2w + 2l = 63
2w + 2(1) = 63
2w + 2 = 63
2w + 2 (-2) = 63 (-2)
2w = 61
2w/2 = 61/2
w = 30.5
This is if it is a parallelogram & the like
hope this helps
Answer:
According to Chargaff's rule, if a DNA molecule has 26 cytosine base molecules it will also have 26 guanine molecules.
Explanation:
DNA is formed by the bases adenine guanine, thymine and cytosine, distributed in its two strands whose proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
<u>Chargaff found that in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there should be the same amount of thymine as adenine and a similar amount of guanine for cytosine</u>, according to the complementarity of the bases.
According to Chargaff, if a DNA molecule contains 26 cytosine bases —one pyrimidine— then it also contains 26 guanine molecules, one purine.
In the case that the molecule has a total of 100 nitrogenous bases, the amount of the other bases can also be known:
- <em>Cytosine 26
</em>
- <em>Guanine 26
</em>
- <em>Adenine 24
</em>
- <em><u>Thymine 24
</u></em>
- <em>Total 100</em>
