<span>B is the correct answer. The beginning of DNA replication occurs with the unwinding of the DNA helix by a special enzyme. The two strands that form the helix then create a replication fork. The two strands are then oriented differently, one becoming the 'leading strand' and one the 'lagging strand'. </span>
Answer:
Industrialization and revolution are the same because they bring a positive sudden change into the society.
Explanation:
A sudden change in the society meant to be a major result of revolution. This also goes along with industrialization, because the more there are creation of industries, the more the will be increase in employment rate and production of foods, which will eventually raise the standard of living of the people in the society.
Answer:
Advantage of gene expression in prokaryotes is it occurs faster than in eukaryotes because transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Whereas disadvantage of gene expression in prokaryotes is that there is no post translational modification and low expression of genes.
Explanation:
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. whereas in eukaryotes, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm.
Prokaryotic Cells = do not have a nucleus; generally smaller and simpler that Eukaryotic cells.
-Smaller
-does NOT have a Nucleus
-translates to ‘no Nucleus’ OR ‘no true Nucleus’
-simpler
-they don't have all of their genetic material bound in a nucleus, which is why they are simpler forms of life.
-Prokaryotic cells do have genetic information but it is just stored differently
Ex: Bacteria and Single-Celled organisms
Eukaryotic Cells = Contains a Nucleus and are usually larger and more complex than a Prokaryotic cell
-Bigger
-DOES have a Nucleus
-More Complex
-Specialized to do certain things
Ex: All the Cells in a Human’s body. Skin cells, Red Blood cells
Explanation:
I think that if you use different methods that result in the same outcome <em>you </em><em>will </em><em>have </em><em>more </em><em>chances </em><em>of </em><em>getting </em><em>the </em><em>required </em><em>res</em><em>u</em><em>l</em><em>t</em><em>.</em><em> </em><em>This </em><em>is </em><em>because </em><em>you </em><em>don't </em><em>know </em><em>whether </em><em>one</em><em> </em><em>of </em><em>your </em><em>methods</em><em> </em><em>might </em><em>work </em><em>or </em><em>not</em><em>, </em><em>so</em><em> </em><em>having </em><em>many </em><em>of </em><em>them </em><em>help </em><em>you. </em>
Not sure if I'm correct or not but I hope this helps
