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 […]

MCQ on DNA Replication
DNA replication is the process by which a cell duplicates its DNA before cell division. It involves unwinding the double helix, complementary base pairing, and […]
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 […]
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 […]
MCQ on Translation in Prokaryotes
In prokaryotes, translation begins while transcription is ongoing. The mRNA, produced by RNA polymerase, directly binds to ribosomes in the cytoplasm. Ribosomes then read the […]
MCQ on Transcription in Eukaryotes
In eukaryotes, transcription involves RNA polymerase binding to the promoter region on DNA, followed by synthesis of a complementary mRNA strand. This pre-mRNA undergoes processing, […]
MCQ on Transcription in Prokaryotes
In prokaryotes, transcription is the process where RNA polymerase binds to the promoter region of DNA and synthesizes a complementary mRNA strand using one of […]
MCQ on Mitosis
Mitosis is a type of cell division in eukaryotic organisms, resulting in two identical daughter cells. It plays a crucial role in growth, development, and […]
MCQ on Meiosis
Meiosis is a type of cell division that produces gametes (sperm and egg cells) in sexually reproducing organisms. It involves two rounds of division, resulting […]
