Summary Introduction

Introduction: Nucleotides are ubiquitous molecules and building blocks of the nucleic acids. There are two types of nitrogenous bases: purines and pyrimidines. Adenine and guanine are the purine bases with double ring structures. Cytosine and thymine are the pyrimidines bases that have single ring structure.

what is the first event to take place in translation in eukaryotic cell? a. An clongation of the polypeptide chain by the addition of amino acids b. Binding of the larger ribosomal subunits to the smaller ribosomal subunits c. Base pairing of activated methionine-tRNA to AUG of messenger RNA d. The small subunits of ribosome recognizing and attaching to 5' cap of mRNA
how does eukaryotic ribosome find the mRNA to be translated?  A. the sigma factor B. the shine-Dalgarno sequence C. the Inr sequence D. the 5'cap
How is translation different in prokaryotes and eukaryotes? a. In prokaryotes, because they do not have a nucleus, the translation of mRNA occurs while it is being transcribed b. In prokaryotes, pre-mRNA translation before transcription occurs within the cell c.In prokaryotes, reverse trancriptase simultaneously translates and transcribes mRNAd.In prokaryotes, functional mRNA allows for translation to be skipped, and proteins are made during transcription
