Both DNA and RNA contains the following .?
a.. contain phosphate
Are DNA & RNA both polymer proteins, or is one a monomer?
DNA & RNA are both polymers but not proteins. Proteins are amino acids chained together while DNA & RNA are nucleic acids made up of nucleotides. DNA means deoxyribonucleic acid, and is assembled from 4 nucleotides: cytosine (C), guanine (G), adenine (A) and thymine (T). RNA uses uracil (U) instead of thymine. http://users.rcn.com/jkimball.ma.ultrane...
What do DNA and RNA have in common (what are some ways they are alike)?
Both DNA and RNA are nucleic acid polymers. The monomers of both DNA and RNA are composed of three parts: a phosphate group, a pentose (5-carbon sugar), and a nitrogenous base. Both DNA and RNA use a form of ribose as their sugar (RNA uses ribose itself; in DNA, a single oxygen atom has been removed from the 2' carbon of ribose, to form deoxyribose). Both DNA and RNA use the bases adenine, cytosine, and guanine. Both DNA and RNA undergo complementary base pairing (DNA usually between two different strands, and RNA usually between two regions of a single strand). Both DNA and RNA are synthesized in the 5' to 3' direction.
What are the monomers of DNA and RNA?
Nucleotides or nucleoside monophosphates are monomers of DNA and RNA. However, there are 2 differences in the monomers which form DNA and RNA respectively. The monomers of DNA have 2' H (hydrogen) and base is any of the following: adenine, guanine, cytosine or thymine. While in case of RNA, monomers have 2'OH and any of the following bases: adenine, guanine, cytosine or uracil. The presence of 2'OH (hydroxyl) makes RNA less stable than DNA.(Image: Nucleic Acids )
How does RNA differ from DNA?
A) RNA is double-stranded; DNA is single-stranded B) RNA is a polymer of amino acids; DNA is a polymer of nucleotides C) RNA contains uracil; DNA contains thymine D) In RNA G pairs with T; in DNA G pairs with C E) RNA contains one less -OH than does DNA
What are the differences between DNA and RNA?
DNA statrt with a D RNA starts with R!JUST KIDDING!!!Both DNA and RNA consist of subunits called nucleotides. Each nucleotide contains a sugar molecule chemically bonded to a phosphate molecule, which consists of phosphorus and oxygen atoms bonded together; this complex makes up the sides of the ladder or helix. In DNA, the sugar molecule is called deoxyribose because it lacks an oxygen atom whereas in RNA, the sugar is ribose, which is richer in oxygen. Bonded to the sugar are molecules called nitrogenous bases that connect the two sides of the ladder together; these bases form the rungs of the helix. The bases that make up the nucleotides in RNA consist of guanine, cytosine, adenine and uracil; DNA has the bases guanine, cytosine, adenine and thymine. Only certain bases bond with one another; adenine always binds to thymine in DNA or uracil in RNA, whereas cytosine only binds with guanine.DNA exists naturally as a double helix structure, which looks like a ladder that has been twisted. RNA, on the other hand, consists of a single strand that folds into various shapes. Scientists used to think that RNA, not DNA, was the basis of life because it can also store the information needed to make proteins. After further research, DNA was then heralded to be the blueprint of life because it is chemically more stable than RNA; additionally, because DNA has two strands, even if one strand becomes corrupt, the other strand still can provide a reliable template for making proteins.DNA's only function is to contain the code to make proteins. Almost everything happening inside a cell needs proteins. From the structure of cells to the functioning of enzymes that make certain essential chemical reactions possible, proteins are basic to all life. Organisms need a way to ensure that proteins would be able to be made faithfully, and DNA provides the blueprint for these proteins to be synthesized. Because DNA is unable to leave the cell nucleus, a strand of messenger RNA (mRNA) is made from the DNA template, and this mRNA can travel outside the nucleus. The mRNA arrives at the ribosomes, the cell's protein-making factories, and binds to them. Transfer RNA (tRNA) carry amino acids to the ribosome to bond to the mRNA strand. Ribosomal RNA (rRNA) actually act as part of the ribosome to hold the mRNA strand in place.
How are DNA and RNA similar? How are they different?
they both carry genetic info.... DNA is double stranded and RNA is single stranded (this is just the really common diff.... there are lots more) they both consist of a sugar, nucleotide and a phosphate, but RNA has ribose whereas DNA has deoxy ribose... DNA is ONLY found in the nuclues whereas RNA can be found both within and outside the nucleus....
What are subunits of DNA and RNA? What do they do?
The subunits are the sugar-phosphates and nucleotides (adenine, guanine, cytosine and thymine for DNA, adenine, guanine, cytosine and uracil for RNA). The sugar-phosphate backbone is the out edge of the twisted "ladder" you typically see in drawings of DNA and RNA. It is what holds the molecule together. The nucleotides are the "rungs," and they are what encodes the information in DNA and the instructions in RNA. And, RNA is formed by transcribing the opposite pattern of one strand of DNA, like so: Where adenine matches uracil, thymine matches adenine, cytosine matches guanine, and so on. But DNA and RNA are useless without a whole host of other enzymes and proteins and structures within a cell, and lie outside the scope of this question.
Where are the DNA and RNA located in the cell?
In eukaryotes, like us, the DNA is found in the nucleus of each cell. There is also DNA in the mitochondria, but the DNA that affects our heredity and traits is the one in the nucleus. That's why we each have the mitochondrial DNA genomes of our mothers, not our fathers. In plants, there is also DNA in chloroplasts, packaged in nucleoids and shaped like circular rings. There are also very rare cases of DNA in animal chloroplasts, although very few animals have chloroplasts, so this is an unusual exception. Both chloroplasts and mitochondria are thought to have had an endosymbiotic origin, which means they were a foreign organism that lived in a host cell and became a part of the larger organism as it evolved. You could say the host organism borrowed the genomic data of an organism it imbibed, at least in some cases of endosymbiosis. The mitochondria and chloroplasts are somewhat autonomous regarding genetic instructions. In prokaryotes, which have no nucleus, the DNA is in nucleoids. RNA is much more mobile and found all over the cell. It floats in polymeric fluids in the nucleus and it aligns with DNA to receive information through transcription. Then it leaves the DNA and a portal opens on the nuclear wall, allowing the mRNA to pass. The RNA then goes to the ribosomes where the encoded data is used to create needed proteins, which then carry out tasks. The RNA could be found anywhere in the cell and it is also involved in other RNA-mediated tasks.
Which base is only found in RNA and not in DNA?
Uracil !!!In DNA, four bases have been found. They are adenine (A), guanine (G), cytosine (C) and thymine (T). The first three of these bases are found in RNA also but the fourth which is uracil (U) is absent in it.RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine. Both have the same purine bases i.e. guanine and adenine.Source: Which base is present in RNA but not in DNA
