Which of the following would cause an error in dna replication
I don't see any options. But, an error can occur if a DNA polymerase inserts an incorrect base.
A. DNA polymerase checking the DNA
Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. ... Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.

addition of an incorrect nucleotide base in daughter strand or breaks in daughter strand that leads to change in nucleotide sequence of DNA, are known as DNA replication errors.
Mistakes during DNA replication, such as addition of an incorrect nucleotide base in daughter strand or breaks in daughter strand that leads to change in nucleotide sequence of DNA, are known as DNA replication errors.
The enzyme DNA ligase repairs the breaks or irregularities in the DNA molecules, such as joining of Okajaki fragments. Therefore, defects in DNA ligase that take apart chunks of DNA would cause an error during DNA replication.
Thus, the correct answer is 'option B).'
DNA polymerase inserts a wrong base
DNA LIGASE TAKING APART CHUNKS OF DNA - APEX
Unwinding of DNA at the origin and synthesis of new strands, accommodated by an enzyme known as helicase, results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis.
hello which of the following there is nothing!
It would be DNA polymerase pairing A with G
The correct option is A. DNA replication is the process by which two identical copies of DNA are produce from one original, parent DNA. The process occurs in all living organisms and it is the mean through which traits are passed from parents to offspring. A number of mechanisms has been put in place to ensure that base pairs are accurately copied during the process of DNA replication. For instance, pairing adenosine base with guanosine during the replication process will result in an error, which can have very severe consequences, if it is not corrected.
