What is the purpose of transcription?A. To produce a nucleic acid sequence from an amino acid sequenceB. To form RNA molecules from DNAC. To copy the nucleotides in DNAD. To link amino acids together to form strands of protein

B.To form RNA molecules from DNA

Explanation: Transcription is a process of copying the genetic messages contained in a DNA into an RNA molecule. The purpose of this is to produce different RNA molecules needed for bodily functions. Basically three types of different RNAs can be produced from DNAs: messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA. Messenger RNA contains the genetic information for making proteins, transfer RNA fetches and attaches the correct amino acid during protein synthesis.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
