If you would like to get in the field of forensic science, you must take a heavy concentration of science courses including biology, chemistry, and physics. Computer skills are also very important, especially for finger print identifiers. A number of colleges provide programs in forensic science, pathology and other versions of forensic science...

from genes to proteins Proteins have many functions, including acting as enzymes and cell membrane channels. Proteins, however, are not built directly from DNA. Ribonucleic acid is also involved...	2 / 382
gene cloning Clone: A group of identical cells or organisms To clone a gene: 1) Insert the gene into a vector that can carry the into a host cell 2) Ensure that it will replicate there 3) Insertion is carried out by cutting the vector and the DNA to be inserted with the same restriction endonuclease to ensure that both have the same "sticky ends" Vector for cloning the bacteria come from two major types: (1) Plasmids, and (2) Phages Recombinant DNA Technology A) It was developed in 1970 B) Procedure: (1) Obtain DNA from an organism (2)ADD Restriction enzymes (3) A reproducible set of fragments (4)Inset into replicating DNA molecules (5) This gives Recombinant DNA (6) Introduce this DNA in appropriate cells Why clone a gene? Let's say you have a Genome with GeneA, GeneB & GeneC Your gene of interest is GeneA, You would (1) Select the gene of interest (2) Clone the gene, which could be used for a) DNA sequence, Protein product expression b) Gene Therapy c) Prepare the gene product in large scale Restriction digestion generates a reproducible set of DNA fragments(?) Restriction Enzymes: 1) Bacterial Enzymes that recognize a specific 4-8 base pair sequences in double stranded DNA (2) Cleave both DNA strands at the restriction sites...	2 / 448
RNA Messenger, ribosomal, and transfer RNA are the main kinds of RNA in living cells. The cytoplasm contains a further class of RNA, called small cytoplasmic RNA (scRNA), which mainly exists in the form of RNA-protein complexes...	4 / 844
Genetic Engineering Bioengineering, or genetic engineering is an altering of genes in a particular species for a particular outcome. It involves taking genes from their normal location in one organism and either transferring them elsewhere or putting them back into the original organism in different combinations...	2 / 403
