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)
There are steps you must follow in the making of recombinant DNA such as use crosses to identify donor, clone gene in bacterium, characterize the gene, modify the gene, and reintroduce the gene into donor cells.
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.
A donor cell is a cell that a donor donates for genetic research.
If it's a blood donor, you don't need to. BMBP'S REPLY-I accept but we are talking about bone marrow transplantation
yes

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
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.
Both would have to have closely matched DNA and the one getting the hair would have to take immune suppressing drugs.

Sort of... Assuming there is no GVHD and the bone marrow transplant is successful, a blood test will show what percent of the recipient's blood is their own blood and what percent of the recipient's blood was produced from the donor's bone marrow. If the test comes back ">95%", then the recipient's blood and the donor's blood have become DNA-identical. Interestingly enough, the recipient's hair and saliva remain the same DNA they were born with. Their hair and saliva do NOT change to the donor's DNA. So, the recipient of the bone marrow transplant would then have two DNA's in their body. Neat stuff!
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.
