Question

what is the "chicken or egg"prolem with DNA and enzymes ,10marks

Answer 1

The problem with DNA and enzymes is both are required for each other formation. So, you can't make DNA without enzymes and enzymes can't be produced without DNA. This problem is just like which came first egg or chicken. But problem with DNA and enzymes came to an conclusion after discovery of enzymatic active RNA i.e. ribozyme which suggest that during early days these polymers had self enzymatic properties as no enzyme was available then later enzyme came with time.
