Fall 2024 Final Exam Review

Front

What are enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What forms a protein?

Back

A protein is formed when amino acids bond together through peptide bonds.

Front

What is an allele?

Back

An allele is a different form of a gene that can exist at a specific locus on a chromosome.

Front

What happens to enzymes when heated to high temperatures?

Back

The shapes of the enzymes are altered or denatured, affecting their function.

Front

What process does mRNA occur during?

Back

mRNA occurs during transcription, where genetic information is copied from DNA.

Front

What is the role of amino acids in protein synthesis?

Back

Amino acids are the building blocks of proteins, linked together to form polypeptides.

Front

What is the function of ribosomes in cells?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into proteins.

Front

Define transcription in the context of genetics.

Back

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

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like heat or pH.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and stores genetic information, while RNA is single-stranded and plays a role in protein synthesis.
