VLD [36.1K]

Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid. A diploid means containing the normal amount of chromosomes. This is the result of DNA replication and 1 cell division. ... Meiosis is used to produce gametes which are sperm and egg cells, the cells of sexual reproduction.

What does the operon model attempt to explain?
sergiy2304 [10]

Answer:

a. the coordinated control of gene expression in bacteria

Explanation:

An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.

Operons allow organisms to control the expression of multiple genes in response to environmental cues
