Answer:
order of least damaging is b, a, c and d
Explanation:
The 4 kinds of point mutations here present different consequences after a change of a single base pair. The silent point mutation is the least damaging because the alteration of the nucleotide does not implies on a different codon. Missense and nonsense point mutations will imply on a change of a entire different codon and a change of a entire codon to a stop codon, respectively. The missense could be a less aggressive mutation than a nonsense because the codon change may affect only in a small proportion of the entire protein, but the nonsense can be very aggressive by making the protein smaller than it is. The frameshift can cause severe modifications on the whole final protein because almost every codon might code for a different aminoacid leading to a whole new protein.
Answer:
Explanation:
cardiovascular system is the circulatory system, it permits the circulation of blood and allows for transport of nutrients such as amino acids and electrolytes, oxygen and carbon dioxide gases, hormones, and blood cells in the body.
