Front

What is the relationship between mRNA and DNA during transcription?

Back

mRNA is complementary to the DNA strand.

Front

Why do nerve cells and muscle cells function differently despite having the same DNA?

Back

Different genes are expressed in nerve cells and muscle cells.

Front

What does semiconservative replication mean in the context of DNA?

Back

The new DNA strands consist of one parent strand and one new daughter strand.

Front

What is a catalyst in biochemical reactions?

Back

A catalyst is a substance that speeds up a chemical reaction.

Front

What biomolecule do sugars and starches belong to, and what effect do they have on blood sugar levels?

Back

Sugars and starches are carbohydrates, and they increase blood sugar levels.

Front

What is the primary function of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.
