Asexual Propagation in Plants PPT: Asexual propagation in plants allows them to reproduce without seeds, using specialized structures like offsets, runners, suckers, and bulbils. Offsets are small daughter plants that grow from the base of the parent plant, commonly seen in succulents like aloe. Runners (or stolons) are horizontal stems […]
Chargaff’s Rule states that in a double-stranded DNA molecule, the amount of adenine (A) always equals the amount of thymine (T), and the amount of cytosine (C) always equals the amount of guanine (G). This principle of base pairing ensures the structural integrity and replication fidelity of DNA across all […]
Chargaff Rule Questions: Chargaff’s rule, proposed by Erwin Chargaff in the 1950s, is a fundamental principle in molecular biology that describes the base composition of DNA. The rule has two main components: Base Pairing Equality: In a double-stranded DNA molecule, the amount of adenine (A) is equal to the amount […]
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 […]
