Answer:
1. The bases are on the <u>interior</u> of the double helix.
2. They are arranged<u> neatly stacked</u>.
3. The phosphate groups are on the <u>exterior</u> of the DNA molecule.
4. The sugar groups on the <u>exterior</u> of the DNA molecule.
Explanation:
DNA is made up of basic chemical components called nucleotides. These basic components include a phosphate group, a sugar group and one of four types of alternative nitrogenous bases. To form a strand of DNA, the nucleotides unite to form chains, alternating with the phosphate and sugar groups.
The four types of nitrogenous bases found in nucleotides are: adenine (A), thymine (T), guanine (G), and cytosine (C). The order, or sequence, of these bases determines which biological instructions are contained in a strand of DNA, being within the strands already mentioned.
Answer:the first one is D second one is A and the third one is A :D
Explanation:
Answer:
C : t-BuOMe
Explanation:
The tert -butanol is a tertiary alcohol and when chloride ion attacks the carbocation, it forms t-BuCl.
The reaction of tert-butyl chloride or t-BuCl ((CH3)3C−Cl) with methanol and MeOH (CH3−OH) gives the product tert-Butyl methyl ether or t-BuOMe (CH3)3C−OCH3:
(CH3)3C−Cl + CH3−OH => (CH3)3C−OCH3 + HCl
Hence, the correct asnwer is C : t-BuOMe
Total mass stays the same
B
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the final pressure by using the Boyle's law as an inversely proportional relationship in pressure to volume at constant temperature:
Thus, we solve for our target, P2, to obtain:
