Q1. The flow _______of starts with DNA, sitting quietly (we hope!) in the _________of ______ cells. A temporary ________is made whenever the cell wants to 'activate' information; this copy is made of a less secure, less stable but similar molecule,_________ . The RNA copy is often altered by additions and subtractions before being sent to the _________for _________ by ___________ . In this process, _____________bearing amino acids are evaluated for 'fit' to the currently active ________of the _____________ . Those that 'pass' accept the growing __________chain, and the ribosome progresses along the mRNA until a nonsense or 'stop' codon brings the process to a halt.

Q2. Which statements are true/false about tRNAs visiting the ribosome's A (amino acyl) site?
Each tRNA...
will not stay very long if it cannot form six or more hydrogen bonds with the exposed codon _____
will only be allowed to access the A (amino acyl) site if the tRNA is going to match _______
will only match well with the exposed codon of the mRNA if the codon is the 'correct' one ______
fits if any of the three adjacent nucleotides in the tRNA's sequence can be matched to the codon _____
I have tried this question REPEATEDLY and cannot figure out for the life of me the correct answer. Please help me figure this out!!!
