Help Suppose a mutation were to occur to the mRNA sequence in Bonus question #1, in which an extra Uracil is added to the mRNA molecule between the 6th and 7th position. This mutation would cause a change to the codon sequence that . Changes such as these can result in variations that could be . 

First blank:

1. Causes the removal of the start codon, therefore no protein will be built

2. Results in the addition of extra amino acids to the protein

3. Causes a stop codon to end the amino acid chain to early

4. Results in no change to the amino acid sequence

Second blank:

1. Harmful to the organism

2. Neither harmful nor beneficial to the organism

3. Beneficial to the organism

4. All of the above

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
