Aplant that has genes for tallness may not be tall if the plant a: has no opportunity to be cross-pollinated b: does not get the proper nutrition c: has red flowers

The correct answer is option B

The height of the plant depends o the gene present in the plant and secondly it depends on the environmental conditions in which the plant is grown. Though the plant is having the gene that is responsible for its tallness and the plant is not getting enough nutrition for its growth, then it will not grow tall.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

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.
