Answer:
DNA is the genetic material of all the living organism except some viruses. The structure and the characteristics of the DNA was well explained by Watson and Crick.
DNA is a double stranded molecule in which nitrogenous bases are linked together. Watson and crick explained that DNA strand are antiparallel. The antiparallel nature of the strand means one DNA gas a polarity of 5' to 3' direction whereas the another strand of the DNA gas polarity of 3' to 5' direction. These two strands has opposite polarity and runs in anti parallel directions. Thus, the DNA strand known as antiparallel strands.
Answer
<em>C. The Moon orbits the Earth about once a month</em>
Over billions of years the earth’s gravitational field has tidally locked the moon in orbit so that its rotation about its axis is the same as that of its orbit around the earth.
This process is still continuing as the earth transfers some of its angular momentum to the moon lifting it to a higher orbit by a couple of centimeters a year. As it rises, its takes a fraction longer to complete an orbit, and its rotational speed slows down slightly to match.
The eventual conclusion of this is that the earth also would become tidally locked to the moon, and they will both face each other permanently. But this is going to take that long that the sun will probably have destroyed both the earth and the moon in its red giant phase before this happens.
