Which of the following causes the characteristic palisade arrangement of corynebacterium diphtheriae cells when viewed on a slide? a) lophotrichous flagella
b) snapping division
c) endospore formation
d) the large glycocalyx

snapping division

Explanation:

Snapping division a form of binary fission is a type of reproduction in prokaryotes that results in a palisade arrangement of cells. Corynebacterium diphtheriae cells reproduce by snapping division. In snapping division of bacteria only the inner layer of the cell wall forms. This puts tension on the remaining cell wall causing it to "snap" or tear. The two cells still remain attached by the remaining cell wall called a hinge.

answer; a male inherits only one allele of the x-linked gene controlling hair color;

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.
