Genetic code - Principle, Features & Discovery | Biology Blog

Image
                                        Genetic Code Any biochemical process is ended up by the arbitration of the enzymes. These enzymes are consist of proteins. Every protein is cover of at least 20 amino acids, whereas the DNA is made up of only four nucleotides. The four nitrogenous bases of DNA will tell you all  20 amino acid sequences. All the genetic information for a character is coded in the nucleotide of DNA called  Codon. The sequence of nucleotide or nitrogenous bases in mRNA molecules which locked the information for protein synthesis and called as Genetic Code.   Discovery -  In 1968 Nirenberg, Khorana &Holley have discovered genetic code. Nirenberg also received a noble prize for success in genetic code.   The problem in Genetic code - The major issue of genetic code was to resolve the perfect number of nucleotides in a codon that codes for a single amino acid. Singlet Code - Since there are only four nitrogenous bases in mRNA ( A, U, G, C ) for 20

Mendelian Genetics : Biology Blog

Image
                                    Mendelian  Genetics Genetics is the branch of biology dealing in inheritance and variation of characters generation to generation.          Gregor Johann Mendel  -" The Father Of genetics "was born in 1822 in Heinzendorf, which was a part of Czechoslovakia. He was the inventor of Mendel's law,  a naturalist, a priest who began his genetic experiments on garden pea in 1856 in the garden at the monastery. Selection of pea plant:   There are some reasons for choosing garden pea (Pisum sativum) for experiments by Mendel like – Pea has many separate contrasting characters. The life span of the pea plant is very short. Flowers show self-pollination. It is easy to artificially cross-pollinate the pea flowers, therefore, the hybrids produced were fertile. Mendel’s Experiments Gregor Johann Mendel - the father of genetics proposed some laws of inheritance.           He used garden pea as his sample.

What The Doctor Say About Cord Blood Banking

Image
                                  Cord Blood Banking   A few years back,    the doctor throws away  the cord  after the delivery of a baby from the  body  of  the mother by means of waste material but now it is known to be a useful source of  blood stem cell . Cord blood is used to treat many genetic and other  disorder of the baby as well as whole family . The delivering baby contains blood in umbilical cord and placenta .  This blood is rich in  the haematopoietic cell , the cell  can able to turn into any type of blood cell weather it would be red cell ,white cell or platelets .  These  haematopoietic cells are sorted out from the blood of the cord and able to produce blood cell throughout the life of a person . Now a days every hospital of India ask the future parents for preserving  cord blood  for further use in treating leukemia , genetic disorder ad blood cell -  related diseases of his family . Setps-

Stem Cell Banking/ Cryoviva Preservation In India

                                        Stem Cell Banking  All the organism on the earth is produced by a single cell only, the fertilized egg. Eventually,  the cell differentiates or undifferentiated to produce unicellular and multicellular organism respectively. Unicellular organism dies early because there are no possibilities to replace the dead or damaging cell and this is the plus point in a  multicellular organism that all dead, diseased and damaged cell cab be replaced medically.   Research has proved that in human,  it is possible to replace the damaged cell or diseased cell with the help of stem cell treatment. What is Stem cell -  stem cell is a single hollow cell which has an ability to differentiate further to develop in a  functional organ or tissues of the body ( pluripotent )  like muscle cells, blood cells, etc.  As soon as the time flows multiple of the disease can be treated with the help of stem cells. Type Of Stem Cell -  There are following t

What are the Important features of Sycon

Image
                                             Sycon  Sycon is following the phylum Porifera . They are generally marine in nature and also spongy.   Due to sponginess, they are always attached from the base to the substratum like rocks, glass, coral,  on Mollusc shell. Sycon is generally small just like grain and too soft. Sometimes they are found on the sump . They are also known by many names like pineapple, Q tip sponges , etc.  Feature - They are generally marine animals. They are diploblastic in nature. The body is covered by two-layer; outer layer is Pinacoderm and the inner one is Choanoderm. Sycon having syconoid type of canal system. Sponges are radially symmetrica l. Sponges follow asexual and sexual both types of reproduction. Sponges are hermaphrodite . Spicules are found on its body surface. Sycon does not have any nervous system present on its body, only some neurosensory cells are present. the small pore is present on their whole body known as O
