Cryptozoology is study of animals that are rumoured to exist. (Bigfoot, Loch Ness Monster, etc) It is connected with pseudoscience.

Mythology can refer to myths or the study of myths.

As you can see, the study of fish does not apply to any of the area of studies except for Science. Ichthyology applies to Science, because it is a scientific study is different aspects of various species of fish. This includes history, behaviour, and growth.

2. How could one change in a DNA nucleotide alter the formation of the translated protein
vichka [17]

Answer AND Explanation:

Proteins are formed from the translation of mRNA  to amino acid. Each set of 3 nucleotides make up a codon that codes for a specific amino acid. Frameshift mutations can also impact the formation of the protein.  A change in a nucleotide does not always change the amino acid or protein because some amino acids have more than one set of 3 nucleotides that code for them. Valine, for example, is coded for by GUU, GUC, GUA and GUG. A change in the last nucleotide wouldn't affect the amino acid formed. However,GAG codes for glutamic acid.
