Describe how the bacterial cloned cells on your LB/amp plate differ from the cells on your LB/amp/ara plate. How would you desig

n an experiment to show that both plates of cloned cells behave similarly and do contain the same DNA?

I’m not too sure about showing similar behaviour but as for containing the same DNA, you could probably extract the DNA and conduct DNA sequencing

A biochemist isolates and purifies various molecules needed for DNA replication. When she adds these molecules to DNA, replicati
olga55 [171]

Answer:

DNA ligase

Explanation:

<em>The biochemist must have left out DNA ligase enzyme.</em>

<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>

The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.

Hence, the missing component is the DNA ligase.

Gabriel has developed diarrhea as a result of taking an antacid. what does the antacid likely contain?
lora16 [44]

If Gabriel developed diarrhea as a result of taking an antacid, he's been taking an antacid that contains magnesium.

Magnesium will act as a laxative.

A researcher is studying different mutations in yeast. He isolates one yeast strain that fails to properly form replisomes. When
olga nikolaevna [1]

Answer:

The correct answer is "both Cdc6 and Cdt1"

Explanation:

The replisome is a complex molecular system that allows for the replication of DNA in yeast. There are multiple genes that participate in the replisome function, however if a researcher finds out that a yeast strain fails to properly form replisomes it is very likely that the genes that might be mutated are both Cdc6 and Cdt1. Cdc6 and ORC are the genes that send the signal to the yeast to start the replisome formation, and Cdt1 is a DNA replication factor that if it is mutated it could cause that yeast is not able to form the replisome.

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

Why have fossil's of some extinct organisms have been found and others haven't?
xz_007 [3.2K]
Fossils only form if certain qualifications are met, and some organisms cannot meet them, so they just cease to exist, not a single sign of them. This could happen if they were organisms that decayed completely. Fossilization can include freezing, drying, and encasement, usually in tar or resin.
