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:
Option. A) 12
Explanation:
An organism with 24 chromosomes in each body cell will produce sex cells with 12 chromosomes. The chromosome number is half because meiosis occurs in sex cells in which parent cell is divided into four daughter cells having half number of chromosome i. e. haploid. So the parent cell has 24 chromosome when division occurs, the number of chromosome becomes half i. e. 12.
This question is supposed to have a table showing species member tested and the type of cells tested and the results. Based on this table, the species member that would be unlikely to pass the gene mutation on to its offspring is species member 4: [Body cells (+) and Sperm (-)] Hope this helps.
