Both transcription and translation have Initiation, Elongation, and Termination phases. LIST and BRIEFLY DESCRIBE the major features of each (4 pts each). You may use prokaryotic or eukaryotic transcription. Transcription Initiation: Transcription Elongation: Transcription Termination: Translation Initiation: Translation Elongation: Translation Termination:

The protein synthesis can be divided in three phases: initiation, elongation and termination. a. Describe the initiation phase as it takes place in bacteria. b. The initiation phase in pro- and eukaryotes begin differently, when it concern the recognition of mRNA, describe these differences. c. tRNA transport amino acids to the ribosome. Which part of the tRNA molecule form a covalent link to the amino acid? And what is the name for the general class of enzymes that catalyse the...

1. Explain prokaryotic transcription initiation from promoter recognition to transcript elongation. Include the role of the different regions of the sigma factor in formation of the open complex. Explain what strong and weak promoters mean and what determines whether a promoter is strong or weak. Also explain what abortive synthesis is, why it occurs and what has to happen for promoter escape to occur. 2. Explain how the lac operon is turned on/off. What conditions lead to repressor binding, what...

Determine whether each event occurs during initiation, elongation, or termination. Initiation Elongation Termination In prokaryotes, the shine-dalgarno sequence pairs with rRna, Translocation occurs, In Ecoli, EF-Tu delivers an aminoacyl-tRNA to the ribosome, In Ecoli, mRNA binds to the 30S ribosomal subunit, Initiator tRNA enters the P site, In Ecoli, EF-Tu hydrolyzes GTP, In Ecoli RF1 recognizes UAG and binds at the A site

Eukaryotic gene regulation: transcription initiation Initiation & the transcription initiation complex (including enhancers). Promoter; TATA box; Conserved & variable regions in promoters. Eukaryotic enhancers. Why is it important that there are multiple control elements in a single enhancer? What binds to the control elements? How is it possible for a small number of activator and transcription factor proteins to regulate a large number of genes? Transcription: Elongation & RNA polymerase. RNA polymerase vs. DNA polymerase. Termination. MyoD: What makes it...
