Biology Flashcard

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the instructions for making proteins.

Front

What enzyme is responsible for splitting open the DNA during replication?

Back

Helicase is the enzyme that splits open the DNA.

Front

What happens if an error is found during the cell cycle checkpoints?

Back

Apoptosis will occur.

Front

What type of molecule is a lipid?

Back

Lipids are a class of biomolecules that include fats, oils, and waxes.

Front

How many nucleotides are needed to code for an amino acid chain of 6 amino acids?

Back

18 nucleotides are needed (3 nucleotides per amino acid).

Front

What are the nitrogen bases of DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where proteins are synthesized.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints regulate the progression of the cell cycle and ensure errors are corrected.

Front

What is the basic structure of an amino acid?

Back

An amino acid consists of a central carbon atom, an amino group, a carboxyl group, and a variable R group.
