Does a small change in DNA, like a missing nucleotide always affect the protein?
Pachacha [2.7K]

yes because they way a protein is made has to do with the order of nucleotides in its corresponding dna strand. One amino acid corresponds to a  group of three nucleotides (codon) so if a nucleotide is missing it shifts the way the dna is read (meaning the codons are no longer the same) and the amino acids are different, which results in a completely different chain of amino acids. However, since more than one codon can code for the same amino acid, if one nucleotide is simply replaced by another but the amino acid that is coded for stays the same then the protein is not changed.

A pig that has internal parasites has ( )living in its intestines
Delicious77 [7]

A pig that has internal parasites living in its intestines is what's known as parasitism.

This relationship is one of the three forms of symbiosis. Relationships involving two organisms in which at least one of the organisms benefits. The three kinds of symbiotic relationships are :

  • Mutualism
  • Commensalism
  • Parasitism

Mutualism is the symbiotic relationship in which one organism benefits and the other does as well. An example of this can be found in our oceans, in that some fish will stick to larger sharks and clean their body of parasites in return for protection and a steady food supply.

Commensalism is the relationship between two organisms in which one will benefit while the other is not affected. One such case can be observed when birds build their nests on tree branches. The bird will benefit from the structure of the tree without causing it any harm.

Finally, parasitism is, as you may expect, is a relationship in which one organism benefits while the other Is harmed. The case given is an example of this in that the parasite will feed off of the nutrients consumed by the pig, who will, in turn, become malnourished and face health issues.
