Há 2 dias · Genetics is the study of genes, genetic variation, and heredity in organisms. It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.
Há 2 dias · The DNA's base pairs encode genes, which provide functions. A human DNA can have up to 500 million base pairs with thousands of genes. In biology, the word gene ( Greek: γένος, génos; [1] generation, [2] or birth, [1] or gender) has two meanings. The Mendelian gene is a basic unit of heredity.
Há 2 dias · Deoxyribonucleic acid ( / diːˈɒksɪˌraɪboʊnjuːˌkliːɪk, - ˌkleɪ -/ ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.

15 de mai. de 2024 · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
Há 3 dias · In his famous Fly Room at Columbia University, Morgan and his team demonstrated that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics.
