1. the inheritance of each gene is determined by the units that are passed down 2. an individual will get one unit from each of their parents
3. a trait may not show up on an individual but it can still be passed on to a descendant

Mendel was a Central European monk who published his ideas on genetics in 1866, but did not receive recognition until 1900 after his death. He taught high school mathematics, Greek and physics in the Czech Republic, which was Brno at the time, as well as performing his own genetics research.

Mendel performed his research with plants when studying genetics. Since heredity is the same across species, Mendel's results were able to be applied to both animals and humans. Mendel performed his experiments on common garden pea plants because they were easy to grow in large numbers and he could manipulate their reproduction easily since the pea plants have both male and female reproductive organs.

Mendel was also able to breed pea plants so quickly that he was able to observe inheritance patterns in as many as two generations each year. Mendel observed the principle of segregation and independent assortment and his principles are considered to be "laws" by many scientists today

Answer from: Quest

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.
