<span>Attached to each sugar ring is a </span>nucleotide base<span>, one of the four bases </span>Adenine<span> (A), </span>Guanine<span> (G), </span>Cytosine<span> (C), and </span>Thymine<span> (T). The first two (A, G) are examples of a </span>purine<span> which contains a six atom ring and five atom ring sharing two atoms. The second two (C, T) are examples of a </span>pyrimidine<span> which is composed of a single six atom ring. A </span>base pair<span> is one of the pairs A-T or C-G. Notice that each base pair consists of a purine and a pyrimidine. The nucleotides in a base pair are </span>complementary<span> which means their shape allows them to bond together with </span>hydrogen bonds<span>. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together. Hydrogen bonds are not chemical bonds. They can be easily disrupted. This permits the DNA strands to separate for </span>transcription<span> (copying DNA to RNA) and </span>replication<span> (copying DNA to DNA). In our simple model, the entire base pair structure is represented by the single blue rod. Various more elaborate models can be constructed to represent base pairs, including the one above which shows individual atoms and bonds.</span>
Answer:
According to the picture, during a solar eclipse the moon must be in position A, interposed between the sun and the earth.
Explanation:
A solar eclipse is due to the interposition of the moon between the sun and the earth, which produces that the solar rays do not reach certain points of the planet.
The lunar phase that is shown during a solar eclipse is the new moon phase, because the satellite does not show the side illuminated by the sun. At this point, the moon must be close to the solar orbital plane for the phenomenon to occur.
Answer:
a) The simple interest is $126.
b) The total money repaid after 3 years is $1526.
Step-by-step explanation:
A man borrowed money at a bank $1400 at the rate o 3% for 3 years.
a) Find the simple interest
- → S.I = Simple Interest
- → P = Principal
- → R = Rate
- → T = Time
Substituting all the given values in the formula to find the Simple Interest :
Hence, the simple interest is $126.
━━━━━━━━━━━━━━━━
b) Find the total money repaid after 3 years
- → A = Amount
- → P = Principal
- → S.I = Simple Interest
Substituting all the given values in the formula to find the Amount :
Hence, the total money repaid after 3 years is $1526.
