Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What amino acid does the codon AGG code for?

Back

Arginine.

Front

What is a GMO?

Back

A GMO (Genetically Modified Organism) is an organism whose DNA has been altered by humans to exhibit desired traits.

Front

What is the product of DNA replication?

Back

The product of DNA replication is two identical strands of DNA.

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in the DNA sequence.

Front

What are the types of point mutations?

Back

The main types of point mutations are missense, nonsense, and silent mutations.

Front

What is a missense mutation?

Back

A missense mutation is a point mutation that results in the substitution of one amino acid for another in the protein.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a point mutation that creates a premature stop codon, leading to a truncated protein.

Front

What is a silent mutation?

Back

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