On living in a biological revolution we have discovered the structure of the genetic substance dna—the double helix of watson and crick—the general nature of the process by which the. Dna is a code, a means of storing biological data, in the form of genes the code was systematically cracked in the 1960s, revealing that life is breathtakingly conservative if dna is an alphabet, then the words it spells out are amino acids, the building blocks of proteins and yet only 20 amino acids are encoded by dna in all life forms. The whole process from darwin to mendel, to avery, to watson and crick was a scientific revolution that gave birth to molecular biology as a new discipline molecular biology now rests on an enormous corpus of experimental evidence and i doubt that this will ever just disappear.
Rapid advances in molecular biology have not only revolutionized the detection of disease-causing organisms – but our understanding of the genetic basis of disease earlier disease detection has led to the development of new treatment options, targeted medications, and better patient care.
Found in most cells throughout the body, dna is made up of four molecules called nucleotides, referred to by their organic bases: cytosine (c), thymine (t), adenine (a) and guanine (g) within a cell, dna is organized into structures called chromosomes humans normally have 23 pairs of chromosomes, with one in each pair inherited from each parent.
For the first time, scientists can quickly and precisely alter, delete, and rearrange the dna of nearly any living organism, including us in the past three years, the technology has transformed biology. Dna molecule watson and crick showed how deoxyribonucleic acid (dna) can store and replicate genetic information chromosomes are long strands of dna carrying molecular instructions for how to build proteins life is a physical phenomenon governed by understandable laws that make testable predictions.
Biological revolution evolution has been the central pillar of biology for the last 150 years in fact, the introduction of evolution into biology has caused a biological revolution before evolution became the thing to consider, biologists were reduced to collecting and classifying.
