Which region of the operon does the repressor bind to?

Biology
1 answer:
Llana [10]3 years ago

Answer:

To the operator of the operon

Explanation:

A repressor binds to the operator of the operon. This blocks the attachment of RNA polymerase to the promoter, preventing transcription of the genes.

You can see the different elements of the operon and the region where the repressor binds in the image below (lac-operon):

Allisa [31]

Transposable elements and short tandem repeats are different because short tandem repeats make up only a small percentage of a given genome while transposable elements often make up larger parts of a genome. So the correct option is C.

<h3>What are transposable elements? </h3>

Transposable elements or transposons are a class of genetic elements. They can  “jump” from one location to another, in a genome.

Even though they are called “jumping genes,” they have an integrated site in a genome and are maintained there. Also, most of them are eventually inactivated and can not move any longer.

Whereas Short tandem repeats or STRs are short repeats of DNA. They are also known as microsatellites or simple sequence repeats. They have a repetitive unit of 1-6 bp and form a series of 100 nucleotide lengths.

Therefore the correct option C.

Softa [21]

Answer:

Electrical>thermal>light

Explanation:

Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.

Thermal energy on the other hand refers to internal energy of a system where temperature is constant.

Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.

Therefore, the energy transformation taking place according to the question is option D.
