ANSWER:
Most types of cancer are believed to begin with a random genetic mutation. This is followed by mutations, which endow the cancer cells with properties allowing them to grow without normal controls to become a tumor.
Mutation is any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.
Genetic Mutations that lead to cancer cell formation can occur in two forms:
1. GROWTH-PROMOTING GENES are commonly mutated in cancer cells, becoming SUPER-ACTIVE and producing cells that are too strongly stimulated by growth receptors.
2. Mutations can INACTIVATE the genes that suppress cell proliferation or those that signal the need for apoptosis. These genes are known as TUMOR SUPPRESSOR GENES.

The specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.
<h3>What is Sanger sequencing?</h3>
Sanger sequencing is a technique used in molecular biology and genetics to determine the linear order of nucleotide bases in a given genomic sequence, which is fundamental to identifying alleles in a genome.
This technique (Sanger sequencing) is based on the use of certain analogous nucleotides that stop the process of amplification, which can be subsequently evidenced in an electrophoresis gel.
In conclusion, the specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.

Explanation:
1)= always starts with the letter C02= carbondioxide....
The correct answer is option A- The shape and folded structure of a protein molecule are important in determining its function.
Justification: Let's take an example of sickle cell anemia in which the structure of hemoglobin changes due to a change in one amino acid. A small change in amino acid will change the bonds which will affect the structure and folding of the protein. A single change of amino acid can results in the change of protein’s function and structure.
