Question:
Which of the following is the correct sequence of steps in DNA replication in prokaryotes?
- RNA primers made, SSBs bind, DNA polymerase synthesizes new DNA, helicase unwinds DNA, ligase joins Okazaki fragments
- SSBs bind, RNA primers made, DNA polymerase synthesizes DNA, RNA primers removed and replaced with DNA, ligase joins Okazaki fragments
- SSBs bind, DNA polymerase synthesizes new DNA, RNA primers made, ligase joins Okazaki fragments, RNA primers removed
- The proof-reading function of DNA polymerase III involves
- an exonuclease that backs up during replication to remove a misincorporated nucleotide
- an endonuclease that backs up during replication to remove a misincorporated nucleotide
- an exonuclease that moves forward one nucleotide
- an endonuclease that removes several nucleotides within a stretch of DNA
During replication, a DNA polymerase mistakenly incorporates a C nucleotide in the new strand opposite a T nucleotide in the template strand. This is called
- a mismatche
- mutation
- When a mismatched base pair escapes proofreading during DNA replication, bacteria's mismatch repair system will...
- send a message for the bacteria to die rather than transmit potentially bad mutations to their descendants
- remove just the one mismatched nucleotide in the new DNA strand
- remove a large segment of DNA, including the mismatched nucleotide, from the new strand
