Answer:
Lysozyme is an enzyme that breaks down bacterial cell walls and is found in your tears, mucus, and saliva. A mutation occurs in the gene for lysozyme that results in a lysine (a positively charged amino acid) being substituted for an arginine (also a positively charged amino acid). Do you think that the mutant lysozyme will function similarly to the normal lysozyme?
No, because all changes in protein primary sequence result in functional differences
Explanation:
Protein sequence are known to be complimentary to each other, slight changes or sudden changes would affect the function as well as those work in antagonizing way with one another.
Three examples of marine genetically engineered organisms are:
1. AquAdvantage salmon is genetically engineered Atlantic salmon modified in order to achieve fast growth. A growth hormone-regulating gene of Pacific salmon is introduced in the genome of Atlantic salmon.
2. Grass carp was also modified by scientist in order to enhance its protection from contagious diseases. It has been modified with a transgene coding for lactoferrin (antibacterial function). So, the, survival rate of the modified Grass carp was doubled comparing to nonmodifeied fish.
3. Zebrafish is the most commonly used for modification because it has 1-cell embryo, with clear chorion so it is easy to be micro-injected with transgenic DNA.
The answer is A. point mutation which does not change the amino acid. A point mutation is a mutation of gene in which a single nucleotide is changed from the sequence. In this case, the amino acid was replaced by the same amino acid in which there will be no effect on the product of the sequence. This will not alter the replicated DNA, Product that will be produced will be essentially the same.
