The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
Answer;
-Flagellum (flagella; plural)
Explanation;
-Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea.
-A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi.
-The primary role of the flagellum is locomotion, but it also often has function as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. Flagella are organelles defined by function rather than structure. Flagella vary greatly. Both prokaryotic and eukaryotic flagella can be used for swimming but they differ greatly in protein composition, structure, and mechanism of propulsion.
Answer:
Taj Mahal is slowly losing its white color because of pollutants from vehicles and industries around it. It is a result of chemical weathering. Polluted air contains a large amount of nitrogen and sulfur oxide released from the industries in the area.
These chemical comes down with the rain and called acid rain. This acid rain reacts with the marble which is made up of calcium carbonate thereby turning the Taj Mahal yellow.
These environmental pollution cause the oxidation of marble constituents from which Taj Mahal is made up of and are responsible for the chemical weathering of Taj Mahal.
Answer:
The cells produced during mitosis are identical but cells produced in meiosis are different.
Explanation:
This is because in mitosis, there is no crossing over, but crossing over occur in meiosis. During crossing over, there is swapping of the genetic material.
