Tourette syndrome (also called Tourette's syndrome, Tourette's disorder, Gilles de la Tourette syndrome, GTS or TS) is an inherited neurological disorder with onset in childhood, characterized by the presence of multiple motor tics and at least one phonic tic, which characteristically wax and wane.n some cases, tics may not be inherited; these cases are identified as sporadic Tourette syndrome (also known as tourettism) because a genetic link is missing. A person with Tourette syndrome has about a 50% chance of passing the gene(s) to one of his/her children.
DNA vs. RNA. Structurally RNA is different from DNA in consisting of ribose as pentose sugar and Uracil as the pyrimidine group. RNA is not double helix as DNA, but it forms similar helical structures by being wound back due to base pairing. Just as in DNA, the bases are hydrogen bonded in RNA in these helical regions. RNA exists as single helix in most regions. The pentose sugar in RNA is ribose and in DNA it is deoxyribose. Deoxyribse has one oxygen atom less on the 5â Carbon of the ribose sugar. Since RNA has few or no base pairs the Chargaff rule of equivalence of Adenine with Thymine and Cytosine with Guanine cannot be extended to DNA.
- DNA has a nitrogenous base called Thymine, but RNA doesn't. Instead, RNA has Uracil. In DNA thymine pairs with adenine, but in RNA uracil pairs with adenine. ... Differences: - DNA is double-stranded, RNA is single-stranded. - DNA contains a pentose sugar Deoxyribose, RNA contains the pentose sugar Ribose. A pentose is a 5-carbon sugar molecule. - DNA is limited to the nucleus, RNA is made in the nucleus, but can travel outside of it. - DNA has a nitrogenous base called Thymine, but RNA doesn't. Instead, RNA has Uracil. In DNA thymine pairs with adenine, but in RNA uracil pairs with adenine. - There is only one type of DNA but 3 kinds of RNA (messenger, transfer and ribosomal RNA) Similarities: - DNA and RNA are made up of monomers called nucleotides.
