gene expression

Front

What determines the unique properties of a cell?

Back

The genes expressed in the cell.

Front

At which step does most gene regulation occur?

Back

Transcription.

Front

What is the protein that packs DNA into chromosomes?

Histones.

Front

What is the name given to a part of a DNA molecule that codes for a protein?

Back

Gene.

Front

What binds to the operator to shut off gene expression?

Back

Repressor.

Front

What is the process by which DNA is copied to RNA?

Back

Transcription.

Front

What is the role of mRNA in gene expression?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of ribosomes in protein synthesis?

Back

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

Front

What is the difference between an intron and an exon?

Back

Introns are non-coding regions of a gene, while exons are coding regions that are expressed.

Front

What is the role of transcription factors in gene expression?

Back

Transcription factors are proteins that help regulate the transcription of specific genes by binding to nearby DNA.
