Which RNA base pairs with the adenine in DNA? What form of RNA carries instructions from the nucleus to the ribosome? What types of RNA are involved in translation? What is the secondary structure of transfer RNA? What does RNA primase do in DNA replication?
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....
These findings result in a revised model of lagging strand DNA synthesis where the primase remains as part of the replisome after each successful cycle of Okazaki fragment synthesis. A delay in primer transfer results in an increased probability of the primase dissociating from the replication fork....
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...
Checkpoint induction did not require new DNA synthesis on the unwound template strand but did require RNA primer synthesis by primase. These findings identify the RNA portion of the primer as an important component of the signal that activates the replication checkpoint. 展开 ...

近日,清华大学生命中心孙前文实验室在Nature Communications杂志上发表了题为Primase promotes the competition between transcription and replication on the same template strand resulting in DNA damage的研究论文,揭示了拟南芥叶绿体DNA复制引物酶促进叶绿体基因组的转录复制竞争和R-loop积累,从而诱发叶绿体基因组断裂的分子...
2、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 着张开的模板生成,复制中形成...
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...
Explain why DNA polymerase can continuously add fragments onto the leading strands 3'-5', but cannot do the same for the lagging strand. Why does primase make RNA and not DNA? Why does DNA need RNA? When using Exofast RT-PCR kit ( MASTER MIX...
