Ribosomal RNA

admin - May 22nd, 2008 | Add comments

Ribosomal RNA (rRNA) is the central component of the ribosome, the protein manufacturing machinery of all living cells. The function of the rRNA is to provide a mechanism for decoding mRNA into amino acids and to interact with the tRNAs during translation by providing peptidyl transferase activity

Non-coding RNA

admin - May 22nd, 2008 | Add comments

A non-coding RNA (ncRNA) is any RNA molecule that is not translated into a protein. A previously used synonym, particularly with bacteria, was small RNA (sRNA). However, some ncRNAs are very large (e.g. Xist). Less-frequently used synonyms are non-messenger RNA (nmRNA), small non-messenger RNA (snmRNA), or functional RNA (fRNA). The DNA sequence from which a […]

Techniques for DNA Testing

admin - May 21st, 2008 | Add comments

DNA typing is performed by demonstrating differences in length of specific DNA sequences. This can be done by digestion of DNA with restriction enzyme(s), followed by Southern blot hybridization using a probe specific for the polymorphic site. Polymerase chain reaction (PCR) techniques are becoming widely applied to the same task, and have several advantages over […]

DNA-binding proteins

admin - May 8th, 2008 | Comments (2)

Structural proteins that bind DNA are well-understood examples of non-specific DNA-protein interactions. Within chromosomes, DNA is held in complexes with structural proteins. These proteins organize the DNA into a compact structure called chromatin. In eukaryotes this structure involves DNA binding to a complex of small basic proteins called histones, while in prokaryotes multiple types of […]
