Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).
Explanation:
During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA is then used as template to create a protein by a process called translation.
Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.
The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.
In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
Pure culture can be prepared from a mixture of cultures by using the streak plate method. This enables the bacterial cells to be diluted to obtain a pure culture after many-folds dilution.
Pure culture is the one in which only one species, strain or clone of bacteria are grown. The pure culture enables to scientists to study in detail about its anatomy, lifestyle and potential uses or harms, without the interference of any other microbe.
Streak-plate method is the most commonly used technique in microbiology labs to isolate a single type of bacteria. It is performed by creating the smears of bacteria in zig-zag motion to dilute its concentration.

Answer:
The answer is A.
Explanation:
Phylogenetic trees are only concerned with hard data (time points of when species evolve) and not soft data like how great a species is.
Vertebrae/Backbones I think.
