Pro vs. Eu, Cell Cycle, & DNA Flashcard

Front

What determines the code of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

The organization of the genetic material.

Front

What is the process of transcription?

Back

Transcription is the process where double-stranded DNA unwinds and is used to create mRNA.

Front

What is the product of transcription?

Back

mRNA (messenger RNA).

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can affect genetic information.

Front

What is a silent mutation?

Back

A silent mutation is a change in the DNA sequence that does not alter the amino acid sequence of the protein.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one base is replaced by another in the DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more bases are removed from the DNA sequence.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more bases are added into the DNA sequence.

Front

What is the role of mRNA in gene expression?

Back

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