What would cause an error in DNA replication?

Answer 1

Possible reasons for errors:

• The original DNA strands never being separated.
• DNA polymerase pairing A with G
• DNA ligase taking apart chunks of DNA

Errors occur more when there are long sections of matching nucleotides called repeats. The polymerase can "hiccup" and read a nucleotide again or skip over it. There are enzymes that check for correct sequences as well. They are either part of the polymerase complex or come along and look to make sure the new and old match.

Answer 2

the correct answer would be DNA ligase taking apart cunks of DNA

Answer 3

if there is an error in DNA replication, there will be a mutation on the gene. An organism can only have up to 3 mutations, or it cannot live. So if there is an error in the replication, you will have a mutation. Sometimes it is nothing at all. Other times it changes the whole genetic makeup, such as a crossing over in the 21st chromosome, you will have Down syndrome. :) -Grace (9th grade Biology student)

Answer 4

Mutations occur and those mutations can cause all sorts of disabilites. There are both harmful and helpful mutations, but more often than not mutations are harmful! So to answer your question, any sort of possible problems can occur if there is an error in DNA replication. Stuff like 6 fingers etc. Mutations occur mostly because the DNA strand is incorrectly matched up!

Answer 5

mutations can occur and cause the DNA to reproduce more on to future generations

Answer 6

Because the copy of the cell can be damaged.

Answer 7

Scientists speculate that these errors are just an accidental mis-pairing.
