What is the theory behind western blotting?

A western blot is done by immobilizing cellular proteins on a thin membrane (usually PVDF or nitrocellulose) and detecting them with antibodies to specific proteins.

Briefly, cells are lysed, proteins are resolved on a gel, then proteins are transferred to a membrane, and finally the proteins are detected by enzyme-conjugated antibodies.

Why is genetic engineering an important development?

Since genetic engineering involves the manipulation of genes, genetics is the utmost importance in genetic engineering or any form of genetic technology. The knowledge of the genetics must be present for experiments to work.

Why is human cloning unsafe?

If something goes wrong, it could turn out all deformed and be kind of like an evil scientist project or something. The person or animal can go through mental problems, depression, etc. Plus think about this: Imagine you seeing yourself growing up and doing the things you use to do as a kid. Cloning is just crazy and stupid. Then the scientists or whatever could use the clones for bad things who knows.. But I think cloning is whack. Lol!

How are bacteria being used in genetic engineering to produce medicine for people?

  1. They do yo mam
  2. They get ho preggo
  3. She has da babey
  4. You da babay dadday
  5. you murder the babyy
  6. You spend yo lyfe in prison, only to escape in 2020

What condensed genetic materials or chromatin that is double stranded?

Condensed genetic material or double stranded chromatin is a chromosome. Chromosomes are long strands of DNA tightly wrapped around histone 'beads' which help to pack it down to fit within the cell. The cells of your body are absolutely tiny, but inside every one of them is close to 2 metres of DNA, so it's absolutely necessary to pack it down as small as possible. The tight structure of chromosomes allows for this, and also aids in making mitosis simpler for the cell.

Are there been any new genetic treatments to treat progeria?

There is no treatment for progeria. That is genetic aberration and not a disease.

Why are genes and DNA called the language of life?

The Blueprint of Life Every cell in your body has the same "blueprint" or the same DNA. Like the blueprints of a house tell the builders how to construct a house, the DNA "blueprint" tells the cell how to build the organism. Yet, how can a heart be so different from a brain if all the cells contain the same instructions? Although much work remains in genetics, it has become apparent that a cell has the ability to turn off most genes and only work with the genes necessary to do a job. We also know that a lot of DNA apparently is nonsense and codes for nothing. These regions of DNA that do not code for proteins are called "introns", or sometimes "junk DNA". The sections of DNA that do actually code from proteins are called "exons".

How are mutations connected to evolution?

Evolution is defined as genetic change inherited by offspring. The study of genetics and population genetics provides insight into the mechanisms of evolution.

What about the degenracy of genetic code?

Type your answer here... the degenracy of code means there are more than one codons for one amino acid.The opposite of it ie.non-degeneracy of codon means ther is only one codon for one amino acid.

During transcription the genetic information is rewritten as a molecule of?

During transcription, the genetic information is rewritten as a molecule of

What characteristic is often genetically engineered in crop plants?

By far the characteristic that is most often genetically engineered into crop plants is resistance to herbicides, with engineering crops to produce a substance that kills insects into the plant itself a close second.

How can scientists use plastids to transfer characteristics from one organism to another?

A plasmid is a circular double stranded DNA usually found in bacteria. Most of them do not have specific functions and altering them does not hamper the bacteria possesing them. A gene of interest can be annealed to this plasmid so as to make the concerned bacteria produce a particular product. Since the bacteria can now produce a new product, the plasmid has been used to alter the characteristics of the organism.

What are Professionals who help couples understand their chances of having a child with a particular genetic disorder are called?

A professional who helps people understand their chances of having a child with a genetic disorder is called a geneticist.

What kind of diseases are the most common genetic diseases For example those in which both parents may be carriers of the disease without knowing it because they don't actually have the disease?

What kind of diseases are the most common genetic diseases? (For example, those in which both parents may be carriers of the disease without knowing it because they don't actually have the disease.)

How cloning works?

1

Eggs are coaxed to mature in a culture dish. Each has a remnant egg cell called the polar body and cumulus cells from the ovary clinging to it. 2

While an egg is held still with a pipette, a needle is used to drill through the zona pellucida, removing a plug. 3

After ejecting the zona plug, the needle is inserted back in the egg through the hole to withdraw and discard the polar body and the egg's genetic material. 4

A cumulus cell from another egg is taken up into the needle. Cells called fibroblasts (or their nuclei) can also be used in this step. 5

The cumulus cell is injected deep into the egg that has been stripped of its genetic material. 6

The injected egg is exposed to a mixture of chemicals and growth factors designed to activate it to divide. 7

After roughly 24 hours, the activated egg begins dividing. The cells contain genetic material only from the injected cumulus cell. 8

By the fourth or fifth day, a hollow ball of roughly 100 cells has formed. It holds a clump of cells called the inner cell mass that contains stem cells. 9

The blastocyst is broken open, and the inner cell mass is grown in a culture dish to yield stem cells. 10

The stem cells, in turn, can be coaxed to grow into a variety of cells that might one day be injected into patients.

Chromosomes line up along in the equator not in homologous pairs?

Metaphase. What's the difference? Whether it's IN homologous or NOT, they're both Metaphase..... Stupid worksheet. I hate you group 3. :(

Genetic material must be able to?

it must be able to produce complete working proteins, have the ability to adapt to changes, to reolicate faithfully and they must allow for evolutionary change

What is the number of nuclei in a zygote?

a zygote is a fertilized egg. one that has formed by the fusion of an egg cell and a sperm cell
