What base is found in DNA but not in RNA? What does RNA primase do in DNA replication? What are the base pairing rules for RNA? What are adenine, guanine, cytosine and thymine? Which base is found only in RNA? In a DNA molecule, which of the following does cytosine pair with? a....
What does RNA primase do in DNA replication? What molecules make up the backbone of the RNA molecule? What are the 3 types of RNA and what are their functions? What way is RNA used other than making protein? Does this use involve double-strand RNA or single- ...

2、染色体真核生物染色体dna有多个复制起始有多个复制起始 点,同时形成多个复制单位,点,同时形成多个复制单位, 两个起始点两个起始点 之间的之间的dna片段称为片段称为复制子复制子(replicon)。 2. 复制叉复制叉 (replication fork) 复制时双链打开,分开成两股,新链复制时双链打开,分开成两股,新链 沿沿 着张...
亲代DNA的两股链解开后,可分别作为模板进行复制。 3.3引发体和RNA引物引发体(primosome)由引发前体与引发酶(primase)组装而成。引发前体是由若干蛋白因子聚合而成的复合体。在原核生物中,引发前体至少由六种蛋白因子构成。蛋白i、蛋白n、蛋白n”、蛋白dnaC与引物预合成有关,蛋白n’与蛋白dnaB与识别复制起始点有...

Effect of 4-quinolones and novobiocin on calf thymus DNA polymerase alpha primase complex, topoisomerases I and II, and growth of mammalian lymphoblasts. The influence of ciprofloxacin, nalidixic acid, norfloxacin, novobiocin, and ofloxacin on elements of eucaryotic DNA replication was investigated in...
▪前导链的合成：由DnaG（primase）在复制起始位点附近合成一个10-60nt的RNA引物，然后由polII把dNTP加到该引物上。滞后链的合成：产生Okazakifragments，消除RNA引物并由DNApolI补上这一小段DNA序列，由DNALigase把两个片段相连。3.DNA链的终止 ▪当子链延伸达到terminusregion（ter，带有多个20bp序列）时，DNA...
DNA Polymerases DNA polymerases catalyze the synthesis of a newDNA strandon a single-stranded DNA template. Both prokaryotic and eukaryotic cells contain multiple types of DNA polymerases that are involved in replication, recombination, and repair. Among these are the replicative DNA polymerases, which...
