4 Νοε 2018 · Difference Between Replication and Duplication of DNA Definition. Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled.
explain how DNA is replicated accurately. explain how and why damage to DNA is repaired. Living cells must be able to duplicate their entire set of genetic instructions every time they divide. Likewise, multicellular organisms must be able to pass on complete copies of their genetic information to future generations.
There are, however, some common features in the replication of eukaryotes, bacteria, and archaea, and one of these features is that multiple different types of proteins are involved in replicating DNA. First, proteins generally called "initiators" have the capacity to bind DNA at or very near origins of replication.
In this section, we explore how an elaborate “replication machine” achieves this accuracy, while duplicating DNA at rates as high as 1000 nucleotides per second.
Overview. To reproduce, a cell must first copy its genome via DNA replication. In DNA replication, double-stranded DNA (dsDNA) is copied to yield two daughter molecules, each identical to the parent molecule. As in transcription, the new polymer grows 5′→3′.
In this chapter we describe the protein machines that replicate and repair the cell's DNA. These machines catalyze some of the most rapid and accurate processes that take place within cells, and their mechanisms clearly demonstrate the elegance and efficiency of cellular chemistry.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides,...
