Is RNA more fragile than DNA? RNA is generally considered to be less stable or more fragile than DNA because it is susceptible to hydrolysis and degradation by ribonucleases. DNA, with its deoxyribose sugar, is more stable.

What is the ratio of RNA to protein? The ratio of RNA to protein in a cell can vary depending on the cell type and state. On average, RNA makes up about 1-2% of the total cellular weight, while proteins make up a much larger proportion.

How much bigger is DNA than RNA? DNA is typically longer than RNA molecules of the same sequence because DNA molecules contain two complementary strands, whereas RNA is usually single-stranded.

Is RNA as big as DNA? RNA molecules can be similar in size to DNA molecules of the same sequence. However, DNA double helices can be longer because they consist of two complementary strands.

How much RNA is in DNA? RNA is not typically found within DNA molecules. DNA contains deoxyribonucleotides, while RNA contains ribonucleotides. These are distinct molecules.
