Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.
Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.
<u>Answer:</u>
<em>Dependent variable are those variables that changes with the change in variables that affects it.</em>
<u>Explanation:</u>
Dependent variable responds or gets affected to change. They are not constant. It can be possible that dependent variable is relying on independent variable as independent variable does not change with change of any of the factor in an experiment.
Sometimes, mentioning not the units leads to insufficient data of the variables. A constant is something whose value cannot be changed and is used for comparison purpose. According to the question, Rose is constant, height is dependent variable , different types of soil are independent variable.
The role of a Detrivore is to help recycle the nutrients in the soil. They break down complex proteins, and other materials so the answer is A. to decompose dead animals.
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is x, you need to have xx to have hemophilia. The father must have the genotype<span> Yx and the mother has the have Xx or xx.
