Answer:
<em>The above statement is false.</em>
Explanation:
<em>When a single nucleotide is changed at a particular position of the nucleotide sequence, then this change will result in the formation of a faulty protein. </em>
<em>This is because that particular position of the genetic sequence is associated with the formation of a particular protein. All the other proteins formed will be normal. </em>
<em>Hence, we cannot attribute all existing changes between the cichlid and coelacanth/frog on this single nucleotide change.</em>
However, if instead of replacement of a T with a C, an addition or deletion had been made, then the entire genetic code would have been altered. This would have resulted in more number of faulty proteins being formed.
Lymphocytes or natural killer
is one of the component of innate immune system where it acts as defense
mechanism of the body that are always present to mobilize and fight bacteria,
viruses and microbes at the site of infection.
Moreover, innate immune
system also refers to non-specific recognition of certain molecular
shapes on pathogens. Other components of innate immune system includes physical epithelial
barriers, phagocytic leukocytes, dendritic cells, and circulating plasma
proteins.
