Answer #1

tRNA is known as Transfer ribonucleic acid. It is a loopy, twisted molecule. It has three distinct loops and is attached to a specific amino acid.

Protein synthesis is also known as translation. In translation, the cell uses the genetic information from mRNA for synthesis of proteins. During the process of protein synthesis, mRNA anticodons bind to the codon of the mRNA. The role of tRNA is to recognize a specific codon and to deliver the corresponding amino acid. Each codon is recognized by a tRNA, which binds to the amino acid.

Interaction of tRNA with mRNA and ribosomes:

tRNAs interacts with mRNA in translation phase i.e translation of mRNA sequence to a chain of amino acids. tRNA binds to the A and P sites of ribosomes.

Describe the synthesis of DNA polymerase starting with the synthesis of the mRNA (transcription has already happened). Stop here and think about the protein DNA polymerase – what does it do? where does it function? (you should know this from general biology – if not, look it up!) Explain the details of how this protein is made and targeted to its final destination. Since you are starting with mRNA, be sure to discuss how the mRNA gets to the ribosome....

Protein synthesis requires energy in the form of ATP and GTP. Two high-energy phosphate bonds (from ATP) fuel the formation of one aminoacyl tRNA. Formation of the initiation complex requires energy from one GTP. Delivery of each new tRNA to the Asite requires one GTP. Termination requires the hydrolysis of one GTP.   Based on this information, the table of codons, and your understanding of the processes of Activation, Initiation, Elongation, and Termination, answer the following questions. How many high energy...

The antibiotic erythromycin disrupts protein synthesis by preventing ribosomal translocation.  It does not affect any other step in protein synthesis.  Suppose you are doing a translation reaction in vitro and you add erythromycin just before the 3rd bond is about to be made.  You wait a few minutes and look at the ribosome. The carboxyl end of the amino acid #3 should now be covalently bonded directly to ___________________ Which tRNA will you find in the A site? ___________________________ The tRNA in the...
