The answer to this question is option B for sure.
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.
Answer:
There are two paths of a drop of blood leaving the human heart. First, the deoxygenated blood leaves the heart and second, oxygenated blood leaves the heart,
Explanation:
Deoxygenated blood leaves the heart through an artery called pulmonary artery which take this blood to the lungs. After that, oxygenated blood carries from lungs to the heart through pulmonary vein. The oxygenated blood in the heart leaves the heart through aorta and distribute this blood in all parts of the body.
