Why might it be more useful to classify bacteria and archaea based on their morphology rather than solely on their phylogeny? a. both domains are capable of sharing segments of dna with unrelated organisms which makes genetic classification difficult b. classifying them by shape is more practical since each domain has its own unique and distinctive shapes. c. morphological distinctions are easier to represent on paper than phylogenetic relationships. d. the genetic make-up of both domains is so similar that it makes it difficult to make genetic distinctions between species.

The right answer is A.

There are different types of classifications of bacteria.

The classification of Linnaeus makes it possible to distinguish different levels: the reign, the branch, the family, the genus and the species. That we can associate with the phylogenetic classification.

Another classification, frequently used, corresponds to their reaction in contact with the Gram stain (morpho-tinctorial classification). It is a method to differentiate bacteria based on their staining capacity varying according to the composition of their wall. Thus, the bacteria colored in blue-violet will be said Gram-positive and those in pink Gram-negative.

Finally, they can be classified according to their need for oxygen to survive in aerobic bacteria or anaerobic bacteria.

explanation:

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring 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.

    elongation: in which 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.

    termination: in which 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.
