Ans.
Protein synthesis involves formation of proteins, during which information present in DNA is used to make polypeptide chains. Hence, amino acid sequence of a polypeptide chain is determined by the sequence that may differ in different species having proteins with same amino acid sequence.
Thus, the molecules that are used to compare different species with proteins having exact same amino acid sequences are DNA molecules.
Protein synthesis includes two steps, transcription and translation. During transcription, DNA gets converted into RNA by RNA polymerase enzyme, while during translation, RNA provides information to make proteins.
In RNA information is present as triplets of nucleotides, known as codon. Each code codes for a specific amino acid. There are a total of 64 codons, while number of protein-forming amino acids is 20. Hence, one amino acid can be coded by more than one codon and this property of codons is known as degeneracy of codons.
Thus, two species may have the same protein even if their DNA molecules are different because of degeneracy of codons.
Clean Air Act (CAA), US Federal law, passed in 1970 and later amended, to prevent air pollution and thereby protect the ozone layer and and promote public health. The clean air act gave the federal environmental protection agency the power it needed to take effective action to fight environmental pollution. Hope this helps シ

The nurse should first select an area to perform the hyphodermoclysis, outside of the elbow is usual but the back of the hand is fine too. Then the nurse must apply a tourniquet 10 cm before the selected area, so it blocks blood circulation. After feeling the vein stand out in the selected area, said area must be cleaned with an antiseptic solution. Then the nurse should introduce the needle connected to the catheter in the outstanding vein, following along the anatomy of the patient against the normal bloodstream direction, so the needle stays almost parallel to the vein while inserted. Finally the nurse must fix the needle to the arm using medical adhesive, and remove the tourniquet.
