ENZYMES USED IN MOLECULAR BIOLOGY TECHNIQUES

Restriction endonucleases are DNA cutting enzymes specifically found and isolated from bacteria; and which nick specific sites on a nucleotide sequence known as restriction sites. Restriction sites are the different sites on a DNA molecule that is nicked by a particular restriction enzyme. Several types of restriction enzymes exist, and they are primarily sourced from […]

CENTRAL DOGMA (FRAMEWORK) OF MOLECULAR BIOLOGY

The central framework of molecular biology otherwise known as the “central dogma” is the starting point for the actual course of movement of genetic information within the cell’s nucleus of an organism. The transfer of genetic information within the cell of an organism (i.e. in the nucleus) from deoxyribonucleic acid (DNA) to ribonucleic acid (RNA)

Overview of Molecular Biology

Molecular biology is the study of the genetic makeup of organisms at the level of deoxyribonucleic acid (DNA). It encompasses the study of the ways in which diseases and traits can be passed through the genes especially via from parents to their offspring’s. Genes are the hereditary unit or genetic material that is transmitted from

JAMES WATSON

Born on the 6th of April, 1928, James Watson is an American molecular biologist, geneticist, and zoologist, who is best known as a co-discoverer of the structure of deoxyribonucleic acid (DNA) in 1953. Watson co-discovered the structure of the DNA with Francis Crick (an English molecular biologist, biophysicist, and neuroscientist) in 1953. Watson and Crick

AVERY OSWALD (1877-1955)

Avery Oswald was a Canadian-born American physician and medical researcher who provided the molecular explanation for Griffith’s transformation of Streptococcus pneumoniae. Avery was one of the first molecular biologists and a pioneer in immunochemistry, but he is best known for his discovery in 1944 that DNA is the material of which genes and chromosomes are
