Answer:
The correct answer will be- this base pairing allows the complementation like lock and key
Explanation:
In DNA, the nitrogenous bases on one strand pairs with the nitrogenous bases on another strand.
Experiments of Erwin Chargaff showed that purine bind pyrimidines where the adenine binds thymine and guanine bind cytosine via double and triple hydrogen bonds respectively.
This hydrogen bonding between the purines and pyrimidines provides structural stability as it is based on the complementation. This complementary base pairing allows the two strands to fit like a key and a lock.
Thus, this base pairing allows the complementation like lock and key is the correct answer.
Of energy & then releases waste product
Mesomorphic would be the right answer :-)
Distribution and abundance of organisms
Speciation of plants
Antarctic convergence
1. Whether or not height affects running speed.
2. She and her friend Melissa exercised equal amounts, but Melissa still ran faster, so Sally wanted to know why.
3. speed
4. quantitative
5. males vs female data, so gender, and how much each test subject exercises, so their athleticism
6. Gender, distance ran
7. no
8. 1 trial as a class, but independent data for each student, so I would say there were as many trials as students in the class
