Are the earth's ocean floor and continents the same age geologically? why or why not?

No, the ocean floor is much younger because new crust forms there.

Explanation:

The Earth's ocean floor and the continents are not the same age geologically. The ocean floor is much younger because new crust forms there. New crust is usually formed at the oceanic spreading centers. This process takes place when the oceanic plates pull apart, and molten lava wells up from the mantle to fill the openings. This effectively functions as a recycling system for the oceanic lithosphere.

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
