F1 stands for first generation in Mendels experiment
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:
water covering earth surface is 71 percent. e 97 percent. frozen freshwater less than 1 percent
Explanation:
ok
Let's call the colour alleles C for dominant purple, and c for recessive white.
We have crossed Cc with Cc. So if we put that in a Punnett square, we'd have a CC, two Cc and a cc. That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)
