DNA, DNA Replication, and Protein Synthesis

Front

What are the three components of a nucleotide?

Back

Nitrogen base, sugar, and phosphate.

Front

What is the role of DNA in cells?

Back

DNA stores genetic information and provides instructions for protein synthesis.

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

When does DNA replication occur in the cell cycle?

Back

Before cell division.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.

Front

What are the types of mutations?

Back

Substitution, insertion, deletion, and frame shift.

Front

What is an insertion mutation?

Back

A mutation where extra base pairs are added into a DNA sequence.

Front

What is the function of mRNA?

Back

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

Front

What is the central dogma of molecular biology?

Back

DNA -> RNA -> Protein.

Front

What is recombinant DNA technology?

Back

A method used to combine DNA from different sources, often used to produce human hormones.
