It is necessary for the gene that codes for the repressor of lac operon to be near the structural genes. True or false

Biology

Dima020 [189]4 years ago
7 0

Answer:

FALSE!!!!!!

Explanation:

Lacl is the name of the gene that encodes the lac repressor. It undergoes continuous transcription to make the lac repressor always present.

Even though It happens to be found near the lac operon, it is not a member of the operon and is expressed separately. Therefore, it is not necessary for it to be near the structural gene

Which of the following best explains a characteristic that differentiates Fungi from Plants?
NikAS [45]
<span>The answer is C because fungi use decomposition to get nutrition, while plants produce their own nutrients, making them autotrophs.

Movement of the chromosomes during anaphase would be most affected by a drug that
My name is Ann [436]

Answer:

The options are missing, the options are:

A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation

The answer is C

Explanation:

Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.

Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.

A nerve poison that blocked neurotransmitter receptors on the dendrites would __________. inactivate the enzyme that degrades th
Svet_ta [14]

The correct answer is: prevent reception of a signal in a receiving neuron

Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.

Drugs that bind to neurotransmitter’s receptor can have two effects on its action:

• Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it

• Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).

The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of?
kogti [31]

The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of ​LDL.

  • The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque.
  • The build-up of lipids and fibrous components in the major arteries is a hallmark of the degenerative illness known as atherosclerosis. A picture of a typical artery's anatomy can be found in Foam cells, or subendothelial accumulations of cholesterol-engorged macrophages, are the earliest lesions of atherosclerosis.
  • Nitric oxide and prostacyclin are two chemicals that are produced by your endothelium. These maintain the fluid in your blood and stop it from clotting when it shouldn't. These compounds' insufficient production is a symptom of various diseases, which raises your risk of clotting.
