Unit 3B Review (DNA/RNA Processes, Mutations, Biotechnology)

Front

What does 'transgenic' mean?

Back

An animal that has DNA from another organism spliced into its genome.

Front

Why are insertion and deletion (frameshift) mutations harmful?

Back

They change all of the codons from the mutation on down the line, which changes the amino acid sequence.

Front

What was the main goal of the Human Genome Project (HGP)?

Back

To determine the entire sequence of human DNA.

Front

What is true about RNA compared to DNA?

Back

RNA is single-stranded.

Front

Where does transcription occur in a eukaryotic cell?

Back

In the nucleus.

Front

What is the role of DNA in living organisms?

Back

DNA stores genetic information that guides the development and functioning of living organisms.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is biotechnology?

Back

The use of living organisms or their products to modify human health and the environment.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose, while RNA is single-stranded and contains ribose.

Front

What is a codon?

Back

A sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
