<span>Mendeleev was the first scientist to arrange the known elements into a table. Mendeleev decided to arrange the known elements by atomic weight and allowed Mendeleev to predict the discovery to new elements by finding and placing gaps in the table where there was a jump in atomic weight. Moseley used the x-ray wave lengths of the elements are arranged them in a table using the experimental data. This new technique resulted in some differences in the two tables like argon and potassium switching paces. cobalt was placed before nickle and tellurium was before iodine.</span>

Why is insertion/deletion of three bases less deleterious than insertion/deletion of one or two bases.
Ede4ka [16]

Answer:

Explanation:

Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.

If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.

However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.
