Answer:
Since, the original DNA sequence has not been provided, the mutation can be an insertion/deletion or a frameshift mutation.
- Mutated DNA
- Frameshift mutation/ insertion or deletion
- All the amino acids changed after the point mutation
Explanation:
Frameshift Mutation:
- A frameshift mutation is the alteration in the reading frame of the DNA due to the addition/deletion of one or two nucleotides.
- This type of mutation moves the mRNA sequence one or two bases forwards or backwards which disrupts the three base codons sequence required for translation into proteins.
- The CT at the end of the sequence is indicative of a frameshift in the DNA reading frame.
- Frameshift mutation affect all amino acids in a polypeptide chain as all codons are moved one or two steps forwards or backwards.

That a person is heterozygous for a certain trait. Rr=heterozygous and RR= homozygous. You can remember this because Hetero= different and homo= same
Answer:
The correct answer is option A.
Explanation:
Robertsonian translocation occurs of 2 acrocentric chromosomes with no problems for the person carrying it in balanced form. In an unbalanced form, it produces chromosome imbalance leads to mental disorder or malformations.
In this translocation p arm or long arm join with other chromosome's long arm, carrier is normal due to the presence of 2 copies of all chromosome arms so there will be all the copies of essential genes.
Thus, the correct answer is - option A.
