The term is used notably for non-viral methods in eukaryotic cells. It may also refer to other methods and cell types, although other terms are preferred: "transformation" is more often used to describe non-viral DNA transfer in bacteria, non-animal eukaryotic cells and plant cells.

The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase.
It is actually the first pyrimidine that was successfully purified by scientists from an all natural source in 1893 – 1894.

Human immunodeficiency virus (HIV) is a lentivirus (a member of the retrovirus family) that causes Acquired Immunoeficiency Syndrome (AIDS), a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk.

In molecular biology and genetics, mutations are changes in a genomic sequence : the DNA sequence of a cell's genome or the DNA or RNA sequence of a virus.
They can be defined as sudden and spontaneous changes in the cell. Mutations are caused by radiation, viruses, transposons and ridu's Deathzzhttp://www.blogger.com/profile/16191550467030937250noreply@blogger.com1tag:blogger.com,1999:blog-7837116550549260225.post-36155747450336145762011-06-16T20:30:00.000+07:002011-06-16T20:30:55.984+07:00DNA and RNADNA and RNA are two different nucleic acids found in the cells of every living organism. Both have significant roles to play in cell biology. DNA and RNA structure are similar because they both consist of long chains of nucleotide units. However, there are a few structural details that distinguish them from each other, and if you are to compare DNA and RNA, these would be the results:

It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living things depend on genes, as they specify all proteins and functional RNA chains. Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring, although someridu's Deathzzhttp://www.blogger.com/profile/16191550467030937250noreply@blogger.com0tag:blogger.com,1999:blog-7837116550549260225.post-13892532990689897222011-06-02T18:39:00.001+07:002011-06-02T18:42:17.433+07:00about DNADNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.
