Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

Answer:
measels is caused by a single stranded Rna virus of the family Paramyxoviridae
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.
Hope this helps
