Eukaryote Genes: Human Beta-Globin Genes

These flashcards cover key vocabulary and concepts related to eukaryotic genes, specifically human beta-globin genes, their structure, expression, and development.

Eukaryote

Organisms whose cells have a nucleus enclosed within membranes.

Beta-Globin

A component of hemoglobin that binds oxygen, important for red blood cell function.

Heterotetramer

A protein structure composed of four polypeptide chains, in this case, two alpha-globins and two beta-globins.

Hemoglobin

An oxygen-transporting protein found in red blood cells, consisting of globin polypeptides and heme groups.

Cluster

A group of similar genes located close together on a chromosome.

Pseudogene

A non-functional gene that resembles a functional gene but has mutations preventing its expression.

Intron

Non-coding segments of a gene that are removed during RNA splicing.

Exon

Coding segments of a gene that are expressed and translated into proteins.

Locus

The specific physical location of a gene on a chromosome.

Gene Duplication

A process by which a segment of DNA is copied, resulting in two copies of that segment.

Zeta-Globin

A type of globin protein that can substitute for alpha-globin in hemoglobin.

Epsilon-Globin

A type of globin protein normally expressed during early embryonic development.

Gamma-Globin

A globin protein that is abundant in fetal hemoglobin, allowing for higher oxygen affinity.

Delta-Globin

A type of globin protein that can replace beta-globin in adult hemoglobin.

Transcription Regulation

Process by which the expression of genes is controlled, influencing when and how much protein is made.

Heme Group

An iron-containing molecule that binds oxygen, found within the hemoglobin protein.
