If a cells nucleus has 55% adenine bases, how many cytosine bases will be present?

Nostrana [21]3 years ago

If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as  guanine bases.

This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).

DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.

irga5000 [103]

Answer:

The correct option is C. A virus contains RNA or DNA in a protein coat.

Explanation:

Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.

The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.

The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.

A gardener is installing several large flower beds. The flower beds will vary in length from 5 to 12 feet. Depending on the type
dezoksy [38]

The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.

<h3>How to calculate amount of landscaping plants?</h3>

 just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.

<h3>How to calculate the spacing between plants?</h3>

If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).

With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
