Post-transcriptional modification refers to alterations made to mRNA molecules after transcription but before translation in eukaryotic cells. These modifications include 5′ capping, 3′ polyadenylation, and splicing, which enhance stability, regulate translation, and increase mRNA diversity, essential for proper gene expression. This is an MCQ on Post Transcriptional Modification with answer key. Molecular Biology Notes | […]

MCQ on DNA Replication in Eukaryotes
DNA replication in eukaryotes involves initiation at multiple origins, proceeding bidirectionally from replication forks. Enzymes like DNA polymerases synthesize new strands, while helicases unwind the double helix. This process ensures accurate duplication of chromosomes during cell division, vital for genetic stability and inheritance. This is an MCQ on DNA Replication in Eukaryotes. Molecular Biology Notes […]

MCQ on Translation (Protein Synthesis)
Translation is the process by which cellular machinery converts the genetic information carried by mRNA into proteins. It occurs in the ribosomes and involves decoding the nucleotide sequence of mRNA into the corresponding sequence of amino acids, crucial for protein synthesis. This is an MCQ on Translation (Protein Synthesis) in Prokaryotes and Eukaryotes. Molecular Biology […]

MCQ on Translation in Eukaryotes
In eukaryotes, translation occurs in the cytoplasm following transcription. The mRNA, after processing, binds to ribosomes, where it is decoded by transfer RNA (tRNA) molecules to assemble amino acids into a polypeptide chain. This process requires initiation, elongation, and termination factors for protein synthesis. This is an MCQ on Translation in Eukaryotes (Protein Synthesis in […]
