Answer;
- DNA
-Some additional proof of the endosymbiotic theory includes the similarity in DNA between bacteria and mitochondria and cyanobacteria and chloroplasts.
Explanation;
-According to the endosymbiotic theory; mitochondria and chloroplasts contain their own circular DNA, similar to DNA in Bacteria, Both mitochondria and chloroplasts are surrounded by two membranes: inner and outer membrane, mitochondria are about the same size as bacteria and also mitochondria appear to have been derived from purple bacteria and chloroplasts derived from photosynthetic bacteria.
Science means to know. Biology is the study of living things.
You understand a lot more of the function of the body (EMT, healthcare, diseases, etc.)
animals (veterinary work,etc.) You will understand the intro into genetics, and the ways in which the sun and plants directly influences our entire world.
Biology is a form of science that is pretty broad, and at the same time a form of science you can use in every day life of understanding the basic things that happen around you (in culture, family, news, environment, behavioural, etc.)
Biology is also a great way to get your feet wet into basic science- a launching pad for chemistry, physics, etc. Hope this helped. :)
EDTA inhibits the activity of DNase during DNA isolation process.
DNase is an enzyme which degrades DNA using divalent metal ions like Mg^{2+} . These metal ions act as cofactor for the proper functioning of DNase.
EDTA chelates the divalent metal ions and thus does not allow DNase to access them.
Therefore in this way DNA is prevented from degradation during its isolation.
