Dna has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. one

aspect of dna that allows it to accurately store genetic information is the base pairing from chargaff\'s first rule of the four nucleotide bases. if the a content of a dna molecule is 16%, what are the percentages of the remaining bases?

There are four different bases that make the DNA molecule:
Adenine, Cytosine, Guanine, and Thymine.
Due to chemical properties of the bases, there are two pairs of bases that are complementary, Adenine and Thymine and Guanine and Cytosine.
So, if we have 16% of Adenine, there must be the same amount of Thymine, since they only appear in a pair.
16% of Adenine + 16% of Thymine - 32 %
the rest of the abundance of the bases can be calculated by subtracting the 32% out of the 100%: 100-32 = 68
So, Guanine and Cytosine make up 68% of the bases, and a half of that number is the amount each of the bases has in the total amount. 68/2= 34
16% Adenine -  16% Thymine
34% Guanine - 34% Cytosine

What is the preferred method for assessing heart rate during chest compressions?
Dmitry [639]
An electronic cardiac monitor is the preferred method for assessing heart rate during chest compressions. While a person is performing chest compressions on a patient, he or she is hooked up to the electronic cardiac monitor so that the doctor can see exactly how fast the patient's heart is pumping blood. Cardiac monitoring is the best method do assess this.

guajiro [1.7K]
<span>The ash trees are being cut when the show signs of infestation of the ash borer. Ash borer in particular the Emerald Ash Borer (EAB) is a tiny bug but can really do a great damage to the tree. When the tree is infested with the ash borer, they lay their eggs in the bark of tree, when the eggs hatch the lavas would start eating on the inner tissues of the tree blocking the flow of nutrients and water in the tree that causes the tree’s to death.  If the tree is infested they cut it down, burn and bury the wood to stop the spread of infestation. Ash trees are valued for its strength and elasticity that is often used to make baseball bats, bows, tool handles and other products that needs durable wood.</span>
