1. In the 1950s when Watson and Crick were working on their model of DNA, many scientists did not think that DNA carried the genetic code. What was the other type of molecule that some scientists thought might carry genetic information? *

Proteins

Explanation:

Since proteins were made up of 20 different types of amino acids and DNA was only four A,G,C and T many scientists thought that these were most likely to be carrying information. In addition to amino acids being in so many varieties they were also of different charges and shapes as well.
