Which direction are new nucleotides added during replication? Where does DNA synthesis begin? In what phase does DNA synthesis occur? What direction does tRNA read mRNA? What direction does RNA primase work in? What is the polarity of DNA synthesis?
What direction does DNA replication read? How does the machinery work? What are key proteins?Directionality of DNA molecules:The DNA strand molecules have a directionality. The strands are described as running anti-parallel to each other. One strand runs from 5' to 3' while...
相斥相,Repulsion phase:连锁遗传中把显性基因和隐性基因联系在一起向后代传递称为相斥相,把不同显性基因或不同隐性基因联系在一起向后代传递称为相引相。 相引相,Coupling phase:不同显性基因或不同隐性基因联系在一起,如图,Bb===Aa 干扰,interference:一个单交换发生后,在它邻近再发生第二个单交换的机会就会...
Split decision: What happens to nucleosomes during DNA replication? J Biol Chem. 2005; 280 :12065–12068. doi: 10.1074/jbc.R400039200. [ Cross Ref ]Annunziato A.T. Split decision: what happens to nucleosomes during DNA replication? J. Biol. Chem. 2005; 280 :12065–12068....
The process of DNA replication occurs in three major steps: the unwinding of the double helix and separation of DNA strands, the priming of the template strand, and the assembly of a new DNA strand. The two strands of DNA uncoil at the site called the origin. The initiation of DNA replic...
Why is interphase the longest phase of the cell cycle? What is the meaning of interphase in biology? What part of the cell cycle is interphase? What is the purpose of interphase? How does interphase prepare cells for mitosis? Can there be mitosis without DNA replication in the S phase? Du...
The short answer to your second question is no, transcription generally does not happen at the same time as DNA replication. In eukaryotic cells, DNA replication occurs during the S-phase of the cell cycle. During S-phase, RNA transcription and protein translation are largely limited to the ...
The growth phases are, as you may have suspected, for the growth of the cell, during the synthesis phase the DNA replication occurs in preparation for the second growth phase. Which stage is the fastest in the cell cycle? For the characteristic cell cycle time of 20 hours in a HeLa cell...
Mitochondrial DNA replication follows a unidirectional process from two distinct origins: the origin of H-strand replication (OH) in the D-loop and the origin of L-strand replication (OL) downstream of OH. OH initiates synthesis of a daughter H-strand, displacing the parental H...
Where does the synthesis of transcription factor proteins occur? What is leading strand in DNA replication? In what organelle does transcription take place? What parts make up the transcription-initiation complex? In what phase does DNA synthesis occur?
