Gene Expression and Regulation

Front

What is the role of DNA in protein synthesis?

Back

DNA controls the production of protein in the cell.

Front

What is post-transcriptional control of gene expression?

Back

It includes processes like the removal of introns and splicing together of exons.

Front

How does RNA splicing affect gene expression?

Back

It generates multiple mRNA variants from a single gene.

Front

What amino acid does the codon UUA represent?

Back

Leucine.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA molecules carry amino acids to the ribosome.

Front

Define gene expression.

Back

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

Front

What is a codon?

Back

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

Front

What is the significance of introns and exons in genes?

Back

Introns are non-coding regions removed during RNA splicing, while exons are coding regions that are expressed.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What are transcription factors?

Back

Proteins that help regulate the transcription of specific genes by binding to nearby DNA.
