Question

I need some serious help but dont have the time to put each question up so I will highly rate any and every question answered below:

pg.96
1) What scientific efforts ultimately led to the discovery of the molecular structure of DNA by Watson and Crick?

3) How are the instructions for various hereditary traits encoded using only four nucleotides?

5) How can recombinant DNA techniques be used to treat genetic defects and restore normal function in a given organism?

8) What techniques are being used to map specific genes on the DNA molecule?

pg. 110
3) How are amino acids linked together to form three-dimensional polypeptide chains?

4) How does the study of bacteria cells help us understand how protein synthesis works in human cells?

7) How does slime mold help scientists understand how genetic control systems work?

9) What is the mechanism that causes cancer and what are its causes?

Explanation / Answer

Watson and Crick used data from X-Ray crystalography as well as theoretical models on 3-D configuation of nucleic acids to deduce the structure of DNA.
