Rna

(Science: molecular biology) A nucleic acid found in all living cells. Plays a role in transferring information from dNA to the protein-forming system of the cell. (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from dna to the cytoplasm and controls certain chemical processes in the cell; ribonucleic acid is the genetic material of some viruses.A nucleic acid similar to that of dna, thought the deoxyribose acid is replaced with ribose sugar and all thymine bases are replaced with uracil. Rna is a vital component of protein synthesis as it is able to read the genetic blueprint found in dna to make.

Re: I Need help in designing RNAi :?:

Hi Yuli, By its nature, RNAi is not very specific. See this blog post for a brief discussion and some citations on the topic of RNAi specificity: http://blogs.myspace.com/index.cfm?fuseaction=blog.view&blogId=496461710 ...

Re: The end of creation?

We have not currently been able to create a living entity, arguably RNA from prebiotic soup elements. We have gotten close to it but there are still major holes such as the synthesis of some nucleotide bases. Apart from that, our planets vast amounts of life ...

Tricky translation question, can someone help please?

... to an amino acid, and when the three bases are UAA UAG or UGA the peptide stops. Next, DNA is read in the 3' to 5' direction, so the strand of RNA should read: 5' (AUGACGUAUAA)UGACCGUACAUGAGUAAUACAUAAAUCAG 3' Have i done it right so far? Because this is where i lose the plot, i'm not 100% sure ...

Re: the difference between Viruses and Bacteria.

... to invade a 'host' cell and take over its machinery in order to be able to make more virus particles. Viruses consist of genetic materials (DNA or RNA) surrounded by a protective coat of protein. They are capable of latching onto cells and getting inside them. Bacteria are organisms made up of ...

Any SOLID arguments against evolution?

4. tRNA--One of the most unexplainable things I have ever seen is tRNA--transfer RNA. As you know it brings each corresponding amino acid at the proper time and in the proper sequence. No one can explain how--it just does! ...
