What is DNA gene expression?

Back

The process by which information from a gene is used to synthesize a functional gene product, typically a protein.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation to assemble proteins.

Front

What is a frameshift mutation?

Back

A mutation that results from the insertion or deletion of nucleotides, causing a shift in the reading frame of the genetic code.

Front

What is an insertion mutation?

Back

A type of mutation where one or more nucleotide bases are added to the DNA sequence.

Front

What is a deletion mutation?

Back

A type of mutation where one or more nucleotide bases are removed from the DNA sequence.

Front

What is a substitution mutation?

Back

A mutation that replaces one nucleotide base with another in the DNA sequence.

Front

What is the function of mRNA in protein synthesis?

Back

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

Front

Why is transcription important?

Back

Transcription is necessary to create mRNA from DNA, allowing the genetic information to be translated into proteins.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, assembling amino acids into proteins based on mRNA sequences.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA corresponds to the sequence of amino acids in proteins.
