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 […]
MCQ on Chromosome Structure and Functions
Chromosomes are thread-like structures found in the nucleus of eukaryotic cells. They consist of DNA tightly coiled around histone proteins. Chromosomes carry genetic information in […]
MCQ on Histone: Organization and Functions
Histone proteins are highly alkaline proteins found in eukaryotic cell nuclei. They form the core around which DNA wraps to form nucleosomes, the basic units […]
MCQ on Rough Endoplasmic Reticulum
The rough endoplasmic reticulum (RER) is a cellular organelle characterized by its studded appearance due to ribosomes attached to its surface. It plays a vital […]
