We can confirm that the diameter of the double helix structure of DNA stays the same because hydrogen bonding is always between the A and T bases and the G and C bases.
<h3>What are these bases in DNA?</h3>
The AGCT bases in DNA are the nucleotides that comprise it. These nucleotides include
- Adenine
- Cytosine
- Guanine
- Thymine
By always bonding adenines with thymine and Guanine with cytosines, the DNA strand maintains a constant diameter.
Therefore, we can confirm that the diameter of the double helix structure of DNA stays the same because hydrogen bonding is always between the A and T bases and the G and C bases.

1.is reduced
2. is oxidized
Answer:
1 mole.
Explanation:
1.6x10^23 = NA = 1 mole of any substance.
The unknown material : gold
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
mass of unknown the material : 15.06 g
volume = 0.78 ml
The density :
materials that match the density: gold
