7.2.3 State that DNA replication is initiated at many points in eukaryotic chromosomes – Prokaryotic DNA polymerase can work at around 1000 bases per second which means the whole circular (loop) can replicated between 20 and 40 minutes.
The eukaryotic DNA polymerase works much slower around 50 bases per second. With as many as 80 million bases to replicate the job is achieved in about one hour by having many replication forks
anticodon – a group of three bases on a tRNA molecule that are complementary to an mRNA codon 12-3
