Use the data and what you have learned about evolution to explain how mutation is a random process, but natural selection is not
Marina CMI [18]

The data are not found here, but evolution means 'descendence with modification', which may occur due to natural selection and mutations.

<h3>What is evolution?</h3>

Evolution is descendence with modification, which generally is caused by a process called natural selection.

Natural selection 'selects' the most adaptive variants in the population, which occurs due to the emergence of mutations.

A mutation is any genetic change in the nucleotide sequence of the genome of an individual.

Glutamic acid and valine are two amino acids with different molecular structures. (Glutamic acid is a strongly hydrophilic molec
Aleonysh [2.5K]

Answer:

Explanation:

The switch from glutamic acid to valine in position 6 of hemoglobin (HB) forms the basis of sickle cell anemia disease pathology.

Valine is hydrophobic and it's chain is shorter than glutamic acid. The lack of the carboxylic acid and shortness of valine will result in loss of the ionic interactions formed between the glutamic acid's carboxylic group and other amino acids. A hydrophobic cavity will form in the beta sheet of HB due to the short and hydrophobic structure of valine. For these reasons, the HB molecule will be less stable and insoluble in water. The insolubility is thought to be caused by fibril formation between the valine interacting with hydrophobic pocket residues of the adjacent HB molecule.  This would in turn affect binding of oxygen to HB.
