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 enzyme-mediated synthesis of new strands, ensuring genetic continuity and transmission of genetic information to daughter cells. This is an MCQ on DNA Replication in Prokaryotes […]
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 […]
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 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 […]
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 […]
