DNA replication is semi-conservative one strand from each of the initial two strands end up in a daughter strand Each strand serves as a template for a new strand New strand is formed by complementary base-pairing of the correct nucleotide plus formation of a phosphodiester bond View DNA-replication-revised.ppt from BIO 413 at University of Nairobi. DNA Replication •What are the key events of the template model for DNA replication? 5.) 34.2: DNA Replication is Highly Coordinated An Origin for DNA Replication A helicase • Replication involves initiation, elongation, and termination. Vocabulary for ppt 2 Transcription and Translation • Genes Chapter 8.4 and 8.5 • DNA • RNA • Protein • mRNA • tRNA • rRNA • Transcription • RNA Polymerase • RNA bases • Exon • Intron • Amino Acid • Ribosome • Translation • Codon • Anticodon • Genetic Code Chart • Start codon • Stop Codons การจําลองดีเอ็นเอแบบทีต า (Theta mode of DNA replication) 2. f DNA replication DNA structure suggests an obvious replication mechanism Watson and Crick noted that “specific [base]pairing…immediately suggests a possible copying mechanism for the genetic material” the model suggested that each strand could serve as a template for making a … This sequence causes the mRNA to form a stem-loop hairpin structure. • E. colichromosome is circular, double-stranded DNA (4.6x103 kilobase pairs, >1000 bp/sec) • Replication begins at a unique site (origin) • Proceeds bidirectionally until the two replication complexes meet (termination site) DNA Replication Summary Enzymes and proteins involved Process of replication in eukaryotes and … 6.) รูปแบบของการจําลองดี็เอนเอ (DNA replication mode) แบ งได เป 3 นรูปแบบ คือ 1. •DNA polymerases that carry out replication also play another important role •As they assemble new DNA strands, they proof-read and correct errors (base-pair mismatches) •Proof-reading: While creating the complementary strand, if a mismatch occurs, DNA polymerase III may back up, repair, and continue The terminator region of the DNA codes a palindromic sequence. The transcription is finished, and the mRNA is ready to be translated. –helicase unwinds the double helix –the two exposed strands of DNA act as a template for DNA replication –DNA polymerase adds the correct complimentary base pairs to the exposed strands This hairpin structure leads to the dissociation of the RNA-Polymerase from the DNA.
