Life on earth began as the product of chemical reactions which occurred
Kazeer [188]

Answer: Over 4 billion years ago

Explanation: The chemical reactions between carbon and water is said to bring about life according to scientists. These reactions builds largely upon four families of chemicals (lipids, carbohydrates, amino acids, and nucleic acids).

However, the actual time of life on Earth has varying speculations from different scientists in fields of study (such as molecular biology, chemistry, oceanography, etc).

Furthermore, microfossils within hydrothermal-vent precipitates dated from 3.77 to 4.28 billion years is presumed to inhabit the oldest record of life on Earth. Hence, which is presumed to have occurred after ocean formation 4.4billion years ago.

Thus, the actual date of the chemical reactions that brought about life is not rigid, but presumed to have occurred over 4billion years ago (according to research).

Conventional genetic analyses of prions involving rrna sequences are impossible because?
Reptile [31]

Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids

The name "prions" refers to aberrant, pathogenic agents that are transmissible and capable of inducing improper folding of specific normal cellular proteins known as prion proteins, which are abundant in the brain.

Prions are virus-like creatures that contain a prion protein. These elongated fibrils (green) are thought to be protein aggregations from the infectious prion. Prions cause neurodegenerative brain illness by attacking nerve cells. Symptoms of "mad cow" include glassy eyes and uncontrollable bodily trembling.

Prion disorders develop when normal prion protein, which is found on the surface of many cells, becomes aberrant and clumps in the brain, causing harm to the brain.
