3.3.1 Protein Synthesis

Which process produces copies of DNA? (DNA → DNA)

Replication

Which process produces RNA? (DNA → RNA)

Transcription

Which process produces proteins? (RNA → Protein)

Translation

What is the role of p53 during DNA replication? Read carefully to find the differences between the option choices.

p53 is a cell cycle inhibitory protein that pauses progression of the cell cycle to correct DNA mutations.

What are the differences between DNA and RNA? Read carefully to find the differences between the option choices.

DNA = double-stranded, built of deoxyribose sugar, contains nitrogen base thymine. RNA = single-stranded, built of ribose sugar, contains nitrogen base uracil.

What are the two steps of protein synthesis in chronological sequence?

Transcription → Translation
