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.
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.
DNA replication: Copying genetic information for transmission to the next generation. Occurs in S phase of cell cycle. Process of DNA duplicating itself. Begins with the unwinding of the double helix to expose the bases in each strand of DNA. from the mediumwill form base pairing via h.
focus on the enzymes that mediate DNA replication. In these descriptions, you will encounter several cases of structure suggesting a particular function. We will point out parallels and homologies between bacterial and eukaryotic replication components. This chapter covers the
3 Ιουν 2020 · Abstract. Central to the function of cellular life is the reading, storage, and replication of DNA. Due to the helical structure of DNA, a complicated topological braiding of new strands follows...
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.
the capacity for replication (self duplication) the capacity to store vast hereditary information in coded form and the capacity to express the phenotypes they control.
