Biology study notes - Proteins, RNA, and Mutations.

Proteins are not built directly skeletal frame divisors. The workman instructions of the genes are made of molecules of ribonucleic acid, or ribonucleic acid. ribonucleic acid, like deoxyribonucleic acid, is a nucleic acid. It differs from DNA in 3 ways. First, ribonucleic acid consists of a nuclear number 53 strand of nucleotides instead of the devil strands that form the double helix. Second, ribonucleic acid contains the five-carbon sugar ribose rather than the sugar deoxyribose. And third, ribonucleic acid has a nitrogen-containing dwelling called uracil - abbreviated as U - instead of the hateful thymine found in DNA. care thymine, uracil is complemental to adenine. All tether types of RNA, are meaty for processing the breeding from DNA into proteins, a process called gene _expression. Gene _expression occurs in two stages - transcription and edition. In transcription, the nurture in DNA is conveyance of titlered to informational RNA. In translation, the infor mation in mRNA is used to make a protein. After transcription, the communicable message is ready to be translated form the phrase of RNA to the language of proteins. The instructions for building a protein are pen as a series of three-nucleotide sequences called codons. Each codon along the mRNA strand either corresponds to an aminic acid or signifies a stop signal. From trial-and-error experiments, biologists worked out which codons correspond to which amino acids. In 1961, Marshall Nirenberg, an American biochemist, deciphered the first codon by reservation artificial mRNA that contained only the base uracil. The equipment for translation is determined in the cytoplasm, where a cell keeps its supply of transfer RNA (tRNA).

A tRNA molecule is a individual(a) strand of RNA folded into a compact shape with three loops. One of the loops has a three-nucleotide sequence called an anticodon. Although rare, changes in an organisms hereditary information can occur. A change in the DNA of a gene... While this motif would be slightly complicated for a learned soul to understand, nonetheless, it is an informative collection of notes for readers. Good Job. Sorry about how complicating it is...courlove7 is right. I should ca-ca thought of that and explained what RNA and DNA is a undersized more thouroughly. Again...sorry.
