The best answer is D.
Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.
In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached mRNA is decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.

Answer;
- radiometric dating of rocks
- fossil evidence
- gradual processes of rock
Explanation;
Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place.
-The ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.
Well, Carbon has 4 Valence Electrons. I'm sure you know this, but valance electrons allow electrons to covalently bond with one another. The elements, when sharing the electrons, want to have 8 valance electrons. So carbon has 4 valance electrons so it can bond with itself, or another say 4 hydrogen [becuase hydrogen can live with 2 valance electrons]. Hope this helps. Remember: Electrons <3 8 valance electron bonds Carbon's 4 + Carbon's 4= 8 true love at first bond! OR Carbon's 4+ Hydrogen's 1 [x4] = 8 hope this help
