DNA polymerase I has 5′–3′ polymerase activity, 5′–3′ exonuclease activity, and 3′–5′exonuclease activity necessary for DNA replication. Mutations in the gene that encodes DNA polymerase I may cause the enzyme to lose these activities.
Match the consequence of a loss‑of‑function mutation in DNA polymerase I to the corresponding lost activity.

a) Lost 5′–3′ polymerase activity
b) Lost 5′–3′ exonuclease activity
c) Lost 3′–5′exonuclease activity

1. No RNA primer removal during DNA replication
2. Decreased polymerase fidelity
3. No double helix denaturation
4. Unstable strand separation within the replication bubble
5. No DNA synthesis to fill gaps caused by removing RNA primers

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
