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
Answer:
50% green-seed individuals vs. 50% yellow-seed individuals.
Explanation:
Mendel is known as father of genetics. He explained the concept of dominance, the law of segregation and the law of independent assortment while working on pea plant.
Green seed color is recessive and yellow seed color is dominant. A pure green line seed plant (ss) is crossed with heterozygous plant (Ss). The cross is as follows:
Parents ss (green seed) × Ss (Yellow seed)
Gametes s S, s
progeny: Ss, Ss, ss, ss.
Here, Ss is yellow seed and ss is green seed.
50% green-seed individuals vs. 50% yellow-seed individuals are formed after the cross.
Thus, the correct answer is option (a).
