The correct answer will be-

1. Chromosomes are made up of protein and nucleic acid.

2. Genes are located on chromosomes.

3. Chromosomes are found in the nucleus.

Explanation:

Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".

The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.  

The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.

But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.

Thus, the selected options are the correct answer.
