Explanation:
A progestrone is a hormone which inhibits the contraction of the uterine muscles and also develops and maintains the lining of the uterus so as to support the development of the fetus till the period of delivery or child birth.
Amniocentesis, chorionic villus sampling, percutaneous umbilical blood sampling are the procedures of which the nurse will ensure that the client's signed informed consent has been given and is in the client's record.
Amniocentesis is a procedure in which amniotic fluid is removed from the uterus for testing or treatment. This fluid surrounds and protects the baby during pregnancy and contains various proteins and fetal cells.

Answer: A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalentstructure of the entire molecule.
