1. Recently, a human lung (a respiratory organ) was produced by using a patient's own stem cells. The benefit of using the patient's cells to produce a lung instead of receiving one from a donor is that 1) there will be more enzymes produced to help maintain homeostasis in the trachea 2) there will be an increase in the quantity of antibodies that the patient produces in response to the new trachea 3) there is less of a chance that the patient's immune system will attack the trachea 4) there will be a greater response to any infectious agent that may enter the body
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
