nnWhy it’s correct: Because once the frame is shifted, the mRNA sequence would code for the amino acids Why I got it wrong? I skipped the question and was planning to come back to it but ran out of time so I couldn’t answer it
My answer: The addition of a string of adenine nucleotides to the 3’ end of the RNA molecule Correct answer: The addition of methyl groups to certain nucleotides of the RNA molecule Why it’s correct: Because all of the others happen during RNA processing. Why I got it wrong? I got confused and mixed both of the answers up
My answer: To amplify genes
Correct answer: To separate proteins in a mixture
Why it’s correct: Because in a gel electrophoresis technique is mainly used to separate and stratify molecules, so separating proteins o a mixture would be an additional use of it. Why I got it wrong? I got confused between the answers and didn’t know what to choose, so I guessed.
