mariarad [96]

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.

Which one of the following is NOT an example of microbial antagonism?
snow_lady [41]

Answer:

e. bacteria producing vitamin K

Explanation:

Microbial antagonism basically refers as microbes versus microbes i-e the indigenous microflora serve a beneficial role by preventing other microbes from becoming established in or colonizing a particular anatomic location in the body.

As all the options mentioned, refers to the microbial antagonism except option E as the normal microbes protect the host by :

1) Producing acids.

2) Bactreocin production

3) By occupying the niches that the pathogens may occupy.

But the microbes cant compete with other microbes by  producing vitamins and growth factors that can be utilized by the host.

Hence option E is the right answer.
