Answer:
RNA world hypothesis.
Explanation:
RNA is present as the genetic material in some viruses only. RNA is produced from the template DNA by the process of transcription and helps in the protein gene expression.
According to RNA world hypothesis, RNA is considered to be the first genetic material as it has the ability to store the genetic material. The oxyribose sugar makes the RNA more reactive than the DNA molecule. The RNA also has the ability to work enzyme known as ribozyme. Hence, RNA has the ability to store the information and acts as catalyst.
Thus, the answer is RNA world hypothesis.
D DNA contains the blueprints for producing the organism
Answer:
Around 4.1 billion years ago, the first single celled life form appeared on Earth
Answer:
kinetic energy
Explanation:
When the molecules or atoms of a substance have high kinetic energy, the atoms/molecules move rapidly and collide frequently and harder. Most collisions are inelastic meaning that some of the energy in the collision is lost mostly as heat. This is why increasing the kinetic energy of a substance’ atoms/molecules causes the temperatures of the substance to rise. This is how heating by magnetic induction works.
