COVID-19 is an infectious disease caused by the novel coronavirus SARS-CoV-2. It primarily spreads through respiratory droplets, leading to symptoms ranging from mild respiratory issues to severe pneumoniThe pandemic, first identified in late 2019, has had a global impact on public health and daily life. This is an MCQ on […]
Pyrimidines are nitrogenous organic compounds with a single-ring structure. They are fundamental building blocks in DNA and RNA, with cytosine, thymine (found in DNA), and uracil (found in RNA) as common examples. Pyrimidines participate in genetic coding and other cellular processes. This is an MCQ on Pyrimidine Structure and Functions. […]
Purines are nitrogenous organic compounds that consist of a double-ring structure. They are essential components of DNA and RNA and play crucial roles in cellular processes. Common purines include adenine and guanine, which are involved in genetic information storage and various metabolic functions. This is an MCQ on Purines: Structure […]
Purine and pyrimidine are two types of nitrogenous organic compounds. Purines, like adenine and guanine, have a double-ring structure and are found in DNA, RNA, and various cellular processes. Pyrimidines, including cytosine, thymine, and uracil, possess a single-ring structure and play a vital role in nucleic acids, such as DNA […]
Purine and Pyrimidine metabolism are essential biochemical pathways responsible for the synthesis and degradation of purine and pyrimidine nucleotides. Purines (like adenine and guanine) and pyrimidines (like cytosine, thymine, and uracil) are the buildin blocks of DNA and RNA. These pathways ensure the balanced production and utilization of these nucleotides, […]
