WebIf the DNA synthesis at a replication fork occurs at a rate of 100,000 nucleotides per minute, how much time will theta replication require to completely replicate the molecule, assuming that theta replication is bidirectional? How long will replication of this circular chromosome take by rolling-circle replication? WebDuring meiosis, DNA will replicate zero times, as the goal of meiosis is to produce gametes and separate DNA into four daughter cells. Does DNA replication occur in meiosis 1 or 2? Meiosis II begins with the 2 haploid cells where each chromosome is made up of two connected sister chromatids.

WebTherefore, if we have a gene that is 1200 nucleotides long (which is about average), it will take ~2 minutes to transcribe into 1200 nucleotides of mRNA and ~20 seconds to translate that into a 400 amino acid protein. Bacteria actually start translating the mRNA before they've finished transcribing it.
