Answer:

I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2

Explanation:

My name is CO2, and I started out as glucose from pure honey. I got eaten by a little child when I was two weeks old, and I had to go through the dreadful process of aerobic respiration in the child's body.

My glucose molecules were broken down into pyruvate, and I stayed that way  for a while, as I made my way to the mitochondria of the child's cells.  Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.

If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.

Which of the following BEST describes the kinetochore? the array of vesicles that will form between two dividingnuclei and give
GREYUIT [131]

Answer:

a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules

Explanation:

Kinetochores have  vvery important role in the cell division-mitosis.

During the metaphase of mitosis, spindle fibers attach to kinetochores. Some of the microtubules bind to kinetochore (kinetochore microtubules) while other don’t: they connect with the microtubules from the opposite pole, stabilizing the spindle.

During the anaphase, kinetochore microtubules pull chromosomes toward poles, helping the sister chromatids separate from each other.

In negative control of transcription by the lac operon, how does the presence of an inducer affect transcription?.
ss7ja [257]

If the inducer [allolactose] is present in the negative control then it will bind to the repressor decreasing its ability to bind to the operator due to which the transcription begins again and the operon is turned on.

Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.

An inducer is a molecule that has the ability to induce or activate the operon. ex- in the case of the lac operon, allolactose acts as an inducer.

A repressor is a molecule that will repress or restricts the transcription of the genes of the operon, as a result, the operon will be switched off.

When the lac operon is under negative control, with no CAP [catabolite repressor protein] binding activity, the repressor remains active and thus binds to the operator region of the operon, as a result, no transcription takes place and the operon will be switched off.

But if the inducer will be present even in the negative control then the transcription takes place and the operon will be on.
