Answer:
transcription initiation
Explanation:
Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:
1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.
2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence
3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).
In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.
Answer:
No, coyote will not become the apex predator.
Explanation:
No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t
he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni
che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver.
If the gray wolf became extinct, the coyote population increases in that location due to no predator.
Chromosomes; chromosomes can mutate during the creation of the next generation with semen and the egg.
Switch to anaerobic respiration
Answer:
The technology that allows scientists to study the activity of many genes at once is a <u>microarray</u>.
Explanation:
A microarray is a laboratory tool which is used to detect the expressions of a thousand genes at a time and these are in the form of slides which are printed with thousands of tiny spots at a defined position, with each spot having a known DNA or a gene.
