elixir [45]

Answer:Proteins have many different functions, while DNA has limited functions.

Explanation:

Chemicals that make up the living organisms consists of more protein than DNA. This is because proteins have different functions while the function of DNA are limited. Excluding water and fat, the human body is made up almost entirely of protein. Most of the structural framework of the body such as bones, muscle, organs, skin and nails are made up of protein.

Protein are responsible to do most of the work in cells by acting as enzymes, hormones and carriers. Proteins are largely required for the structure, function, and regulation of the body's tissues and organs.

In an analysis of the nucleotide composition of DNA, which of the following proportions will be found?
katrin [286]

Answer:

With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).

Explanation:

The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:

  • <em>Adenine is complemented with Thymine A=T</em>
  • <em>Guanine is complemented with Cytosine G=C</em>

From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:

<em>     A + C = G + T</em>

An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:

<em>     A + C = G + T</em>

<em>     5 + 7 = 7 + 5</em>
