Which of the following is the correct sequence of steps

Which of the following is the correct sequence of steps in DNA replication in prokaryotes?

1. RNA primers made, SSBs bind, DNA polymerase synthesizes new DNA, helicase unwinds DNA, ligase joins Okazaki fragments
2. SSBs bind, RNA primers made, DNA polymerase synthesizes DNA, RNA primers removed and replaced with DNA, ligase joins Okazaki fragments
3. SSBs bind, DNA polymerase synthesizes new DNA, RNA primers made, ligase joins Okazaki fragments, RNA primers removed

1. The proof-reading function of DNA polymerase III involves
1. an exonuclease that backs up during replication to remove a misincorporated nucleotide
2. an endonuclease that backs up during replication to remove a misincorporated nucleotide
3. an exonuclease that moves forward one nucleotide
4. an endonuclease that removes several nucleotides within a stretch of DNA
2.  

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

1. a mismatche
2. mutation
4. When a mismatched base pair escapes proofreading during DNA replication, bacteria’s mismatch repair system will…

 

1. send a message for the bacteria to die rather than transmit potentially bad mutations to their descendants
2. remove just the one mismatched nucleotide in the new DNA strand
3. remove a large segment of DNA, including the mismatched nucleotide, from the new strand
