Answer:

an A- A pair is wider than a CC pair.

Explanation:

One of the great scientists that worked on how the structure of Deoxyribonucleic acid is is the chemist called Rosalind Franklin. The Deoxyribonucleic acid can be divide into three main, namely: the nitrogen base[ that is the adenine, guanine, cytosine and the thymine], the phosphate and the deoxyribose.

From Franklin's work, it was shown that the Deoxyribonucleic acid is a structure composing of double helix with both having the adenine, guanine, cytosine and the thymine. The diameter will not be the same because there is the case of Adenine- Adenine being wider than Cytosine- Cytosine.

Which of the following best describes how cleaning products like chlorine, hydrogen peroxide, and soap influence the infectious
torisob [31]

Answer:

These cleaning products break apart the capsules of the viruses causing them to no longer be capable of infecting an individual.

Explanation:

Bleach oxidises organic molecules. This causes proteins to become denatured, or lose their shape. The viral capsule containing the DNA is a coat made up of proteins that is required for the virus to become infectious. Therefore, following bleach treatment, the viral protein capsule become oxidised, cause them to loses their shape, meaning the virus can no longer infect individuals.

Anna35 [415]

Answer:

primer

Explanation:

Most biological reactions rely on the enzyme to speed up the reaction. In the case of DNA replication, this enzyme is DNA polymerase. a; DNA is a double helix made up of two long chains of deoxyribonucleotides. ... b; a primer is used to start this process by giving DNA polymerase something to bind the new nucleotide to. just for you to see.

If i wanted to look at a onion cell what type of microscope would be best to use
poizon [28]
It is best to use regular light microscopes to observe that.

For simple structures, onion cells doesn't require a very large magnification. Magnifications for such as 100X or 150X is already enough to determine the different structures of onion cells such as cell walls or cytoplasm.

It is not very suitable to use a electron microscope especially as high school or college students, as electronic microscopes can be really expensive, usually only top universities have them. Also, it is quite complicated to control the microscope comparing to the common light microscope that we can easily find in many school laboratories. They're easy to function and they're a lot cheaper.

So, it's best advised to use a light microscope, unless if you're really into studying very detailed structures and you're experienced in doing these sorts of things, then you should use a electron microscope.
