What process thought to have changed the genetic code over billion years ago?

Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.


What process is thought to have the genetic code after billions of years?

The process thought to have established the genetic code after billions of years is known as molecular evolution, particularly through the mechanisms of natural selection and genetic drift. Initially, simple RNA molecules are believed to have formed spontaneously and acted as both genetic material and catalysts, leading to the development of more complex forms of life. Over time, the transition from RNA to DNA as the primary genetic material allowed for greater stability and information storage, culminating in the genetic code we recognize today. This evolutionary journey reflects the gradual accumulation of mutations and adaptations that favored more efficient and effective means of heredity and protein synthesis.


How could human thought travel 24 billion miles per second?

Human thought does not travel at a physical speed like light or sound. It is a neurological process that occurs within the brain at a much slower pace. Communication can travel at the speed of light through technologies like fiber optics, but human thought is a complex internal process that does not have a measurable speed in terms of distance covered per second.


What was the other type of molecule that some scientists thought might carry genetic information?

protiens


When did mitosis originate?

1.5 to 2 billion years ago. when the eukaryote cell is originated, so did mitosis. So you would see at the 23rd minute of the video below.
