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 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 Genetic Code
Genetic code refers to the set of rules that govern the translation of genetic information carried by DNA or RNA into functional proteins. It involves […]
MCQ on Cyclic AMP Structure and Functions
Cyclic AMP (cAMP) is a signaling molecule involved in intracellular communication. It is derived from adenosine triphosphate (ATP) and functions as a second messenger, activating […]
