Answer:
Negative inducible.
Explanation:
Operon may be defined as the cluster pf genes that are expressed by the single RNA polymerase. The operon includes in the example of the the polycistronic genes.
Negative inducible operon includes the binding of regulatory protein with the DNA and inhibits transcription. The regulatory protein binds with the operator that prevents RNA polymerase transcription. The mutation in the negative inducible operon prevents the binding of repressor to the small molecule.
Thus, the correct answer is option (a).
Answer:
Heterozygous
Explanation:
A genotype describes which alleles of a particular gene a person has. We have two copies (alleles) of each gene, one from mom and one from dad, but these alleles can be different.
Often, these alleles can be dominant and recessive with regards to eachother. The dominant allele will always be displayed in the phenotype, whereas the recessive will not be presented, as it is masked by the dominant gene. If you have two copies of the dominant gene (homozygous) you will display the phenotype associated with the dominant genotype. If you have two copies of the recessive gene (homozygous) you will display the phenotype of the recessive gene.
If you have one copy of each (heterozygous), you will display the phenotype of the dominant gene, even though your genotype has a copy of each.
