What is the process by which materials are engulfed by the cell membrane and brought into the cell?
The process by which materials are engulfed by the cell membrane and brought into the cell is called endocytosis. It involves the formation of vesicles that surround the material to be taken in and then fuse with the cell membrane to release the contents into the cell. There are two main types of endocytosis: phagocytosis, for larger solid particles, and pinocytosis, for smaller liquid particles.
Why are biotechnology companies interested in genetic information?
Biotechnology companies are interested in genetic information in order to use genectic modification to create modifications in DNA that result in new traits in an organism. For example, biotech companies have created crops that are resistant to herbicides like Glysophate, and ones that produce an insecticide within the plant itself. Pharmeceudical companies are interested in genetic information in order to use it to create new drugs.
Since patents can be obtained for the modifications, the companies make profits from them and also have the protection that for a number of years, no other company can use the patented changes.

What is the primary function of the Calvin cycle?
The primary function of the Calvin cycle is to convert carbon dioxide from the atmosphere into organic compounds, particularly glucose, which can be used by plants as an energy source and as building blocks for growth. This process occurs in the stroma of chloroplasts and is essential for photosynthesis.
The first animal ever cloned was a tadpole, back in 1952. Dolly was the name of the sheep that was the first mammal ever cloned. It was in 1996, presented to the world in 1997.
Would human clones have identical fingerprints?
nope, if what i understand is right, then no they don't.
The genetic content should be almost identical as long as the DNA repliction proof reading is 100% acurate, no translocations have taken place. The telomeres (on the ends of the chromosomes) will have shortened a little but this is noncoding DNA so is unimportant in protein expression. If there are any areas of damaged DNA the cell cycle should halt until it is repaired or undergo apoptosis (cell suicide). Anytime dude Diesal 'danger' nutkins
Where in the cell is genetic information stored?
Encoded by the DNA comprising the Genes which sit on the Chromosomes in the cells Nucleus. The genetic information in the cell is stored in the nucleus. the nucleus controls the cell and is like a little dot.
How does genetic mutation occur?
Gene mutations may occur in at least three Ways: they can be inherited from a parent, or acquired during a person's lifetime - See Epigenetics - or acquired during a person's lifetime - see Strontium 90.
Where were the first cloned plant cloned?
A vast number of plants clone themselves naturally. The ability goes back hundreds of millions of years.
How do captive breeding programs affect genetic diversity?
Captive breeding programs can affect genetic diversity in one of two ways. Within the program itself, genetic diversity is reduced, because captive breeding programs only have a limited number of animals to work with. On the other hand, animals from a captive breeding program that are re-introduced to the wild can increase genetic diversity, because they are bringing genes that may have been gone for a long time back into the gene pool.
What is Genetically programed behavior?
Theta, Gamma, Al-fa waves that can be stimulated with brain entertainment programs. To induce genetically programmed behaviour and other subconscious thoughts that can be entrained and enhanced. Yes? or No?
What is another way that sexual reproduction results in genetic recombination?
Parent AA and Parent aa have children. All children are Aa
Parent Aa and Parent Aa have children. 1AA:2Aa:1aa probability with each child.
This is recombination of the most direct/simplest kind.
What is the difference between a genetic disorder and a genetic mutation?
A genetic disorder is something an individual is born with, and results from a problem within their genetic material. This means they have inherited the disease or disorder from their Mother or Father. You cannot inherit an infectious disease, you acquire it during your lifetime from a germ, such as a virus or a bacterium. You can also recover from an infectious disease, whereas you will always suffer from a genetic disorder if you inherit one.
What are some uses of genetic engineering?
With genetic engineering you could create cures for certain diseases or even a healthier population that is not susceptible to diseases. You might also be able to change the world's food supply by designing food that is pest and drought resistant.
What are the steps of using recombinant DNA technology?
1 Isolate DNA
2 Cut DNA with a restriction enzyme
3 Mix the DNA's and join then together by using DNA ligase
4 Insert the recombinant plasmid into a host bacterium
5 Allow the bacterium to reproduce
- Human cells,from the individual who will be cloned.
- Media in which these human cells will grow and divide.
(breeding oven)
- Media in which cells will stop dividing, and enter a state
of "quiescence" without dying.(freezer)
- Laboratory supplies: Incubator, Sterile Hood, petri dishes,
microscopes, and tools capable of removing and implanting
cellular organelles,from one cell to another.
- Unfertilized human egg cells.
- Media in which the fertilized eggs can grow and
step 2Commence cloning!This first step is easy: You only need to grow the cells until you have the amount you want.The second step isn't hard either: Transfer the cells to the freezer. This should allow the cells to live, but they should stop dividing and enter quiescence.
The third step is a hard one for the unexperienced cloner: When the cultured cells are in the quiescent state, get an unfertilized human egg cell. Remove the nucleus from this egg cell. Try to minimize damage done to this cell and discard the nucleus, because this has become useless now.
The forth step is a rather difficult one too:
Take one of the quiescent cells in it's entirely, and implant it inside the coat around the egg (known as the zona pellucida, if you really want to know) next to the egg itself.
The fifth step isn't as hard as step 3 or 4: Electroshock the egg. The electroshock induces the fusion of the two cells, so you should be able to tell when you've electroshocked enough just by looking at the cells.
The sixth (and last)step: Repeat the last three steps as necessary until you have enough clones. Expect a lot of them not to survive because of cellular damage and other mishaps. Allow the embryos to grow and divide a few times in Human Egg Cell growth media. Now implant the embryos in human mothers where they can be carried to term, and born normally. After a few months (approximately 9) you have your own child :) divide
step 3Legal stuffCloning is illegal in the following countries:*USA
*UK
*All of the European Union
*Australia
*the UN is against cloning, but doesn't force their members to
abolish it
...
So it is not allowed to make a real clone (which renders this Instructable useless XD).
When you really want a child, I suggest you find yourself a wife/man and do it the traditional way (which I personally find to be more fun:P)
This instructable is made for entertainment only, please don't try this at home.
What is t a c g c c g t g g t t c g a t c?
t a c g c c g t g g t t c g a t c is an example of a DNA code. inside each cell in your body there is a doublr helix of DNA Each small circle is one of four componets adenine (represented by A), guanine (represented by G), cytosine (represented by C) and thymine (represented by T). These are writted together to represent DNA
When was the first plant cell discovered?
It was discovered by Robert Hooke in 1678 that cork, when sliced into a small piece and put under a microscope that their where little box-like compartments which are now known as "cells" Robert Hooke opened a whole field of science for the rest of mankind.
How and why does cloning of plants differ from cloning of animals?
vegatation reproduction dont produce clones man. im not lying no joke mate lol. seriously why would you think im lying
