The DNA, mRNA and tRNA are the essential nucleic acids that initiate protein synthesis. The DNA contains the genetic code of our human body in the form of chromosomes. It is composed of nucleic acids like uracil (U), guanine (G), adenine (A) and cytosine (C). The messenger RNA or mRNA carries this code called codons expressed in three-letter codes. Each amino acid has its own assignment of code. The mRNA carries this code to the ribosome which is the site for protein synthesis. The translational RNA or tRNA contains anti-codons to translate the codes in the mRNA into amino acids that link together to form proteins.
Answer:
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
Explanation:
The answer is B. This is called genetic shift. The pups with
advantageous traits are able to survive until the age of reproduction hence able
to pass their genes to the next generation. Few and fewer pups with disadvantageous
traits will get to reproduce hence the allelic frequencies of the shark population
will shift in favour of increased hunting efficiency.
