'daughter' strands, which requires the addition of new histones.To make things more complicated, one of the two DNA strands can be replicated only in short pieces - called Okazaki fragments - that are joined together afterwards, and so its replication lags behind that of the other strand (...
All base pairs in the genome are replicated during the DNA synthesis phase of the cell cycle, but only some of the base pairs are transcribed into RNA. How is it determined which base pairs of the genome are transcribed into RNA? 在细胞周期的DNA合成期,基因组中所有的碱基对都被复制,但只有...
During which stage of the cell cycle is the DNA replicated? a. Mitosis. b. S. c. G2. d. Cytokinesis. Cell Cycle: The cell cycle is the steps taken during a cells life cycle. The cell cycle is divided into interphase, mitosis and cytokinesis. The...
DNA is the ultimate blueprints for the entire cell. Often referred to as the genetic material of the cell, DNA holds all the information needed for cell structure and function. Answer and Explanation:1 The point of DNA replication is to make two identical daughter copies of DNA. DNA replicati...
In plants, MCM proteins have been implicated in cell division and are responsible for ensuring that the DNA of the cell is replicated only once per cell division. MCM proteins are encoded by a six-member multigene family and they interact with each other to form a complex. MCM proteins are...
The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides....
Accurate chromosomal DNA replication is essential to maintain genomic stability. Genetic evidence suggests that certain repetitive sequences impair replication, yet the underlying mechanism is poorly defined. Replication could be directly inhibited by th
Because of the way the nitrogen bases pair up, the order of the bases in each new DNA strand exactly matches the order in the original DNA strand What determines how DNA is replicated? Nitrogene base pattern Where in the cell does DNA replication take place?
23、on between the newly separated template strands and the unreplicated duplex dna (刚分开的模板链和未复制的双链(刚分开的模板链和未复制的双链dna之间的连之间的连接区称为复制叉接区称为复制叉)leading strand(前导链)前导链)lagging strand(后随链)(后随链)okazaki fragmentreplication fork已复制已复...
DNA methylation The mechanisms that allow DNA methylation to be copied during DNA replication represent one of the best-understood epigenetic systems, and involve specific proteins that recognize CpG hemi-methylated DNA and thereby redeposit DNA methylation on newly replicated DNA. DNA methylation is ma...
