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…
Scientists at the National University of Singapore (NUS) have developed a unique low-cost way of cancer testing. This novel test, known as the Heatrich-BS assay, sequences clinical samples that have been heated in order to identify cancer-specific signals contained in…
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…
Reverse transcriptase is an enzyme that copies single stranded DNA into double stranded DNA. Reverse Transcriptase Enzyme It is an RNA-dependent DNA polymerase that is used in the viral replication because they can only replicate their DNA when they are…
Nucleases, also called nucleodepolymerase or polynucleotidase are enzymes able to cut off the phosphodiester bonds that join the adjacent nucleotides in a nucleic acid like RNA and DNA. Nucleases are highly essential cellular machinery that is naturally present in biological…
Ribozyme (ribonucleic acid enzyme) is an RNA molecule that has catalytic properties and is able to perform specific biochemical reactions, similar to the action of protein enzymes. Ribozymes have the following characteristics: They use RNA as a substrate. Ribozymes have…
