Molecular Biology is an interdisciplinary field of science that studies the structure and function of molecules in living organisms. It combines the disciplines of biochemistry, genetics, and cell biology to understand how living organisms work at a molecular level. Molecular…
DNA is a molecule with two strands. Only one strand codes for proteins at every given position in the molecule. However, during DNA replication, usually both strands are utilized. DNA replication is a very complex process and involves four important…
If you ask any biologist for a definition for base pairing, you’ll get a very similar explanation. Base pairing is the association between two nucleobases on opposite ends of a DNA or RNA molecule. The two nucleobases are held together…
The Basic Structure of Nucleic Acids (DNA and RNA) are the complex informational macro-molecules present in all living cells and viruses. They carry genetic information about the cell. Nucleic Acids Structure Each nucleotide unit comprising the structure of nucleic acids consists of:…
Primary Structure of DNA The sequence of nucleotide chains is the primary structure of DNA. The genetic information is stored in these channels, and while the skeleton is the same for everyone, the variation in information is found in the…
The molecular structure of DNA is the ultimate clue to its ability to replicate, code for proteins, and undergo mutation Introduction DNA consists of a double-stranded helical structure. Both the strand are complementary to each other and bonded together by double…
Molecular homology is a fascinating concept that has a lot to offer to understand the relationship between different genes and their functions. In this blog, we will unravel the mysteries of molecular homology, from what it is to how it…
The fact that DNA is the key hereditary material is well established now. But it’s worth wondering how this crucial bio-molecule positioned itself at the center of biology. The discovery of the nucleus within a cell itself is a milestone.…
Telomerase is an enzyme that replenishes the telomeres at the ends of each chromosome. Telomeres shorten every time the cell divides, which would eventually cause the chromosome to lose vital genetic information and eventually lead to cell death. In order…
Topoisomerase Enzymes are enzymes that are part of the DNA replication process. These enzymes help breaking the bonds between two strands of DNA and unwind the double helix structure. These enzymes are also used to attach a terminal protein to…
