Nucleic Acid Biochemistry — Flashcards

Hypoxanthine is converted to _____ via xanthine oxidase

Carbamoyl phosphate is combined with _____ to form orotic acid (pyrimidine synthesis)

In base excision repair, base-specific _____ remove the altered base and create an AP (apurinic/apyrimidinic) site

microRNA often leads to the _____ of target mRNA, thus causing decreased translation into protein

RNA polymerase _____ makes mRNA

Xanthine is converted to _____ by xanthine oxidase

The _____ is the site where RNA polymerase II and general transcription factors bind to DNA upstream from a gene locus

In the first step of alternative splicing, the primary transcript (hnRNA) combines with _____ and other proteins to form the spliceosome

Every intron has a 5' _____ site and a 3' acceptor site, which are brought together to form the Lariat-shaped loop

In the first step of pyrimidine synthesis, glutamine and CO2 are combined to form _____ via the enzyme carbamoyl phosphate synthetase II (requires 2 ATP)
