m a finished lagging strand. The experiments that led to the discovery of Okazaki fragments gave evidence for which of the following ideas? The lagging strand is characterized by a series of short segments of DNA (Okazaki fragments) that will be joined together to form a finished lagging strand. The experiments that led to the discovery of Okazaki fragments gave evidence for which of the following ideas? DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication. DNA is the genetic material. DNA is a polymer consisting of four monomers: adenine, thymine, guanine, and cytosine. Bacterial replication is fundamentally different from eukaryotic replication.

The correct answer is: DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication

DNA polymerase is an enzyme that synthesizes DNA during the DNA replication by adds nucleotides to the 3’ end of a primer. This means that the new chain is formed in a 5’ → 3’ direction.

Because double-stranded DNA is antiparallel, DNA polymerase moves in opposite directions on the two strands-leading and lagging strand. The leading strand is copied continuously since DNA polymerase is moving towards the replication fork.  The lagging strand is copied discontinuous. DNA polymerase is moving away from the replication fork (and helicase that separates the strands), so it must constantly return to copy newly separated stretches of DNA. So,  the lagging strand is copied as a series of short fragments-Okazaki fragments that are joined together by a combination of DNA pol I and DNA ligase.

You get home from school and grab a bag of potato chips before settling onto the couch to binge watch your newest Netflix series
snow_tiger [21]

Answer:

Explanation:

Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.

While eating the chips, <u>the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution</u>. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. <u>This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis)</u> which causes dehydration in the individual and hence making the individual to be thirsty. <u>The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine </u>(because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).

how does the earth evlove around the sun while the moon evlolves around the earth with out those two planets colliding
ICE Princess25 [194]

Answer:

This is a rather complicated thing to explain so I'll try my best. To put it in simple term the sun has whats called a SOI (sphere of infleunce) and anything inside of this is effected by the gravity of that planet or sun in this case. The earth is inside of this sphere of influence. The earth has a constant velocity that is making it move away from the sun but since it's in the suns SOI the path in which the earth moves is changed in a way that causes it to spin around the sun. The same thing is happening with the moon. I'm not 100% sure on this but I think the reason the moon does not just fly away towards the sun is because it is closer to earth and is more effected by earths SOI. Hope this cleared things up for you.

Opening K or Cl- channels in a postsynaptic membrane would produce an inhibitory postsynaptic potential (IPSP). Opening K or Cl-
Gennadij [26K]

Answer:

True

Explanation:

In inhibitory postsynaptic potentials, the opening of chlorine and potassium channels generally occurs so that chlorine enters, with a negative charge, and potassium leaves, with a positive charge. The synergistic effect of this ionic flow is the hyperpolarization of the cell, making it difficult for an action potential to occur.
