Describe the structures of proteins and nucleic acids, and then explain the relationship between these two molecules within a ce
barxatty [35]
<span>Proteins are large biological molecules consisting of one or more chains of amino acids.  Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job. 
    </span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.  
    </span><span>
 Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>

Mandarinka [93]

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin  are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.
