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.
What is the difference between dna and rna?
DNA contains deoxyribose sugar (i.e there is not hydroxyl group on carbon 2) RNA contains ribose sugar DNA has the base pairs thymine, cytosine guanine and adenine RNA has the base pairs uracil, cytosine, guanine and adenine DNA is double stranded RNA is almost always single stranded DNA is exclusively found in the nucleus except for small amounts in the mitochondria and the chloroplast RNA is made in the nucleus and travels to the cytosol DNA last for a lifetime RNA last for a short time DNA contains deoxyribonucleotide monophosphates RNA contains ribonucleotide monophosphates
What is not a difference between DNA and RNA?
dna strand has a 5' and 3' end whereas a Rna strand doesn't. dna is double stranded, Rna is single stranded. dna has thymine, RNA has uracil. dna contains deoxyribose, RNA contains ribose.
What is the difference between DNA and RNA?
They are both made up of a 5 carbon sugar, a nitrogenous base and a phosphoric acid (phosphate group). DNA and RNA differ in the types of pentose sugar they contain, DNA contains deoxyribose, where RNA contains ribose. The difference between deoxyribose and ribose is that the hydroxyl group (-OH) at carbon 2 is replaced by a hydrogen atom.
List 3 differences between DNA and RNA?
DNA is double-stranded helix, RNA is single stranded helix. DNA is composed of deoxyribose sugar, RNA is composed of ribose sugar. DNA has Thymine as a pairing to Adenine, RNA has Uracil in place of Thymine as a pairing to Adenine. DNA has the chemical code to be transcribed. RNA is the transcribed product.
What are the differences between DNA, RNA, and mRNA?
DNA = Deoxiribo nucleic acidRNA= Ribo nucleic acid. See, the “Deoxi” from DNA is missing here!mRNA = messenger RNA.Here is a picture showing the molecules. Like said above, DNA is deoxi, as you can see in the blue circles, the DNA has -H, where the RNA has -OHThere are a lot of different RNA types, see below:mRNA is the type that is used for protein synthesis. Each DNA nucleotide gets translated to mRNA nucleotide and three mRNA nucleotides gets transcripted to one peptide. A lot of peptides together make a protein.
State three differences between DNA and RNA?
DNA is double stranded, RNA is single stranded DNA contains deoxyribose sugar, RNA has ribose sugar DNA contains thymine base, RNA has uracil base
What is the difference between DNA and RNA in points?
DNA:i. The 2′ end of the pentose sugar has a -H.ii. It is Double stranded.iii. The nucleotide bases present are as follows: Adenine, guanine, thymine, and cytosine.iv. In the case of eukaryotes, the DNA consists of introns (non-coding regions) and exons (coding regions).v. The pentose sugar is deoxyribose sugar (more specifically, beta-2′-deoxy-D-ribofuranose).RNA:i. The 2′ end of the pentose sugar has a -OHii. It is single stranded.iii. The nucleotide bases present are as follows: Adenine, guanine, uracil, and cytosineiv. They do not have any non-coding sequences.v. The pentose sugar is ribose sugar (more specifically, beta-D-ribofuranose).
