Answer:
Semi-conservative DNA replication:
The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.
Conservative model of DNA replication:
The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.
The semi-conservative mode of DNA replication is found in the living organism.
Answer:
Explanation:
The earth turns on its axis every day; it orbits the sun, just like all the other planets in our Solar System. When viewed from space, it turns counter-clockwise.
Because it rotates around the earth at the exact same speed as it rotates around its own axis, so that the same side of the moon is constantly facing the surface of the earth.
Tilt of the earth on its axis is responsible for season formation. The amount of sunlight obtained by various regions on earth surface is regulated by tilt. The places of earth that are facing the Sun and get direct sunlight experiences summers while the others which are facing away from the Sun experience winter season.
Answer:
When directed mutagenesis which is also called reverse genetics is used, only a single mutation per genome is introduced. In contrast, the number of mutations per genome introduced by random mutagenesis is usually difficult to control. It is likely that the strain you obtained with a mutation in gene X after random mutagenesis contained an additional mutation or perhaps multiple mutations which ultimately was/were responsible for loss of virulence in your favorite pathogen.
It is kind of difficult for me even, but I know that neutral objects<span> have an even amount of opposite </span>charges<span>. When </span>brought near a charged object<span> the </span>neutral's<span> protons will lean toward excess electrons on the </span>charged<span> one. A positively </span>charged object<span> will attract the neutrals electrons to move toward it. I hope that kind of helped. Sorry if I couldn't give a direct answer! Its kind of hard for me too and I'm an A+ student in bio</span>
The correct sequence is; Glycolysis-pyruvate-acetyl CoA-krebs cycle-electron transport chain.
Glycolysis is a sequence of reactions for the breakdown of glucose to two molecules of pyruvic acid under aerobic conditions, Krebs cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the energy carriers, while electron transport chain involves a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions and couples this transfer with the transfer of protons across a membrane.
