A mutation causes a sequence of DNA that has the nucleotides TTG to be changed to TCG. The resulting protein has a different sequence of amino acids. Which type of mutation is this?

A mutation in which the change of a nitrogenous base in the DNA results in a protein with a different aminoacid sequence is a missense mutation.

Explanation:

Missense-type mutation occurs when the change in a nitrogenous base in the DNA is transcribed into a codon in the mRNA that encodes a different aminoacid than the original. In this sense, a different amino acid means a change in the protein, which alters its structure and function.

The consequence of this mutation is an organic, structural or functional deficiency, which determines a special condition in the affected person.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
