Identify the best translation start site in the mRNA below:
5’ AUGGCUUAUGCUCGTCCGCCAUGGCUUUAAGUACGGUAAAUGCUACA 3’
Usually the start site in mRNA (messenger RNA) is the first codon. The start codon always encode for methionine in Eukaryotes and Archaea except in bacteria where there is modified methionine (fMet). Most common start site is AUG.
So the first three sequence starting from 5’ AUG..... is the best translation start site in the given sequence here

Which of the following statements best describes the initiation of translation? A tRNA with the anticodon, AUG, enters the ribosomal complex and binds to the mRNA at the A site. b) The large and small ribosomal subunits scan the mRNA in the 3'-5 direction until the promoter is reached. The mRNA containing the start codon, AUG, sits at the P site and forms a complex with the corresponding tRNA, and the large and small ribosomal subunits. d) The mRNA attaches...

Place the events of Translation in bacteria into the correct order. The large ribosomal subunit associates with the small subunit and mRNA. The ribosome shifts along the mRNA in the 5' to 3' direction, moving the tRNA from the aminoacyl (A) site into the peptidyl (P) site The tRNA in the peptidyl (P) site shifts to the E site and leaves the ribosome. The next charged tRNA enters the open aminoacyl (A) site of the ribosome Aminoacyltransferase attaches the amino...
