What did Rosalind Franklin contribute to the understanding of DNA molecules?

• An image indicating the shape of  DNA molecule

• An analysis of the chemical makeup of a DNA molecule

• A thought that DNA carries genetic information

• A theory about how DNA conveys genetic information

The weakness of hydrogen bonds between the bases of DNA allows - 

• rearrangement of the sequence of bases to take place

• base pairs to separate during transcription and replication

• new bases to be incorporated into the DNA molecule

• conversion of bases to amino acids in the event of cell starvation 

In 1950, Erwin Chargaff discovered that the percentage of adenine in DNA equals the percentage of thymine, and that the percentage of cytosine equals the percentage of guanine. This proved invaluable to the eventual discovery of which aspect of DNA?

• Location

• Solubility

• Structure

• Volume

Medicines are being produced using recombinant DNA technology. For veterinarians, the use of this DNA technology will result in - 

• decreasing the number of antibodies produced by pets 

• altering the chromosomes of healthy pets

• making more treatments available for pets

• identifying new diseases spread by pets
