GENES The gene is a nucleic acid sequence that is necessary for function of gene product. Gene may be a protein coding gene whose transcribed RNA is translated into proteins or RNA only genes. Protein coding genes may be solitary or families or tandem repeats NON –CODING SEQUENCE The non coding sequence are genes that do not encode the protein. The amount of non-coding sequence in DNA of organism varies among species. Eg-Human genome -98% non-coding genes Prokaryotes -10% non-coding genes Types of Non coding sequences The non coding sequences can be in the form of following Introns Anti leader and Anti trailer sequence Promoter sequence Enhancers Pseudogenes Gene fragments Telomeres Non-coding functional RNA Cis-Trans regulatory elements INTRONS Introns are non-coding sequence that transcribed into RNA But precursor mRNA removed by splicing during processing. The eukaryotic genome has large amount of introns...
BIO MOLECULES What are bio molecules is a first thing that every biochemist and biochemistry intrested persons should know . So,bio molecules are basics for biochemistry.So,today we are going to discuss about biomolecules. CARBOHYDRATES It is a basic component in biological system Here I am showing a very basic classification on carbohydrates I'll discuss it briefly in future posts AMINO ACIDS Amino acids are the compounds containing -COOH group and -NH2 group These are building block of proteins Animals and plants contains 20 different aminoacids 20 amino acids too divided to 1.essen...
