Cytosine
Full Form of CYT
What is CYT?
Cytosine (CYT) is one of the four primary nitrogenous bases found in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is a pyrimidine base that pairs specifically with guanine (G) through three hydrogen bonds in the DNA double helix. In RNA, cytosine also pairs with guanine. This base plays a fundamental role in storing and transmitting genetic information. The presence of cytosine in nucleic acids is essential for processes such as DNA replication, transcription, and translation. In the Indian educational context, cytosine is extensively studied in Class 11 and 12 Biology, particularly under molecular biology and genetics. It is also a key topic for competitive exams like NEET, AIIMS, and various state board medical entrance tests. Students often encounter cytosine while learning about Chargaff's rules, base pairing, and the central dogma of molecular biology. Understanding cytosine helps in grasping concepts related to mutations, epigenetics, and genetic disorders. The term is widely used in academic textbooks, research papers, and laboratory settings across India. For NEET aspirants, questions frequently appear on base composition and base pairing involving cytosine.
