Document Summary

Central dodgma of biology is the way genetic information is stored and retrieve in living cells. Dna acts as like a storage molecule which reads out the info into an rna molecule. Rna"s carry info which is used to produce proteins. Protein is the action molecule in the cell, ex. catalyzes reactions, creates structures, moves things around, etc. Dna is the genotype (sum of inheritable potential) and protein is a phenotype (sum of observable characteristics). Dna (genotype) rna protein (phenotype) (action molecule) Human genome project led to development of fast&accurate dna sequence determination techniques. Human genome consists of 3. 2 billion base pairs & 25000 genes in total. But the function of most genes is unknown. Protein is made up of amino acids (building blocks), which are strung together in polymer chains. Amino acids polymer chains protein. Proteins fold into 3d shapes to create a structure that functions.
