The correct answer is C because sometimes mutations are good and it helps organism to survive.
Answer:
The attenuation system would respond more to histidine (His) than to tryptophan (Trp) levels
Explanation:
In genetics, the attenuation system refers to the process of control which is responsible for triggering premature termination of transcription in bacterial operons. In bacteria, the process of attenuation is characterized by the presence of an attenuator, which is a stop signal sequence found in the leader mRNA. The tryptophan (trp) operon, which is a cluster of genes responsible to encode the components required during the production of tryptophan, is controlled by the attenuation system. When there is a high tryptophan level, the ribosomes are able to translate an attenuator sequence, thereby resulting in termination of transcription. The attenuation system also controls the synthesis of other amino acids including histidine (His), phenylalanine (Phe) and threonine (Thr).
They will be 100% heterozygous
It is false that u<span>nlike third-world and developing nations, the u.s. has no incidence of hungry or malnourished people.
You can find hungry people anywhere - even in the richest countries in the world. Not everyone has the same opportunities and living conditions, so it is only normal that there will be poor people who cannot afford even food.</span>
