WebbDuring the replication, keto form of 5-BU substitutes for T and the replication of an initial AT pair becomes an A: BU pair (Fig. 9.7A). The rare enol form of 5-BU that pairs with G is the first mutagenic step of replication. In the next round of replication G pairs with C. Thus, the transition is completed from AT→GC pair.

Guanine is a purine nucleobase with a chemical formula of C 5 H 5 N 5 O. Purines are heterocyclic aromatic organic compounds. As a purine, adenine is comprised of two carbon rings: a pyrimidine ring and an imidazole ring. Guanine occurs in both DNA and RNA. It complementary base pairs with cytosine in DNA and RNA via …

Webb14 sep. 2024 · In both DNA and RNA, cytosine pairs with guanine ( C = G) by forming three hydrogen bonds. Since adenine and thymine only have two hydrogen bonds, C-G base pairs are slightly more strongly ... WebbDNA with incorporated 5BU must not replicate.It must be incorporated into DNA in its rare form.It must undergo at least two form changes.*DNA with incorporated 5BU must replicate.CorrectCorrect. 5BU must undergo a form change, but that is not sufficient to cause transition.

WebbThe base analog 5-bromouracil (5BU), which sterically resembles thymine, more readily undergoes tautomerization from its keto form to its enol form than does thymine. 5BU can be incorporated into newly synthesized DNA when it pairs with adenine on the template strand. However, the enol form of 5BU pairs with guanine rather than adenine. Webb23 dec. 2024 · Thymine's base analog is 5BU. The thymine analog 5BU pairs with Guanine while thymine pairs with Adenine. The bromine atom in 5BU can switch between its keto and enol forms. During replication, an A-T pair generates an A-5BU pair when 5BU in keto form replaces the thymine.

WebbIn its rare form, 5BU pairs with guanine. T/F True What are the consequences of having pyrimidine dimers in DNA? These dimers distort the DNA structure and result in errors during DNA replication. Thymine dimers can be repaired by Photoreactivation Repair or Nucleotide Excision Repair. T/F
