Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

What amino acid does the codon ACG code for?

Back

Threonine (Thr)

Front

What process is occurring when mRNA is synthesized from DNA?

Back

Transcription

Front

What is a gene?

Back

A gene is a segment of DNA that contains the instructions for making a specific protein.

Front

Where does transcription occur in a cell?

Back

In the nucleus.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins from amino acids.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

True or False: A mutation always causes a negative consequence.

Back

False. Some mutations can be neutral or even beneficial.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of making RNA from DNA, while translation is the process of making proteins from RNA.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.
