- . DNA polymerase requires both a template, to be copied, and a primer, which provides a 3' hydroxyl from which polymerase can extend. Yet this molecule supports DNA polymerase activity. Explain. PTGACACAGGTTTAGCCCATCGATGGG-OHarrow_forwardIn experiments using polymerase chain reactions (PCR), it is often more difficult to amplifythrough regions of DNA that are high in GC content versus those regions that are either lower inGC content or are AT-rich. Based on your knowledge of DNA structure, explain why.arrow_forwardA DNA fragment with the following base sequence has some cytosine bases that are methylated (indicated by C*) and others that are unmethylated. To determine the locations of methylated and unmethylated cytosines, researchers sequenced this fragment both with and without treatment with sodium bisulfite. Give the sequence of bases that will be read with and without bisulfite treatment. —ATCGC*GTTAC*GTTGC*GTCA—arrow_forward

- A solution containing single stranded DNA with the sequence 5’ATGGTGCACCTGACTCCTGAGGAGAAGTCTNNNNN’3 undergoes DNA replication in vitro in the presence of all four nucleotides plus an amount of dideoxyadenosine triphosphate sufficient to compete for incorporation with deoxyadenosine triphosphate. How many and what DNA fragments are expected?arrow_forwardWhich of the following statement(s) is/are false/incorrect? You may select multiple options, if necessary. ☐ Experiments support bidirectional movement of multiple replication forks at eukaryotic chromosomes. O Mg++ ions play important roles during DNA synthesis Synthesis of DNA is semi-conservative ✔ Beta clamp reduces DNA polymerase processivity ✔ DNA polymerase III uses ATP as a source of energy to drive the polymerization reaction forward O Tautomers enhance chances of correct nucleotide incorporation during DNA synthesisarrow_forwardThe partial sequence of one strand of a double-stranded DNA molecule is5′ – – – GACGAAGTGCTGCAGAAAGTCCGCGTTATAGGCATGAATTCCTGAGG – – – 3′The cleavage sites for the restriction enzymes EcoRI and PstI are shown below.Write the sequence of both strands of the DNA fragment created when this DNA is cleaved with both EcoRI and PstI.
