CLONING-when you propagate an organism or cell as a clone they do this by removing a somatic cell such as a skin cell from an animal that they wish to copy they then transfer the DNA of the donor animals somatic cell into an egg cell

CLONING-they could also put the cell in an oocyte that has had its own DNA containing nucleus removed

GMO's-When a gene from one organism is purposely moved to improve or change another organism in a laboratory, the result is a genetically modified organism (GMO).

GMO's-It is also sometimes called "transgenic" for transfer of genes. There are different ways of moving genes to produce desirable traits.

adult vs embryonic stem cell research-Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. Embryonic stem cells can be grown relatively easily in culture.

dna fingerprinting and criminal investigation-The term DNA fingerprinting - or genetic fingerprinting - is applied to the scientific process whereby samples of DNA are collected, collated and used to match other samples of DNA, which may have been found at the scene of a crime.

we use dna fingerprinting because This process is used as one means of identification when an attacker or assailant has left some kind of bodily fluid or blood at the scene of a crime and when no visual identification is possible.

pcr and gel electrophoresis-Gel electrophoresis of PCR products is the standard method for analyzing reaction quality and yield. PCR products can range up to 10kb in length, but the majority of amplifications are at 1kb

electrophoresis yields a single strong band of correct size, as determined by comparison with size markers run on the same gel. If possible, identity should be confirmed by digestion with a restriction enzyme with a known site in the target DNA

plasmids-A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA.
