This took so long, and it didn't come out the way I wanted it to be set up. I really needed help, but I hope someone will understand what I was trying to put :(
Based on the given image and the explanation provided, there are several observations we can make:
1. Original DNA code for an amino acid sequence:
The original DNA sequence is represented by the bases: C A T C A T C A T C A T C A T C A T. These bases determine the order of amino acids in the resulting protein.
2. Amino Acid Sequence:
The amino acid sequence derived from the original DNA code consists of a repeating pattern: Histidine (His) - Histidine (His) - Histidine (His) - Histidine (His) - Histidine (His) - Histidine (His).
3. Insertion of a single nucleotide:
There is an insertion of a single nucleotide (Adenine - A) in the DNA sequence. This alteration is represented by the DNA bases: C A T C A T C A T A C A T C A T C A.
4. Altered Amino Acid Sequence:
As a result of the insertion, the amino acid sequence is changed. The new sequence becomes: Histidine (His) - Histidine (His) - Histidine (His) - Threonine (Thr) - Serine (Ser) - Serine (Ser) - Serine (Ser). This change introduces an incorrect amino acid sequence.
5. Incorrect Amino Acid Sequence:
The insertion of the single nucleotide leads to an incorrect amino acid sequence, which may produce a malfunctioning protein. The original pattern of Histidine (His) is disrupted, and different amino acids (Threonine and Serine) are introduced.
To summarize, the image provides a comparison between the original DNA code for an amino acid sequence and an altered sequence due to the insertion of a single nucleotide. The alteration results in an incorrect amino acid sequence, which could potentially lead to a malfunctioning protein.
