Plz me with these question
1)what does dna look like? why was it hard to work with?

2)who were the two people working on the crystallography of dna?

3)explain two scientists' first dna model?

4)what was another researchers reaction? and consequences?

5)whats going to happen if you are afraid to make mistakes? do you think this applies to all aspects of life? explain why.

1. DNA looks like two long and thin strands twisted aroung each other. DNA is hard to work with because it is very small and hard to see with the naked eye.

          2. James Watson and Francis Crick was the ones who found out that DNA was made up of two chains of nucleotide pairs. Ad Rosalind Franklin created a technique call x-ray crystallography.

        3. Waston and Crick first DNA model was their two strand or double helix model.

       4. im not really sure.. sorry

      5. If you are afraid to make mistakes, it will be hard for you to achieve your goal. This does apply to all aspects of life.
