The eukaryotic DNA replication takes place in the cell nucleus and only occurs in the S phase at many chromosomal origins. Similar to prokaryotic DNA replication, eukaryotic cells also use the semi-conservative process of replication but there are multiple origins of replication. The Steps of the ...
DNA replicationoccurs in the nucleus because DNA is located in the nucleus, andtranscription, the process of creating a temporaryRNAcopy of the DNA, also occurs in the nucleus for the same reason (Fig. 3.14). A complex oftranscription factorproteins binds the DNA immediately upstream of the ge...

E. takes place in the nucleus of the cell. During DNA replication what will happen? Transcription happens (in the nucleus/out of the nucleus). For replication to occur, what chemical bonds in DNA molecules must be broken down? Where does DNA replication start? Is it the same for pr...
DNA replication in eukaryotes is a conserved system that only allows for DNA replication to occur once throughout each cell cycle. The replication of chromosomal DNA in eukaryotes is critical for the duplication of a cell and is required for the maintenance of the eukaryotic genome. Steps in ...

Three-dimensional rendering of FIB–SEM data from cell shown in Fig. 2e,f and Supplementary Video 1 (see also Fig. 2g). TFAM+, cGAS+, TOM20− and LC3− structures (purple), mitochondria (blue) and the nucleus (green) were segmented and overlaid onto the FIB–SEM data....
DNA replication is a biological process that involves the duplication of double-stranded DNA (dsDNA) molecules. A dsDNA molecule consists of two antiparallel strands that are joined with each other by hydrogen bonds. During replication, each strand serves as a template strand ...
A homologue of the PDH45 was isolated fromMedicagosativa(alfalfa), referred to asM. sativahelicase 1 (MH1). When the onion epidermis was transiently transfected by the 35S::MH1-GFP construct, it showed that MH1 was localized in the nucleus of the roots, stems, and leaves of alfalfa. Its ...
