Deep dive into the structure and functions of DNA & RNA. This PPT covers their molecular composition, roles in biology, and key differences in detail

At the core of life’s complexity lies DNA and RNA—molecules that carry the instructions for growth, development, and cellular function. DNA, with its double-helix structure, serves as the long-term storage of genetic information, while RNA, its single-stranded counterpart, plays multiple roles in gene expression and protein synthesis. Understanding their interplay is crucial in fields like genomics, biotechnology, and medicine. In this episode, we unravel their secrets, from replication to transcription and translation, providing a comprehensive look at life’s molecular foundation,

Understanding DNA structure and organization is crucial in molecular biology and medicine. This guide covers key concepts like nucleosome assembly, euchromatin vs. heterochromatin, histone modifications, and DNA packaging, with exam-style case-based questions to enhance learning.

Prepare for higher-order case-based questions by mastering the basics! This post covers 50 key questions on the structure and functions of DNA & RNA, DNA packaging, and chromosome structure

Oncogenes are key drivers of cancer, originating from proto-oncogenes that regulate normal cell functions. When mutated or overexpressed, they lead to uncontrolled cell growth and tumor formation. This article explores the molecular mechanisms of oncogene activation, including point mutations, gene amplification, chromosomal rearrangements, and viral insertional mutagenesis. Understanding these pathways has paved the way for targeted cancer treatments, offering new hope in oncology research and patient care.

Tumor markers are essential tools in cancer screening, diagnosis, and treatment monitoring. This guide covers the classification of tumor markers, their role in oncology, and easy mnemonics for memorization. Discover how biomarkers like CEA, AFP, CA-125, and PSA help detect and track various cancers. A must-read for medical professionals and students!"
