WebMany scientists who subscribe to this hypothesis think that RNA, not DNA, was likely the first genetic material. This is known as the RNA world hypothesis. Scientists favor RNA over DNA as the first genetic molecule for several reasons. Perhaps the most important is that RNA can, in addition to carrying information, act as a catalyst.

WebMar 22, 2024 · DNA replicates by separating into two single strands, each of which serves as a template for a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix. Two new double-stranded molecules of DNA are produced, each containing one of the original strands and one new …
WebScientists use the phrase “descent with modification” because even though related organisms have many of the same characteristics and genetic codes, changes occur. This pattern repeats as one goes through the phylogenetic tree of life: A change in an organism’s genetic makeup leads to a new trait which becomes prevalent in the group.
