Web1. What is the DNA replication fork? It is the DNA bound inside the DNA polymerase active site. It is the binding site on the chromosome for DNA polymerase. It is the site where the leading and lagging strands meet on chromosome. It is the site where the DNA helix opens to two single DNA strands. It is the DNA. Question: 1. WebEach replication fork travels at 500 nucleotide pairs per second in bacterial cells. You should know that there are 10 base pairs per turn of the DNA helix. If topoisomerase was …
DNA and RNA Basics: Replication, Transcription, and Translation
WebWhen a double helix of DNA is replicated, two complete helices are formed. Together, these helices are called sister __________. Each new daughter cell receives one of the sister chromatids. After the chromatids separate, each is considered a new chromosome. At the end of cell division, each new cell contains 23 pairs of chromosomes. WebJun 22, 2024 · Replication: Doubling Up on DNA. Illustration from A&P 6. Replication of a cell’s DNA occurs before a cell prepares to undergo division—either mitosis or meiosis I. It takes place in three(ish) steps. DNA unwinds from the histones. An enzyme called DNA helicase opens up the helix structure on a segment of DNA, breaking the bonds between … northern vulture ff14

WebEach replication fork travels at 500 nucleotide pairs per second in bacterial cells. You should know that there are 10 base pairs per turn of the DNA helix. If topoisomerase was defective, then the DNA ahead of each fork would have to rotate at nearly 3000 revolutions per minute, to prevent the DNA from tangling. True.
