The method that holds the two strands of the dna helix together is known as? a) enzyme attraction b) base pairing c) codons d) anticodons

autosomal

explanation:

is a term used in genetic genealogy to describe dna which is inherited from the autosomal chromosomes

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
