Q1 you'll have to look the term up but the name of the end of the chromosome reflects the fact that it's at the end (telos in Greek) and it's part of the chromosome (meros in Greek). http://en.wikipedia.org/wiki/Telomere Q2 there's a clear explanation here: http://en.wikipedia.org/wiki/Griffith%27s_experiment Q3 details here: this is a particular type of virus that infects bacteria and uses them to replicate, causing them to burst. The name reflects that they are "bacteria eaters" Q4 the proof-reading activity is in the asme molecule that makes the DNA strands in replication: http://en.wikipedia.org/wiki/DNA_polymerase
