WebEukaryote - linear chromosome - multiple replicons - multiple origins of replication - histones Which DNA sequence pairing is the most stable? GCGTGCAC CGCACGTG Doubled-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5' to 3' direction, while the other is oriented in the 3' to 5' direction. True The replisome is a complex molecular machine that carries out replication of DNA. The replisome first unwinds double stranded DNA into two single strands. For each of the resulting single strands, a new complementary sequence of DNA is synthesized. The Total result is formation of two new double … See more For prokaryotes, each dividing nucleoid (region containing genetic material which is not a nucleus) requires two replisomes for bidirectional replication. The two replisomes continue replication at both forks in … See more The replisome is a system in which various factors work together to solve the structural and chemical challenges of DNA replication. … See more Replication stress can result in a stalled replication fork. One type of replicative stress results from DNA damage such as inter-strand cross-links (ICLs). … See more • Pomerantz RT, O'Donnell M (April 2007). "Replisome mechanics: insights into a twin DNA polymerase machine". Trends Microbiol. 15 (4): … See more For eukaryotes, numerous replication bubbles form at origins of replication throughout the chromosome. As with prokaryotes, two replisomes are required, one at each … See more Many of the structural and chemical problems associated with DNA replication are managed by molecular machinery that is highly conserved across organisms. This section … See more Katherine Lemon and Alan Grossman showed using Bacillus subtilis that replisomes do not move like trains along a track but DNA is actually fed through a stationary pair of replisomes located at the cell membrane. In their experiment, the replisomes in B. … See more
