Help AND NO LINKS- thank you! 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
