What is the role of hydrogen bonds in the structure of DNA?
to connect the base pairs
natural selection
sodium ions
a decrease in the amount of carbon dioxide in the air
It restores the diploid number of chromosomes.
a change in the sequence of base pairs
DNA --> RNA--> Protein
The population can increase in number more rapidly.
