Discuss the similarities and differences between DNA replication in eukaryotes and prokaryotes State the role of telomerase in DNA replication Eukaryotic genomes are much more complex and larger in size than prokaryotic genomes. Eukaryotes also have a number of different linear chromosomes. The human gen...
DNA replication raises several topological questions. i) How did the two parental strands uncoil in spite of the restriction imposed to their rotation either by DNA circularity or by the barriers which segregate the chromosome into topologically independent domains? ii) How is tangling of the two ...
DNA Replication in Prokaryotes and Eukaryotes DNA replication is a process in which the genetic material of a cell, in this case, the DNA makes an exact copy of itself and the process is controlled by the enzyme DNA polymerase. In mammals, the rate of replication is around 50 nucleotides pe...
一、由单链断裂导致的复制叉坍塌(replication fork collapse)或由DNA复制受阻导致的复制叉断裂(replication fork breakage)是造成DSB的重要原因(复制叉坍塌或断裂几乎在E.coli的每个细胞周期中都会自然发生。在静止期E.coli中,复制叉可以R环为基础组建,并可在基因组中常见的自发单链断裂处坍塌。)。单链断裂可由单链...

DNA Replication in Eukaryotes Eukaryotic genomes are much more complex and larger than prokaryotic genomes and are typically composed of multiple linear chromosomes (Table 2). Thehuman genome, for example, has 3 billion base pairs per haploid set of chromosomes, and 6 billion base pairs are insert...
注:①“非编码损伤”(noncoding or replication-blocking lesions)是指对DNA复制构成明显阻碍的DNA损伤。那些对DNA复制没有明显阻碍但可导致点突变率显著提升的DNA损伤被称为“错码损伤”(miscoding lesions)。(15)本文在讨论TLS时,只涉及“非编码损伤”。
Compare cellular DNA replication to PCR replication. Describe the differences between prokaryotes and eukaryotes in DNA replication: 1) replication, 2) elongation and 3) termination. Compare and contrast DNA and RNA in terms of structure and function. ...
