what are the four differences between rna and dna?
262406
DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Also, DNA is double-stranded and RNA is single-stranded which is why RNA can leave the nucleus and DNA can't. Another thing is that DNA is missing an oxygen.

RNA (Ribonucleic Acid) is a polynucleotide, similar to DNA, one of whose roles is protein synthesis. RNA is structurally different from DNA, in that. It is usually single stranded. It contains the Nitrogenous Base Uracil instead of Thymine. Its Nucleotides contain Ribose sugar, as opposed to Deoxyribose sugar.

However, unlike DNA, RNA is usually a single-stranded molecule. Also, the sugar in RNA is ribose instead of deoxyribose (ribose contains one more hydroxyl group on the second carbon), which accounts for the molecule's name. RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.

RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).

What is the difference in what they do? DNA stores and transmits genetic information. RNA acts as a template for making proteins. DNA is found in the nucleus only.

Differences Between DNA and RNA As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. ... RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.

Which of these is a difference between a DNA and an RNA molecule? - DNA is a polymer composed of nucleotides, whereas RNA is a polymer composed of nucleic acids. - DNA contains uracil, whereas RNA contains thymine. - DNA is usually double-stranded, whereas RNA is usually single-stranded.

DNA has Thymine, where as RNA has Uracil. RNA nucleotides include sugar ribose, rather than the Deoxyribose that is part of DNA. Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein.

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil. The diagram below shows the structure of a DNA nucleotide. The sugar is deoxyribose, and adenine is one of four possible nitrogenous bases.

Like DNA, each RNA strand has the same basic structure, composed of nitrogenous bases covalently bound to a sugar-phosphate backbone (Figure 1). However, unlike DNA, RNA is usually a single-stranded molecule.

The DNA is a double-stranded molecule that has a long chain of nucleotides. The RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

The DNA and RNA Structures Nucleotides simply refer to nitrogenous bases, pentose sugar together with the phosphate backbone. Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).

RNA is somewhat similar to DNA; they both are nucleic acids of nitrogen-containing bases joined by sugar-phosphate backbone. ... DNA has Thymine, where as RNA has Uracil. RNA nucleotides include sugar ribose, rather than the Deoxyribose that is part of DNA.
604597
RNA is different from DNA is three ways: (1) the sugar in RNA is ribose not dioxyribose; (2) RNA is generally single-stranded and not double-stranded; and (3) RNA contains uracil in place of thymine. ... The DNA stays safely in the nucleus, while the RNA goes to the protein-building sites in the cytoplasm -- the ribosomes.

RNA is a polymer with a ribose and phosphate backbone and four different bases: adenine, guanine, cytosine, and uracil. The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine.
