Many useful products, mainly for medical purposes, are produced by cloning human genes into other organisms, which then mass-pro

ANEK [815]

Answer:

The correct answer is : A.

Explanation:

This is because of the following reasons:

Escherichia coli is a bacteria and hence is a prokaryote.
The cloning of human (eukaryote) genes is done to obtain in-vitro protein expression which are to be used a pharmaceutical compounds.
Although the phenomenon of Central Dogma takes place in both Prokaryotes and Eukaryotes, the mechanism is very different.
Some of the differences includes:

Eukaryotic genes contain certain non-protein encoding sequences called the Intron sequences which needs to be removed from the transcribed mature mRNA by Spliceosome. This phenomenon is absent in prokaryotes as they do not possess introns. Hence, proper processing of eukaryotic mRNA is not possible in prokaryotes.
The mature eukaryotic mRNA has a 5' cap and 3' polyadenylated tail which is added by a capping enzyme and a poly-A polymerase enzyme to increase their stability. This will not be possible in a prokaryote as they lack these enzymes.
The translation of membrane proteins and secretory proteins is carried on by the ribosomes bound to the endoplasmic reticulum. This structure is absent in prokaryotes, hence they will be unable to produce a proper polypeptide sequence.
Finally, the eukaryotic proteins undergo various modifications after formation, like methylation, acetylation, etc. These reactions cannot be carried out in a prokaryote as they lack the respective enzymes.
Hence, we see a properly folded functional eukaryotic protein cannot be produced in a prokaryote.

What's mitosis and meiosis?

jeka57 [31]

Answer:

<h3>MITOSIS AND MEIOSIS*</h3>

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

<h3>What meiosis means?</h3>

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

<h3>What is mitosis explain?</h3>

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

<h3>What is meiosis important?</h3>

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

<h3>What is Mitosis important?</h3>

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

<h3>What is Mitosis means?</h3>

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). ... The major purpose of mitosis is for growth and to replace worn out cells.

<h3>What Meiosis explain?</h3>

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins following one round of DNA replication in cells in the male or female sex organs.

The element nitrogen has the atomic number 7 and an atomic mass of 14. How many neutrons does an atom of nitrogen contain?

arsen [322]

It would contain 7 neutrons. To find how many neutrons any element has, simply take the atomic mass and subtract the number of protons (atomic number) front that.
