is the process of creating new living things.

is the phenomenon of living things responding to their environment

1. CELL

2. REPRODUCTION

3. IRRITABILITY

Explanation:

1. All living organisms are composed of CELLS, which according to the cell theory as proposed in the 1800's is the smallest structural and functional unit of life.

2. REPRODUCTION is a characteristics possessed by all living things. It is the process whereby living organisms/things create new living things.

3. IRRITABILITY is another characteristics of living things, which is the process whereby living things respond to changes in their environment called STIMULUS e.g heat, nutrient stress e.t.c.

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.
