Biology question... pls help!!?
do your own homework.
Reply:1. E


2. B


3. sugar, base, and phosphate. that means C:3
Reply:1) E. - once the proetin has been assembled during translation it will often combine wit other ones to form tertiary and querturnary proteins





2) B. mRNA - messenger RNA - it takes the gene from nucleus to a ribosome where it can be read.





3) C. 3 subunits (1 phosphate 1 sugar 1 base)
Reply:1. b
