Which binding site on a ribosome holds a tRNA attached to a growing polypeptide chain?

Which region of a tRNA molecule binds to amino acids?

In which site of the ribosome would you find an uncharged tRNA molecule during translation?

At which site do new aminoacyl tRNAs enter the ribosome during elongation?

Cells are able to distinguish proteins destined for secretion or for segregation to specific intracellular compartments from those that will remain in the cytoplasm because __________.

At which site does the charged initiator tRNA bind during the initiation of protein synthesis?

How many binding sites are present on the ribosome for tRNA during translation?

How many binding sites for tRNA are found on a ribosome?

Which of the following types of proteins is translated in the rough endoplasmic reticulum?

Controlling the rates of transcription and translation is important in bacteria to avoid collisions between ribosomes and RNA polymerases. Calculate what the maximum rate of translation by a ribosome in a bacterial cell would have to be, in units of amino acids per second, so as not to overtake an RNA polymerase that is synthesizing mRNA at a rate of 60 nucleotides per second. How long would it take for this bacterial cell to translate an mRNA containing 1800 codons?

What are the names of the three sites where tRNA molecules bind to the ribosome during translation?

In the process of translation, to which site on the ribosome does the initiator tRNA bind?

Translation results in the production of .a. RNA;b. DNA;c. protein;d. individual amino acids;e. transfer RNA molecules
