RNA contains paired bases and DNA does not
A DNA molecule has the shape of a double-stranded helix.
A DNA molecule is made up of deoxyribose sugar while RNA is made up of ribose sugar. A DNA molecule is double stranded whilst a RNA molecule is single stranded. A DNA molecule only contains the bases; Adenine, Thymine, Cytosine and Guanine. However a RNA molecule contains the bases; Uracil, Thymine, Cytosine and Guanine. DNA is only found in the nucleus of a cell, while RNA is found in the cytoplasm.
DNA usually comes as a double-stranded molecule, although there are many exceptions. For example, the DNA virus parvoviruscontains a single-stranded DNA genome.
dna is double stranded and rna is single stranded
1) DNA is a two-stranded molecule. RNA is a single strand molecule. 2) DNA contains deoxyribose molecules in its backbone, while RNA has ribose in its molecular structure. 3) DNA molecule contains Thymine as one of its purine bases. RNA molecule contains Uracil instead of Thymine.
RNA is a single stranded molecule while DNA is a double stranded molecule. RNA contains the sugar ribose while DNA contains the sugar deoxyribose. The difference between ribose and deoxyribose is ribose has one more -OH group than deoxyribose, which has -H attached to the second carbon in the ring.
DNA is double stranded and RNA is single Stranded.
Most strands of RNA are single stranded, tRNA, mRNA and rRNA however dsRNA is double stranded, this form of RNA is found usually in viruses. See related links
Like DNA, RNA contains the bases adenine (A), cytosine (C), and guanine (G); however, RNA does notcontain thymine, instead, RNA's fourth nucleotide is the base uracil (U). Unlike the double-stranded DNAmolecule, RNA is a single-stranded molecule.
DNA molecule is normally double stranded
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
1. DNA is double stranded, RNA is single stranded (only true in cells - viruses can also use single stranded DNA and double stranded RNA) 2. DNA contains deoxyribose sugar, RNA contains ribose sugar 3. DNA contains thyamine base, RNA contains uracil base
1 - Ribose contains a pentose sugar named 'ribose' in its nucleotides, while DNA contains 'deoxyribose' which is the same, except that it is missing on oxygen atom. 2 - DNA has a nitrogenous base names Thymine (which bonds with adenine) while in RNA, this base is replaces by Uracil. 3 - DNA is a double stranded molecule, while RNA is a single stranded molecule.
DNA is double stranded and RNA is single stranded.
The two bases that are present in equal amounts in a double stranded DNA molecule are cytosine and guanine. Cytosine pairs with guanine in A DNA molecule.
Deoxyribonucleic acid, or DNA.
