lana66690 [7]

Answer:

The northwest moving Pacific Plate has moved across the 'hot spot' that created the Hawaiian Islands for millions of years. This movement has left the northwest trending island chain

Explanation:

If the Pacific Plate keeps moving across the hot spot I believe Hawaii will keep becoming a bigger island because the Pacific plates movement caused Hawaii to form.

Why would a drug that damages capsids help treat a viral infection
zvonat [6]
The capsid is the protein shell that surrounds the core of a virus where its nucleic acid is located. The capsid is made up small sub units called capsomeres. A virus consists of a nucleic acid which may either be RNA or DNA and is found in varying quantities in the virus. It is this nucleic acid that is vital to the virus' survival that is housed in the capsid. A drug that targets the capsid and damages it will cause the nucleic acid to leak out of the virus and into the surrounding while other fluids foreign to the virus will get in rendering the virus totally impaired, and due to this the virus cannot survive but will speedily die.

Boris Magasanik collected data on the proportion of each base in RNA from different species. To compare the relative amount of e
just olya [345]

Answer:

The nucleic acid is a macromolecule present in living systems in the form of either DNA or RNA, whose molecule consists of many nucleotides which are linked with each other to form long chains. The presence of DNA or RNA in an individual promotes continuity of life. The variability and complexity of nucleic acid are dependent on its constituent molecules as, sugar, a phosphate group, and a nitrogenous base. However, two monocyclic nitrogenous bases were classified purines (adenine:A, guanine:G) and pyrimidines (thymine:T, cytosine:C, and uracil:U).

In addition, RNA is a single-stranded structure which differs from DNA in two aspects, the sugar content of RNA is ribose, and pyrimidine base uracil replaces the thymine base of DNA. A ratio between two strands of DNA can be calculated by using Chargrff's rule which states that "DNA from any cell of all organisms possess a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases'.

The purine to pyrimidine ratio in RNA with different bases is given below in the following table:

Presence of single strand in RNA does not follow chargaff's rule and alters the purine: pyrimidine ratio. The above ratio of each base in the given information is not equal, due to which the ratio of purines to pyrimidines is different. The ratio of DNA and RNA is not equal because DNA has its complementary DNA strand. However, bases in RNA might vary due to its single-strandedness property, but its ratio is dependent on the species.

Therefore, it can be concluded that the ratio of purines to pyrimidines is dependent on the species due to its genetic makeup. Hence, option (c) is correct.
