Best Answer

Because DNA is a much stable molecule than RNA. However, in many viruses genetic information is encoded in their RNA. Consequently, these viruses mutate at a very high rate and change constantly to avoid onslaught from the host's immune system. If the DNA were to mutate as rapidly as RNA, the life would not be as we know it.

Proteins are made up of amino acids and amino acids and there are over 20 types of amino acids. DNA only has 4 or sometimes 5 nucleotides. Therefore, the scientists believed that since the body is so complex and that proteins can have a more advanced sequence, hereditary information was from proteins.

However, they were wrong as we now know :)

Do the human sperm and egg cell each normally carry one third of the genetic information of the potential offspring?

No - they carry half of the genetic information. The new offspring will have half their genetic information from each parent. Therefore sperm and egg cells carry half the amount of genetic material found in normal cells.
