Chromosomes are thin strands of DNA (deoxyribonucleic acid). A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are different ...

Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell. Large compressed DNA molecules with associated proteins, called chromatin, are mostly present inside the nucleus. Some cytoplas...
DNA was isolated and discovered chemically before its functions became clear. DNA and its related molecule, ribonucleic acid (RNA), were initially identified simply as acidic molecules that were present in the nucleus. When Mendel’s experiments on genetics were rediscovered, it became clear that heredity was probably transmitted through discrete pa...
When its definitive role in heredity was established, understanding DNA’s structure became important. Previous work on protein crystals guided the interpretation of crystallization and X-Ray differaction of DNA. The correct interpretation of diffraction data started a new era in understanding and manipulating genetic material. While initially, scie...
As microscopes started to become more sophisticated and provide greater magnification, the role of the nucleus in cell division became fairly clear. On the other hand, there was the common understanding of heredity as the ‘mixing’ of maternal and paternal characteristics, since the fusion of two nuclei during fertilization had been observed. Howeve...

Jan 22, 2021 · Definition. Homozygous is a term in the field of genetics that describes two identical copies of alleles in the DNA gene sequence that encodes for a particular trait. As we obtain our genetic material from a father and a mother, not all of the double-strands of our DNA is exactly the same. Homozygosity can occur throughout the DNA in any ...
In simple terms, biology is the study of life. This is a very broad definition because the scope of biology is vast. Biologists may study anything from the microscopic or submicroscopic view of a cell to ecosystems and the whole living planet (Figure 1.2).
