First hematoma appear, then callus is formed, then ossification occure, and last thing remodelling of the bone.
<span>The two ways atoms are formed is by elements, combine to form chemical compounds that are often divided into two categories. Metals often react with nonmetals to form ionic compounds. These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules</span>
Answer:
D. Start codon: AUG; stop codon: UAA; protein: Met-Ala-Leu-stop
Explanation:
- Start codon is the first codon in mRNA which is translated to an amino acid. AUG is the most common start codon and corresponds to methionine in eukaryotes and modified methionine in bacteria.
- Stop codon ends the translation process. There is no corresponding amino acid to it and the newly formed mRNA exits the translation machinery. There are three types of stop codons: UAA, UGA and UAG.
- GCA codon codes for Alanine and CUU codon codes for Leucine.
- Hence in the given sequence AUG is the start codon, UAA is the stop codon and the resulting amino acid sequence is Met-Ala-Leu-stop.
The Human Immunodeficiency Virus (HIV) has been discovered to be the cause of AIDS.
AIDS or Acquired Immunodeficiency Syndrome is caused by the Human Immunodeficiency Virus (HIV). HIV is a retrovirus which contains RNA as the genetic material.
HIV infection can be transmitted through:-
- sexual contact with an infected individual,
- transfusion of contaminated blood samples,
- sharing infected needles e.g. in the case of drug addicts who take the drug intravenously,
- infected pregnant woman to the fetus through placenta.
AIDS adversely affects the immune system of an infected individual. ELISA or enzyme linked immunosorbent assay test is used largely for diagnosing AIDS.
