Why were proteins and not DNA considered to carry the genetic information?

Answer 1

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.

Answer 2

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 :)

Answer 3

Proteins were initially thought to carry genetic information because they were more diverse and abundant in cells. DNA was seen as a simpler molecule due to its repetitive nucleotide structure, leading to the belief that proteins were more likely candidates for genetic material. It wasn't until the landmark experiments by Avery, McCarty, and MacLeod in 1944 that DNA was identified as the molecule responsible for carrying genetic information.

Answer 4

Because protein made RNA and rna is also type odo nucleic acid.

Answer 5

DNA is made of proteins.

Answer 6

the push-pull theory

Answer 7

because they siad to do that

Answer 8

BEcause proteins can be quite complex! (;
