[1] The drug molecule also fools the enzymes that help in this process to incorporate this compound in the replication and not uracil, this causes the biological polymer (cancer) not to continue synthesizing. Answered - [Adenine] [Cytosine] [Thymine] [Guanine] are the options of mcq question In RNA, uracil pairs with realted topics topics with 0 Attempts, 0 % Average Score, 0 Topic Tagged and 0 People Bookmarked this question which was asked on Nov 26, 2018 02:17 Family 2 mismatch-specific uracil DNA glycosylase (MUG) from Escherichia coli is known to exhibit glycosylase activity on three mismatched base pairs, T/U, G/U and C/U. A: Blood vessels are an important part of the circulatory system. If you're just rewriting the sequence as it would appear if it were RNA instead of DNA, just sub in U for T and otherwise it's the same. Source(s): neurobiology major. RNA and DNA share three bases: adenine, cytosine, and guanine. When a phosphate attaches to uridine, uridine 5'-monophosphate is produced. When a phosphate attaches to uridine, uridine 5'-monophosphate is produced. [8], Uracil can be used for drug delivery and as a pharmaceutical. b) Uracil is the hydrogen bond acceptor and can form two hydrogen bonds Uracil, aber nicht Thymin bildet ein stabiles Photohydratisierungsprodukt. the relationship between strands of RNA and DNA during transcription is____ complementary. When base pairing with adenine, uracil acts as both a hydrogen bond acceptor and a hydrogen bond donor. *How do you describe a healthy lifestyle habit? It turns into thymine to protect the DNA and to improve the efficiency of DNA replication. At least four different human DNA glyco… abasic site. Uracil can base pair with any of the bases depending on how the molecule arranges itself on the helix, but readily pairs with adenine because the methyl group is repelled into a fixed position. Uracil is the pyrimidine base of the DNA which contains two keto groups at C-2 and C-4 position. It pairs with adenine and is symbolised by U. Our genetic information is stored in the form of DNA, using a four-letter alphabet. It pairs with adenine and is symbolised by U.
