The technique of lowering the coverslip at an angle is used to) a. make organelles b. reduce the formation of air bubbles c. make the specimen transparent d. reduce the size of the specimen

The technique of lowering the cover slip at an angle is used to;

B. Reduce the formation of air bubbles

It is essential that the technique of lowering the cover slip at an angle is used to put a cover slip at that angle and to lower it onto the specimen to avoid creating air bubbles which would interfere with the view.

explanation:

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.
