TYPES OF NON CODING SEQUENCES

  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

                                         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.essential and 2.non esssential amino acids


LIPIDS

   Lipids are  fatty and greasy materials

These are esters of glycerol and fatty acids


Classification of lipids commonly takes place as follow


so these are basic information about bio molecules.We shall know it briefly in future posts

DNA As Genetic material- Key experiments

DNA As Genetic material 1. GRIFFTH EXPERIMENT It is also called as as transformation principle . It involve in bacterial transformation.  Frederick giffth proposed this experiment. The pneumonia bacteria which causes pneumonia is used for this experiment Strains of bacteria:  1.Rough strain  It has rough appearance  It is avirulent and non pathogenic  It does not have capsule  2.Smooth strain  It has smooth glistering appearance  It has capsule made of polysaccharide  It is virulent pathogenic Strains  S types- SI, SII and SIII  R types-RI,RII and RIII  Both S and R types differ in each other antigen  Smooth forms may be mutated to rough forms but the changes are not reversible Procedure  Step 1  The laboratory mice inject With live RII pneumonia  The mice suffered no illness  Because RII pneumonia is avirulent  Step 2  But when mice inject with Virulent SIII pneumonia  The mice suffere...

ORGANISATION OF GENOME

ORGANISATION OF GENOME  Chromatin is compact organisation of DNA sequences are structurally inaccessible and functionally inactive.  Within a cell the DNA is associated with proteins is called chromosomes.  The organisation found in both prokaryotic and eukaryotic cell.  The organisation of DNA is essential to fit a DNA of 2metre length (atypical human cell)into a nucleus that is only 10-15µm in diameter. ADVANTAGES OF ORGANISATION: Packaging of DNA into chromosomes hold several functions  First chromosome is a compact form of DNA that readily fits inside cell.  Second packaging DNA into chromosome serve to protect the DNA from damage. Naked DNA molecules are relatively unstable in cells. In contrast chromosomal DNA is extremely stable. Third only packed DNA can be transmitted efficiently to both daughter cells during cell division. Fourth chromosomes confers an overall organisation of DNA , that helps in gene expression and recombination. PROTEINS INVOLVED...
