Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
The correct answer is Robert Hooke.
The invention of the microscope is one of the most essential discoveries ever made by the scientists. Robert Hooke in 1965, witnessed a slice of thin cork beneath the microscope and witnessed minute spaces, which appeared like small rooms combined together.
As they appeared like the tiny quarter of prisoners or monk he named the structures as cells.
This was Scientist Hooke... he was once in jail and that may have been one of the reasons he made the connection to the cells shape and called them what they are today :)
lol we just learned this biology earlier this week and I'm so proud of myself that I remember :)
A hydrogen bond is the electrostatic attraction between polar groups that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F) experiences attraction to some other nearby highly electronegative atom.
