At which end is the first amino acid synthesized of a protein ?

Question

5'
3'
Amino End
R-group
Carboxyl End

Answer 1

amino end

Answer 2

sort of an odd question...
first amino acid placed on mRNA is on the 5' end

proteins are formed from the n-terminus to the c- terminus or amino end to carboxyl end

so I would go with amino end is synthesized first

bty r-group is a side chain

hope this helps
