The genetic code is carried out by the Deoxyribonucleus acid DNA molecule in most organisms. Most of the viruses have RNA as their genetic material which codes genetic information.
Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.
Answer:Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past and determine absolute dates for everything from wood to food, pollen, poop, and even dead animals and humans.
Explanation:
C. F1 generation is all Yy (let Y be yellow and y be green). Y is dominant to y. The F2 could be YY, Yy, Yy, or yy. 3:1
Answer:
TRUE
Explanation:
Yes this is true that Complex DNA repair mechanisms in many organisms is a challenge to Darwinian evolution because DNA repair is complex involving many proteins and Darwinian evolution would need to evolve all of these proteins simultaneously. The importance of neutral mutations has emphasized by Evolutionary theory.
DNA repair: The process through which cell repairs it's impaired DNA is called DNA repair process.
