Why do most replication errors occur? O 1. DNA polymerases work very fast and mistakes are inevitable. O 2. DNA repair mechanisms do not work well O 3. DNA replication is a slow and uncommon process. O 4. The hydrogen bonds between base pairs are weak. O 5. DNA ligase often binds incorrect sections of DNA.

DNA replication is semi-conservative, this statement means that Question 6 options: a) the new DNA molecules that are made are not identical to the original DNA molecule. b) the new DNA molecules that are made are only partially DNA since RNA primers are included. c) the new DNA molecules that are made are composed of one strand of the old DNA molecule and one strand of new DNA. d) of the two new DNA molecules made, one is entirely new DNA and one is entirely old new. e) the new DNA molecules that are made have a mixture of old and new DNA in each strand of the DNA duplex, randomly interspersed.
Which of the following is/are true regarding the enzyme primase? a: primase functions during cellular DNA replication. b: without primase activity, DNA polymerase in our cell can NOT begin synthesizing new nucleotide chains. c: primase uses dNTP building blocks d: primase is a polymerase enzyme e: primase functions AFTER DNA helicase activity. Ps: This has multiple answers. thank you.
choices are distruptive replication, semiconservative replication, conservative replication, and dispersive replication
Need help, please. Please answer the following four questions to the image I attached. 1. You digest both plasmids with BamHI and SacI together (a double digest). What size fragments will result? Please indicate the sizes of the expected fragments in basepairs: The large fragment of pNUT is fragment A. This fragment is expected to be ____ bp. 2. The small fragment of pNUT is fragment B. This fragment is expected to be ____ bp. 3. The large fragment of pPOD is fragment C. This fragment is expected to be ____ bp. 4. The small fragment of pPOD is fragment D. This fragment is expected to be ____ bp.

A biochemist isolates, purifies and combines ina test tube a variety of molecules needed for DNA replication. When she adds some DNA to the mixture, replication occurs, but each DNA molecule consists of a normal strand paired with numerous segments of DNA a few hundred nucleotides long. What has she probably left out of the mixture? a.DNA polymerase b. DNA ligase c. Okajaki fragments d. primase
