Biology Semester 1 MEGA Review

Front

What is helicase?

Back

Helicase is a protein that unwinds the DNA double helix during DNA replication.

Front

What process occurs when particles move from high concentration to low concentration?

Back

Diffusion is the process where particles move from areas of high concentration to areas of low concentration.

Front

What is the function of mRNA?

Back

mRNA provides information from DNA to ribosomes for protein synthesis.

Front

What happens to body temperature when exposed to cold?

Back

Body temperature decreases, causing shivering to increase body temperature.

Front

What occurs to an enzyme when it is denatured?

Back

When an enzyme is denatured, it loses its shape and functionality.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating mRNA.

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store and transmit genetic information.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
