The nitrogenous base adenine pairs with what other base to form a base pair?

Select all correct information regarding telomeres.

• Telomeres are a string of repeated sequences in DNA.

• They prevent chromosomes from accidentally attaching.

• If missing, they are added by telomerase

• All of these are true

Errors in replication can be mended by:

• Okazaki fragmentation

• Proofreading

• Mismatch repair

• Removal of the original DNA from the cell

The polymerase chain reaction allows scientists to create several copies of a short DNA sequence in a test tube. Choose all correct ingredients to this reaction.

• A sample of DNA to be the template

• The four dNTPs

• Two short, artificial primers

• A DNA polymerase and salts to neutralize the pH
