How are the nature of genes expressed

Biology

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.
At any given time, the amount of a particular protein in a cell reflects the balance between that protein's synthetic and degradative biochemical pathways. On the synthetic side of this balance, recall that protein production starts at transcription (DNA to RNA) and continues with translation (RNA to protein). Thus, control of these processes plays a critical role in determining what proteins are present in a cell and in what amounts. In addition, the way in which a cell processes its RNA transcripts and newly made proteins also greatly influences protein levels.

Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.

The second edition of bergey's manual of systemic bacteriology is largely based on ________ classification.
Lady_Fox [76]

The second edition of bergey's manual of systemic bacteriology is largely based on  of prokaryotic classification.

<h3>What does bergey's manual of systemic bacteriology talk about?</h3>

Since publication of the first edition of Bergey's Manual of Systematic Bacteriology, it has become recognized throughout the world as the principal monographic work in the field of prokaryotic biology. Like a dictionary to a writer, the Manual is usually the first reference that a microbiologist consults when questions arise regarding the characteristics of an unfamiliar species or an unknown strain that bears some similarity to a more familiar one.

While the first edition has served the community well for many years, it has become outdated. As a result, the editorial board of Bergey's Manual Trust, in collaboration with more than 500 of the world's leading authorities in prokaryotic systematics, is in the process of revising Bergey's Manual of Systematic Bacteriology so that it reflects current thinking and advances in the field.

With this information, we can conclude that Phylogenetic classification is now broadly accepted as the preferred method of representing taxonomic relationships among prokaryotes and eukaryotes alike.

Please help!!! I don't know how to tell if they self pollinate or not.
-BARSIC- [3]

Answer:

The first flower can self pollinate because it is open, so the wind will pollinate it.

Explanation: Flower b will not self pollinate because it is not open, so it will not pollinate until a bird or moose or any other animal comes and eats it, then poops it out, so the seeds get planted.
