What is the function of restriction enzymes in the process of DNA recombination?
First, a specific enzyme is needed to cut the DNA from the donor genes at a specific site. This enzyme is called a restriction enzyme.The enzyme is used to cut out a piece of DNA that contains one or more desired genes from the donor's DNA. Next, a vector is needed to receive the donor DNA. Most frequently, a naturally occurring circular piece of bacterial DNA, called a plasmid, is used for this purpose. Finally, an enzyme is used to "stitch" the donor DNA into the plasmid vector. This enzyme is called ligase, and it creates permanent bonds between the donor DNA and the plasmid DNA. The result is that the donor DNA is incorporated into the bacterial plasmid, forming the recombinant DNA (rDNA)
What is the role of the Egg cell donor.?
A donor cell is a cell that a donor donates for genetic research.
How do you combine male DNA with female DNA?
When gametes meet - at conception the DNA is combined. The male gamete (sperm) carries DNA from the male, and the female gamete (ovum) carries DNA from the female. Male and female DNA are combined during sexual reproduction.
Does the DNA differ from male and female?
Yes
Why clone always resembles with nucleus donor parent only?
Clones resemble the nucleus donor parent because the cloning process involves transferring the nucleus of a somatic cell from the donor into an enucleated egg cell. This nucleus contains the complete genetic material of the donor, which dictates the organism's traits. As a result, the clone inherits the DNA of the donor parent, leading to physical and genetic similarities. Environmental factors may influence some traits, but the genetic blueprint remains consistent with the nucleus donor.
Is it necessary to take the DNA test of the donor in case his bone marrow is taken for transplantation?
If it's a blood donor, you don't need to. BMBP'S REPLY-I accept but we are talking about bone marrow transplantation
Male present in female of body is known as?
A male present in the body of a female is known as microchimerism. This occurs when a small number of cells or DNA from a male fetus or male donor persist in a female's body. This phenomenon can happen during pregnancy, organ transplantation, or blood transfusions.
Do transplanted organs forever keep the DNA of the donor?
yes
How is cloning possible?
Alright, please disreguard the other "answer". They take a DNA sample from the organism that is to be cloned. Then they take an embrio from an animal the same species as the animal that will be cloned. Then they extract DNA from the embrio and replace it with the DNA sample from the animal that's going to be cloned. Then they place it back in the womb or uterus of the animal the embrio belongs to. It's not really cloning like what you see on the science fiction channel, that's why it's science fiction.

When someone gets a blood transfusion don't they have the donor's DNA in their bloodstream for awhile?
Red blood cells lack a nucleus so they don't have chromosones, however they do have mitochondrial DNA from the donor. http://www.answers.com/topic/erythrocyte
Is it possible to determine the sex of a cell donor by examining the cell?
Yes, by examining the DNA of the cell, you will be able to determine if the donor was male (XY) or female (XX) based on the sex chromosomes. You will not be able to determine the sex of the donor by the appearance of the cell - the only way is to determine what sex chromosomes are present. Unless the cell is a sex cell, in which case sperm cells are easily distinguished from ovum/eggs.
Is it possible to get a hair transplant from a different donor than myself?
Both would have to have closely matched DNA and the one getting the hair would have to take immune suppressing drugs.
What is the role of the Egg cell donor.?
A donor cell is a cell that a donor donates for genetic research.
When a person is a male then changes to female does the DNA change also?
nope,, his dna is still male dna because dna is unchangeable even if he change his genital. that's why dna can be used to identify an individual.

What is the purpose of the egg cell donor in cloning?
The egg cell donor in cloning provides the genetic material necessary for the creation of a clone. The nucleus of the donor egg cell is usually removed and replaced with the DNA of the individual being cloned, initiating the development of a genetically identical organism. The egg cell provides the necessary environment for the DNA to develop into a new organism.
