Three scientists are credited with the development of cell theory. Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name.

Please help me with 1-3
Korolek [52]
Answer:
1. Substitution
2. Insertion and deletion
3. Amino acids can have more than one codon that signals for it. Due to this, some substitutions don’t affect the protein at all.

Explanation:
1. Substitution sometimes isn’t as impactful. It can result in the same amino acid to be signaled as the original one since amino acids can have more than one codon signaling for it.
2. Insertion and deletion are also known as frameshift mutations. This is because they shift the codon spots by adding or deleting a nucleotide.
