DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA. The remaining percentage is makes us unique. Although this might sound like a small amount, it means that there are around three million base pairs that are different between two people.these differences…
The human genome project (HGP) was an international scientific research project with goal of determining the base pairs that make up human DNA, and of identify, mapping all of the genes of the human genome from both a physical and a functional standpoint. Human Genome project Start date :- 1990 Completed :- April 2003 Methodologies…
Operon :- Operon consists of a coordinated group of genes which are transcribed togather and regulate a metabolic pathway as a unit. Example – lac operator is present only in lac operon and it interacts specifically with lac repressor only. The lac operon :- The lac operon is an operon required for the transport and…
Gene expression results in the formation of a polypeptide, it can be regulated at several levels. The genes in a cell are expressed to perform a particular function or a set of functions. Example 1. The development and differentiation of embryo into adult oranisms are a result of the coordinated regulation of expression of several…
Translation :- It refers to the process of polymerisation of amino acids to form a polypeptide or protein. The order and sequence of amino acids are defined by the sequence of bases in the mRNA.
Genetic Code :- The genetic code was accomplished by the American biochemists – M. W. Nirenberg, R. W. Holley and Hargobind khorana in the early 1960. For example-the sequence of AUG is codon that specified the amino acid methionine. Table:- the codons for the various amino acids. Abbreviations used for the amino acids:- Ala- Alanine…
