Consider the following statements regarding DNA replication and choose the correct answer:
1. The very first requirement of DNA synthesis is the presence of a template or plan along which the new strand is to be constructed
2. The second requirement is of a DNA-dependent-DNA polymerase or simply DNA polymerase enzyme

4. Replication takes place bidirectionally
"Too often we try to solve human problem with non-human tools and in terms of non-human data. It is my simple thesis that a human problem requires a human solution. First we have to learn to recognise a human problem when we see one; and second, upon recognising it, we have to learn to deal with it as such and not as it were something else. A human problem to be brought to a human solution requires human data and human tools". Who said this?
