What is the correct order of anatomical structures internal to external? select one: a. oviduct, ovary, cervix, uterus, vagina b. oviduct, cervix, ovary, uterus, vagina c. ovary, cervix, oviduct, uterus, vagina d. ovary, uterus, cervix, oviduct, vagina e. ovary, oviduct, cervix, uterus, vagina f. none of the above?

Answer;

f. none of the above

Explanation;

The correct order would have been; Ovary, oviduct, uterus, cervix , vagina.

The female reproductive anatomy comprises of the internal and external parts. All these parts combine their functions to give life.

-This system has structures with specialized functions (ovaries, oviduct, uterus, and vagina). For example, the ovaries produce the ova, the oviduct provides a surface for fertilization, the uterus nurtures the fetus and the vagina acts as an entry point of the male sperm, the exit of menstrual flow if fertilization does not take place and the as a birth canal.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
