Attenuation is a type of regulation that can control

Biology
1 answer:
Firdavs [7]3 years ago
7 0

Attenuation is the regulatory mechanism to control gene expression or transcription.  Attenuation was first observed in trp operon of E.Coli bacteria (commonly found at guts of warm blooded animal).  E.Coli bacteria need tryptophan which is a kind of amino acid. The bacteria can either take tryptophan from environment or itself synthesize by using bio synthetic enzymes. These bio synthetic enzymes are encoded by five genes located next to each other which we called as trp operon.

When tryptophan levels are high, then the transcription of trp operon is controlled. This process is called Attenuation. In this process the RNA polymerase is prematurely stopped during transcription of trp operon which results in formation of short mRNA. Due to premature control such mRNA doesn’t gets encoded with tryptophan biosynthesis enzymes.

Attenuation is carried out when tryptophan level is high, so as to prevent unnecessary production of biosynthetic enzymes which are needed to make tryptophan.

Can you describe how the motion and relative positions of the Earth, the Moon, and the Sun affect tides?
Strike441 [17]
<span>"The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides. When the sun, moon, and Earth are in alignment, the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides."

Write three observations that could help you identify a fish.
Alex
The three observations that could help an individual in distinguising whether the organism is a fish or not is that it should live under water as fish can't survive without water, another thing is that it should laid eggs when it comes to giving birth because when it does not lay eggs but produces a living organism normally without an egg, it is considered to be a mammal and lastly, the appearance it possess such as having gils or fins.
