Answer:
The genetic code is degenerate.
Explanation:
The genetic code is degenerate: there are 64 triplets of different codons (sequence of three bases of mRNA that codes for a certain amino acid) and 20 amino acids. That is, an amico acid can be encoded by more than one codon.
With chromosomes crossing over frequently, it's more likely that genetic defects will occur in offsprinfg.
Answer:
Parallel veins in the leaf
Explanation:
The leaf veins run parallel to one another.
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.
