Yes — through Reverse Transcription! This video explains the exception to the Central Dogma and its biological importance. 📌 Topics Covered: • Central Dogma of Molecular Biology (Crick, 1958): DNA→RNA→Protein • Extended Central Dogma — exceptions: RNA→DNA (Reverse Transcription) RNA→RNA (RNA replication in RNA viruses) DNA→Protein (direct translation — rare) • Reverse Transcriptase enzyme (Howard Temin, David Baltimore, 1970) • Retroviruses (e.g. HIV): RNA genome → DNA using reverse transcriptase • cDNA (complementary DNA) synthesis • Significance in biotechnology and medicine • NEET MCQ on central dogma exceptions ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Transcript with Timestamp 0:00 Normal central dogma: DNA → mRNA → protein (Crick) 3:02 If RNA is genetic material: RNA → (reverse transcriptase) → DNA → mRNA → protein 4:15 Reverse transcription = Teminism (named after Temin and Baltimore) 4:42 Examples of RNA genetic material: TMV, HIV (always have reverse transcriptase) 5:22 Retroviruses: RNA genetic material 5:44 Process: virus attaches → injects RNA → reverse transcription → DNA formed → RNA-DNA hybrid 7:48 DNA → mRNA (transcription) → viral proteins (translation) 10:03 Many viruses assembled → host cell ruptures → viruses released ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Amazon Brand Store at https://www.amazon.in/neelabakoretuto....
