During protein synthesis, the tRNA aminoacyl synthetase acts to:    covalently bind an amino acid to the acceptor stem of the tRNA

  You purify a wild-type protein from a strain of E. coli bacteria, and then sequence the first few amino acids of the protein. You find that the first few amino acids are:                 Met – Trp – Cys – His – …… Using the genetic code table given above, what is the RNA nucleotide sequence encoding these five amino acids? If the sequence is ambiguous, use parentheses. For example, if a particular base could be either an A or a G, indicate it as (AG) in your sequence. Put single space between codons and no spaces between letters in the same codon, for example GGG AA(AU) CCC Start writing from the 5′ end of the RNA sequence. 

The function(s) of topoisomerases during replication is to:    decrease tension to relieve supercoiling

Reverse transcriptase is essential for:

During protein synthesis, the tRNA aminoacyl synthetase acts to:    cause precursor tRNA molecules to adopt their proper final structure

RNA contains uracil instead of cytosine
