major discoveries in biology


In bacterial synthesis of insulin, an insert containing human insulin genes is inserted into E. coli through a process referred to as transformation using a plasmid vector. The father and son team from German town Middleburg have placed two spectacle lenses into a tube, one above the other and found out that such an instrument helps see microscopic objects. This practice laid the foundation for the later work of Dr. Edward Jenner, who developed the first vaccine against smallpox, in 1796. They are basic, and without them, most of us can barely survive. Currently, scientists are able to correct genetic disorders in humans through the use of gene therapy, whereby faulty or deficient genes are replaced with functional genes (Castilho, 2008). 1. 100 Greatest Discoveries recounts the 100 most important scientific discoveries of all time and explains them with historical re-creations, archival footage and interviews with scientists. Therefore, SCNT appears to be a reliable approach to replicate genes of terminally-ill individuals by relatives for the continuity of genetic characteristics along the biological tree. They have shown that DNA is a double spiral with hydrogen bonds between complementary purine and pyrimidine bases. Theodor Schleiden, an animal specialist, and Matthias Schleiden, a botanist have come to the common conclusion: all living beings consist of units with similar shape and structure – cells. Gregor Mendel, a mid-19th century Austrian monk, used pea plants to perform the fundamental studies of heredity that serve as the basis for genetic concepts to this day. Later, it was found that other nucleotides could be methylated, too. This technique has aided the Human Genome Project, and it is used in the diagnosis of diseases, cloning, and sequencing of genes. 10. Louis Pasteur, a French microbiologist, and chemist are considered the father of modern microbiology. The formulation of the cell theory was the start of cell biology as we know it. 9. Cell Division (1879) Top Biology Discoveries: Biology is an incredibly diverse science.It studies life from the most microscopic beings such as viruses and bacteria to the megafauna of deep history. Referred to as the 'Ladder of Life', Aristotle's classification system was used up until the 19th century.
Chromosomes and their role in fertilization. It deals primarily with the study of life. Most of the most remarkable discoveries, which have contributed significantly to the development of modern biology, are based on cell biology (Simon et.al. The Krebs Cycle (1937) Moreover, this discovery has led to a significant social impact in the society because; the correction of genetic defects among individuals has prolonged the life-span of the concerned populations.

Hooke’s discoveries have started a trend in using microscopes for life studies, which have eventually led to multiple crucial discoveries. Even before such advanced technology, human beings still researched and discovered a lot of life-changing improvements.
