Are made up of DNA?

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). But DNA is not the direct template for protein production.

What is DNA in short?

Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism.

Can DNA be seen?

Given that DNA molecules are found inside the cells, they are too small to be seen with the naked eye. While it is possible to see the nucleus (containing DNA) using a light microscope, DNA strands/threads can only be viewed using microscopes that allow for higher resolution.

What would happen if DNA get damaged?

While DNA damage is distinguished from mutation, mutation can result from unrepaired DNA. While most DNA damage can be repaired, such repair systems are not 100% efficient. Un-repaired DNA damage accumulates in non-replicating cells, such as neurons or myocytes of adult mammals, and can cause aging.

What does pure DNA look like?

DNA is a water-soluble acid, and the usual extraction process results in something that looks to the naked eye like clumps of very thin, limp noodles — or soggy cotton candy — floating in the tube.

What are the advantages and disadvantages of DNA?

Using DNA profiles to determine paternity

Advantages	Disadvantages
DNA profiles can be used to place suspects at a crime scene	It is possible to plant DNA at a crime scene giving false evidence, or an innocent person’s DNA might be at the scene even though they had nothing to do with the crime

What are the benefits of DNA?

DNA testing can be used to determine paternity, help adopted children identify their biological families, and ensure relationships in the case of inheritance disputes. Life is complicated, but DNA testing doesn’t have to be. Keep reading to learn more about the benefits of DNA testing.
