Which of these engulf bacteria and break them down? a lymphocytes b phagocytes c t-cells b b-cells

B. phagocytes

A phagocyte is a specialized type of cell that is capable of ingesting as well as digesting the foreign particles entering the body of the organism which are potent enough to cause disease. These are bacteria, dust, chemical molecules and others. It is a special type of cell that extends the cytoplasm and engulfs the foreign agent completely to ingest and digest it by using enzymes and forms a vacuole to dispose it off from the body.

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.
