Answer:
Progesterone is one of the female sex hormones which performs important function during menstrual cycle, pregnancy and embryo development.
During follicular phase, it helps in the ovulation while during luteal phase it plays an important function of preparing the endometrium lining of the uterus. In addition, it also inhibits or decreases the production of FSH and LH during this phase with the help of negative feedback mechanism.
Progesterone gives negative feedback to hypothalamus and anterior pituitary which decreases or inhibits the secretion of FSH and LH. It is important as it prevents the ovulation of second egg prior to fertilization.
A eukaryotic cell is much more complex than a prokaryotic cell. Eukaryotic cells usually make up more complex organisms and have organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, a nucleus, and lysosomes. A prokaryotic cell only has circular chromosomes and is much smaller than a eukaryotic cell. Most single celled organisms are prokaryotes.

Answer:
3 The mRNA was not bound to by a ribosome 4 tRNA: anticodon matching 5 switching from normal nucleotide for an abnormal one .
Explanation:
3 If the mRNA is not bound to the ribosome then this do not prevent the mRNA from being transported to the Endplasmic reticulum in the cytoplasm.This because binding of ribosome to the mRNA is essential after the mRNA has reached the cytoplasm to initiate the process of protein synthesis.
4 tRNA contains Anticodons that interact with the codon present in the mRNA to bring an amino acid specific for that codon to the A site of ribosome.
5 Mutation at the 3" nucleotide reading frame switch a normal nucleotide for an abnormal one.
