Why is DNA considered a better genetic material than RNA?

Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.

What are the advantages of DNA over RNA?

With the exception of certain viruses, DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction.

Why is RNA unstable than DNA?

Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation.

Why is DNA and not RNA the genetic material in majority of organisms?

DNA and not RNA is the genetic material in majority of organisms.” The -OH group in the nucleotides of RNA is much more reactive and makes RNA labile and easily degradable thus DNA and not RNA acts as genetic material in majority of organisms.

What are the disadvantages of RNA?

The extra oxygen atom in RNA makes it less stable when compared to DNA. Reactivity: Due to the same reason as above, RNA is a very reactive molecule. A genetic material should not be very reactive and should remain stable.

What are the three structural differences between RNA and DNA?

So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.

What are the advantages of RNA?

In a number of clinically important viruses RNA, rather than DNA, carries the viral genetic information. RNA also plays an important role in regulating cellular processes–from cell division, differentiation and growth to cell aging and death.

What are limitations of DNA microarray technology?

The most significant disadvantages of microarrays include the high cost of a single experiment, the large number of probe designs based on sequences of low-specificity, as well as the lack of control over the pool of analyzed transcripts since most of the commonly used microarray platforms utilize only one set of …
