Answer:
A. The DNA-bending function of TBP cannot be performed by another protein in the general transcription factor complex.
Explanation:
TATA box sequence binding protein binds to aspecific region on DNA known as TATA Sequence. TATA binding protein binding to the DNA Sequence is necessary because it generates <em>bending of DNA till 80° angle.</em>
<em></em>
BINDING of all transcription factors depends solely upon the binding of TBP directly, that is why TATA binding proteins bonding to DNA is very important for initiation of transcription. Any other protein does not have the capacity of band formation with DNA. Hence, A. the DNA-bending function of TBP cannot be performed by another protein in the general transcription factor complex.
Answer: (1) The populations breed separately.
Explanation:
The genetic diversity can be define as the total number of different types of genes is present in a particular species. Genetic diversity makes the way suitable for the survival of the population of species in changing environment.
According to the given situation, if the two population breed separately then then no new genes will be added to the gene pool of the species and hence, the genetic diversity will be lost.
