The answer is Lionfish
are native to the tropical Pacific. There are no natural water routes of warm
water between the Pacific and Atlantic oceans.
Invasive species is a species that colonizes an environment
in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally
found in the indo-pacific, which is their
native environment. However, their presence
in the eastern United States has have threatened
the ecosystem of the region. The fish has decimated fisheries and reef
ecosystem since they also don’t have natural predators in the region. Therefore,
their population explodes unchecked.
Ans.
DNA acts as genetic material in all living organisms that store and transmit genetic information from one to next generation. DNA sequence carries instructions for the expression of genes to make proteins, responsible for different phenotypic characters of individuals.
The DNA, first synthesizes mRNA molecule that carry information for the protein synthesis, in the form of codons and code for a specific polypeptide chain or protein.
The sequence present in DNA determines the amino acid sequence in protein encoded by the DNA. Change in DNA sequence affects gene expression as it leads to change in mRNA sequence, and thus, change in sequence of amino acid of the resulting protein.
