Read this article to learn about the reverse transcriptase: - process of making a double stranded DNA with diagrammatic representation. The initial information came from study of tobacco mosaic virus (TMV) in virology that, only RNA can act as genetic material, can infect, can produce complete virus, and finally isolation of replicas. This was followed by evidence for double stranded [...]
This article throws light upon the top seven DNA damage repair mechanisms. The top seven DNA damage repair mechanisms are: (1) Proofreading by DNA Polymerase (2) Excision Repairs (3) Spontaneous Repair by DNA Double Helix (4) Homologous and Non-homologous DNA Repair (5) SOS Repair (6) Mismatch Repair of Single-Base Mispairs and (7) Photo-reactivation UV-induced Pyrimidine Dimers. Mechanism # 1. Proofreading [...]
This article throws light upon the four causes DNA damage. The four types of factors that cause DNA damage are: (1) Hydrolysis (2) Deamination (3) Alkylation and (4) Oxidation. Cause # 1. Hydrolysis: DNA consists of long strands of sugar molecules called deoxyribose that are linked together by phosphate groups. Each sugar molecule carries one of the four natural DNA [...]
