Select the true statement(s) about microbes. a. some microbes are visible to the naked eye. b. the domain archaea does not include microbes. c. most microbes are pathogens. d. viruses and prions are considered microbes.

option A and D.

Some microbes are visible to the naked eye. Virus and prions are considered as microbes.

Explanation:

Microbes or microorganisms are small living creatures that are either microscopic (not visible with the naked eye or seen with microscope) or visible to the naked eye when they form colony that are found everywhere. Most microbes are beneficial to man in that they aid digestion of food and decomposition of organic material which serve as fertility to soil. Examples of microbes are Bacteria, fungi, viruses, prions e.t.c.

Though some microbes are pathogens I.e they cause diseases but many microbes are beneficial.

youre right there are

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.
