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 mRNA sequence and synthesize proteins by recruiting transfer RNA (tRNA) molecules that bring specific amino acids corresponding to the mRNA codons. This is an MCQ on Translation in Prokaryotes. Molecular […]

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, including splicing and addition of a poly-A tail and a 5′ cap, before being exported to the cytoplasm for translation. This is an MCQ on Transcription in Eukaryotes (Protein Synthesis […]

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 the DNA strands as a template. This mRNA carries genetic information from DNA and serves as a template for protein synthesis. This is an MCQ on Transcription in Prokaryotes. Molecular […]

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 tissue repair. Mitosis consists of stages: prophase, metaphase, anaphase, and telophase, ensuring accurate distribution of chromosomes. This is an MCQ on Mitosis. | Cell and Molecular Biology Notes | Cell […]

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 in four daughter cells with half the chromosome number of the parent cell, enabling genetic diversity. This is an MCQ on Meiosis. | Cell and Molecular Biology Notes | Cell […]
