Mcqs On Protein Synthesis
Translation is the process of producing functional proteins by reading the genetic information from messenger RNAs (mRNA). Protein synthesis then takes place in the ribosomes.
Protein synthesis is an important topic to study for NEET preparation. Transcription of mRNA from DNA genes in the nucleus is the first step in the process. Previously, different types of RNA were produced using suitable DNA. The RNAs then travel from the nucleus to the cytoplasm. Practicing multiple choice questions can help you prepare for the exam.
