Gene Expression 1 (Intro)

Front

What are regulatory genes?

Back

Regulatory genes are genes that regulate the expression of other genes, controlling cell function.

Front

What is a triplet codon?

Back

A triplet codon is a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule.

Front

What is a genome?

Back

The genome is the complete set of DNA in an organism, containing all of its genetic information.

Front

What is the primary genetic material in cells?

Back

The primary genetic material contained within cells and in nearly all organisms is DNA.

Front

What is the difference between a genome and a gene?

Back

A genome is the complete set of DNA in an organism, while a gene is a segment of DNA that codes for a protein.

Front

What role do proteins play in gene expression?

Back

Proteins perform various functions in the cell, including acting as enzymes, structural components, and regulators of gene expression.

Front

What is transcription in gene expression?

Back

Transcription is the process by which the information in a gene's DNA is transferred to messenger RNA (mRNA).

Front

What is translation in gene expression?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to synthesize proteins.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What are exons and introns?

Back

Exons are coding regions of a gene that are expressed, while introns are non-coding regions that are removed during RNA processing.
