Which two levels of classification are represented in an organism's scientific name? class and kingdom domain and phylum genus and species family and order

Genus and species.

Explanation:

The system of the biological classification is important to classify the organisms into different group. Linnaeus is known as the father of biological classification.

The naming of the species that comprises two levels are known as known as biological nomenclature. The first name of the organism represents the genus and the second name represent the species to which the organisms belong.

Thus, the answer is option (3).

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.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
