Answer:
Here is the complete question
The initiation of transcription requires melting of the DNA double helix, i.e. separating hydrogen-bonded base pairs, immediately upstream of the +1 site. In E. coli this melting is accomplished by ___________.
-DNA helicase unwinding the double helix around the +1 site.
-DnaA:ATP complexes binding to and twisting the double helix at the +1 site.
-RNA polymerase obtaining the energy to cause separation of strands from ATP hydrolysis.
-binding of the DNA complexes to the double helix at the +1 site and twisting of the double helix.
-bases at the promoter region flipping outward from the double helix into pockets on the polymerase.
And the answer is.....
bases at the promoter region flipping outward from the double helix into pockets on the polymerase.
Answer:
Not necessarily
Explanation:
There are animals in which vision and audition are more specialized than in humans, while in other species this relation fails. For example, in predatory birds, the vision clarity surpassing human eyesight, since this sense is required for effective prey capture. Conversely, in the European mole (<em>Talpa europaea</em>), which is a mammal that lives mostly underground, the vision is seriously short-sighted. These are clear examples that "the function makes the organ", ie., phenotypic features such as vision and audition are selected in the course of evolution depending on the fitness that they confer to the species in particular environmental conditions.
This phenomenon is referred as Codominance. Codominance is termed as, the distinct expression of both alleles of a gene.
Cell is the structural and functional unit of life. All living organisms are made up of cells. The size of any living cell is limited. Limited cell size has many advantages.
Answer: Analogy to explain why cell size is limited is SMALLER THE SIZE OF A CELL LARGER WILL BE THE SURFACE AREA TO VOLUME RATIO.
Answer:
Summer
Explanation:
The Northern hemisphere is facing the sun completely, so summer is right.
I hope this right!
