Review 6: RNA & Gene Expression

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction.

Front

What is a mutation in DNA?

Back

A mutation is a permanent change in the sequence of nucleotides in DNA.

Front

Why is gene expression important in cells?

Back

Gene expression controls the production of proteins that determine cell function.

Front

What is the function of messenger RNA (mRNA) in protein synthesis?

Back

mRNA serves as a template for assembling amino acids into a protein.

Front

What is the process of going from mRNA to a protein called?

Back

The process is called translation.

Front

What is the definition of transcription in genetics?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is the function of ribosomal RNA (rRNA)?

Back

rRNA forms the structural and functional core of ribosomes, where protein synthesis occurs.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the significance of the genetic code?

Back

The genetic code determines how sequences of nucleotides in DNA are translated into amino acids in proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
