The ratio of indicates the purity of nucleic acid.For pure DNA it should lie between 1.8-2.0.Whereas for RNA it should be greater than 2.
This is calculated for DNA using the given values of absorbance-
= 2.71
As the value is greater than 2.0,it reflects the RNA contamination in the sample.
Answer:
<h3>Enzymes are typically which type of biomolecule?</h3>Enzymes are protein biomolecules.
Enzymes are bound to specific substrate/s and act as <u>catalysts</u> that makes chemical reactions faster, such as breaking down lactose to smaller units of glucose, which is accomplished by lactase.
<u>Cofactors (metal ions such as iron, zinc) and coenzymes (organic molecules like vitamins)</u> may be needed to initiate chemical reactions.
<h3>Describe the effects that enzymes can have on substrates.</h3>After creating the <u>enzyme-substrate complex</u> through <u>induced fit</u>, enzymatic products are seen after the reaction. The <u>substrates may be consumed during the process or preserved</u> to be used again.
For example, these enzymatic products may be used for feedback inhibition to control the chemical reaction and production of a certain hormone.
