Reverse Transcriptase PCR (RT-PCR) is a powerful molecular biology tool with extensive applications in research, diagnostics, and biotechnology. It is widely used for detecting and quantifying RNA viruses, studying gene expression, and analyzing RNA splicing. RT-PCR plays a critical role in diagnosing infectious diseases, such as COVID-19, HIV, and influenza. […]
Reverse Transcription Polymerase Chain Reaction (RT-PCR) is a molecular biology technique used to detect and quantify RNA. It involves reverse transcription of RNA into complementary DNA (cDNA) by reverse transcriptase, followed by amplification using PCR. RT-PCR is highly sensitive and specific, allowing the analysis of gene expression, detection of RNA […]
The HIV life cycle begins with attachment to CD4 receptors on host cells, followed by fusion of the viral envelope with the cell membrane. The viral RNA is released and reverse-transcribed into DNA by reverse transcriptase. The viral DNA is transported to the nucleus and integrated into the host genome […]
The GATE (Graduate Aptitude Test in Engineering) Ecology and Evolution exam is a critical gateway for students aspiring to further their academic journey or secure prestigious roles in research and academia. As one of the most specialized domains, this exam evaluates not only the aspirant’s foundational understanding but also their […]
Global warming is caused by the increased concentration of greenhouse gases (GHGs) like carbon dioxide, methane, and nitrous oxide, primarily due to human activities such as fossil fuel combustion, deforestation, and industrial processes. These activities trap heat in the atmosphere, leading to rising global temperatures. The consequences of global warming […]
Global warming refers to the long-term increase in Earth’s average surface temperature due to the accumulation of greenhouse gases (GHGs) such as carbon dioxide, methane, and nitrous oxide in the atmosphere. It is primarily caused by human activities, including fossil fuel burning, deforestation, and industrial emissions. Global warming leads to […]
MCQ on Environment Ecology and Biodiversity: Environment, ecology, and biodiversity are interconnected concepts essential for understanding life on Earth. The environment encompasses all external factors that influence living organisms, while ecology focuses on the relationships among organisms and their physical surroundings. Biodiversity refers to the variety of life forms, ecosystems, […]
Biodiversity MCQs with Answers PDF: Biodiversity is vital for maintaining the health and stability of ecosystems, as it provides essential services like pollination, nutrient cycling, and climate regulation. It supports human well-being by supplying resources such as food, medicine, and raw materials, while also contributing to cultural and aesthetic values. […]
Biodiversity MCQ with Answers: Biodiversity refers to the variety of life on Earth, including the diversity of species, genetic variation within species, and the variety of ecosystems. It plays a crucial role in maintaining ecological balance and providing essential ecosystem services like pollination, nutrient cycling, and climate regulation. Studying biodiversity […]
