DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes<span>, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.</span>
Answer: insertion
Crossing over is when homologous* chromosomes exchange genes, resulting in gene combinations.
Deletion is when a base pair is deleted from DNA. Insertion is when a base pair is added to DNA. Both insertion and deletion are serious because every amino acid beginning at the mutation will most likely be incorrect. This will lead to a nonfunctional protein.
Base-pair substitution is a substitution of one base pair for another in DNA. The effects of this may be a silent** point, missense*** point, or nonsense**** point.

<em>*A pair of matching chromosomes. They have the same genes but can have different versions.</em>
<em>**A special case where no amino acids are affected.</em>
<em>***Affects one animo acid. The whole protein structure and function may or may not be disrupted. </em>
<em>****Results in a stop codon that shortens the protein.</em>
Answer: the canine parvovirus infection is digestive
giardiasis is also digestive
tracheobronchitis is respitory
feline viral rhinotracheitis respitory
coccidios im pretty sure that is digestive
Explanation:
The number of chromosomes remain the same, 46. Although they are replicated, the two sister chromatids in one chromosome are still considered one chromosome.
Answer:
Leaf cuttings, in which a leaf is placed on moist soil. These have to develop both new stems and new roots.
Explanation:
Some leaves will produce one plant at the base of the leaf. In some species, multiple new plants can be produced at many places on one leaf, and these can be induced by cutting the leaf veins.
