Does the following statement describes a function of dna, a function of rna, of both dna and rna, or a function of neither dna or rna? it stores the nucleus the information a cell needs to make its proteins with the right amount of orders in amino acids. a. dna b. rna c. both dna and rna d. neither dna nor rna

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
