The central dogma of molecular biology is that dna is transcribed into mrna, which is then to protein?

which is then translated to proteins

Explanation:

The central dogma was given by Francis crick which says that the genetic information passes from DNA to mRNA and mRNA to protein but reverse passage of information is not possible.

The process of conversion of DNA into mRNA is called transcription and the process of formation of proteins from mRNA is called translation. The genetic information is present in the sequence of nucleotides that are present in the  DNA.

These nucleotides form the triplet codon in the mRNA and each triplet codon codes for a particular amino acid during translation.

the answer to your question is b

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.
