis of vitamins

What is gene expression?

• The process by which DNA directs protein synthesis

• The process by which RNA is replicated

• The process by which cells divide

• The process by which genes mutate

What is the role of proteins in genetic information?

• They are the links between genotype and phenotype

• They store genetic information

• They replicate DNA

• They mutate genes

In which type of cell does the nuclear envelope play a role in separating transcription and translation?
