Reasons for seasons<br>

Sergio039 [100]

Answer:

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth's axis, we wouldn't have seasons.

Now that you have identified the components of DNA, can you describe how these components bind together to form a DNA molecule?

omeli [17]

The question is incomplete. The complete question is attached below.

Answer:

1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.

2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.

3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .

4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
