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).
Answer: it's kind of options a and d together. A tumor is an abnormal mass doesn't serve any function and it results from an excessive cell division
DNA is semiconservative because during replication, it separates into two strands. It then recreates the opposite strand on each of the original strands to form two new identical strands of DNA. It's not conservative because it does not recreate a whole new strand off of one whole original strand.
Answer:
c. urostyle
Explanation:
Urostyle is the given name to the particular structure involving the last group of vertebrates which are fused in a single posterior bone in amphibians.
If you compare melting or boiling point with respect to the atomic number, you will found that the melting/boiling point will be <span>higher </span>as the atomic number increases.
But after a few point, you will see that it will be decreased and become lowest when it hit the noble gas. After that, the melting point will be increased again and then decreased again at same pattern.
