point, shift deletion, UV rays, radiations, genetics mutations, gene editing
That is just some method that gene can change within the DNA
DNA ligase is the enzyme that repair irregularities and breaks in the back bone of double stranded DNA. The enzyme function by sealing the repair in the DNA, it seals recombination fragments and it connects okazaki fragments during replication of DNA.
If a mutation reduce the amount of ligase, all the functions of the ligase enzyme listed above will be affected negatively.
Animals with a three-chambered heart would include Amphibians.
- Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
- In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
- This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
- As a result heart's load to deliver oxygenated blood to body is lowered.
Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.
