Answer:
Option B, Transcription that originates at the core promoter and +1 site
Explanation:
In basal transcription process a special class of transcription factors which are nothing but the protein that binds to specific sites on DNA (which are also known as promoter sites) with an objective of activating transcription of genetic information from DNA to RNA , specifically messenger RNA. The transcription initiation requires association at promoter site(or regions of DNA that are found in the upstream of the coding region of a gene) along with a σ sub unit
Hence, option B is correct
Answer:
complementary base pairing
Explanation:
There are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds. They always pair up in a particular way, called complementary base pairing: thymine pairs with adenine (T-A)
The best answer among the following choices provided would be the third option C) He needs to use a larger sample size because if he uses a bigger size than the more soil and water can make a bigger/better tree.
