During DNA replication, which chemical bonds break apart?

Biology
1 answer:
Grace [21]3 years ago
3 0

Answer:

During DNA replication, the hydrogen bonds must be broken between the complementary nitrogenous bases in the DNA double helix. Once this is accomplished, either side of the DNA molecule can act as a template to produce another double stranded DNA molecule.

What is the difference between a pressurized water reactor and a boiling water reactor?
lesya [120]

Answer:

Its c

A pressurized water reactor does not boil the water!

Explanation:

  • There are different type of nuclear power plants, that are used to generate electricity other than the water ,wind and solar electricity generation.
  • The nuclear power plants use uranium as fuel that heat the water and the steam generated runs the turbine
  • The most common type of nuclear power reactors are :-

The pressurized water reactor

  • It heats boils the water to ane extreme temprature but it doesnt boil it that water due to the great amount of pressure it is under  

The boiling water reactor

  • the nuclear fission reaction of uranium generates great amount of enegery that is absorbed by the water and it starts to boil , the steam generated runs the turbines

Suggest a means by which you could separate mrna from the other types of rna in a eukaryotic cell
jok3333 [9.3K]

A method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

<h3>What do you mean by mRNA?</h3>

mRNA may be defined as a molecule in cells that holds codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm.

The mRNA can be easily isolated from other types of RNA by the most reliable and convincing method of oligo (dT) chromatography which is the magnetic separation method that bounds oligo (dT) molecules on the surface of paramagnetic beads.

Therefore, a method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

<h2>DNA </h2>

Explanation:    

1) Experiment done by Griffith:

  • Griffith used two related strains of bacteria, known as R and S
  • R bacteria were nonvirulent, meaning that they did not cause sickness when injected into a mouse whereas mice injected with live S bacteria developed pneumonia and died
  • Griffith tried injecting mice with heat-killed S bacteria (that is, S bacteria that had been heated to high temperatures, causing the cells to die), the heat-killed S bacteria did not cause disease in mice
  • When harmless R bacteria were combined with harmless heat-killed S bacteria and injected into a mouse, not only did the mouse developed disease and died, but when Griffith took a blood sample from the dead mouse, he found that it contained living S bacteria
  • Griffith concluded that the R-strain bacteria must have taken up what he called a transforming principle from the heat-killed S bacteria, which allowed them to transform into smooth-coated bacteria and become virulent

2) Experiment done by Avery:

  • Avery, McCarty and MacLeod set out to identify Griffith's transforming principle
  • They began with large cultures of heat-killed S cells and, through a long series of biochemical steps progressively purified the transforming principle by washing away, separating out, or enzymatically destroying the other cellular components
  • These results all pointed to DNA as the likely transforming principle but Avery was cautious in interpreting his results
  • He realized that it was still possible that some contaminating substance present in small amounts, not DNA, was the actual transforming principle

3) Experiment done by Hershey and Chase:

  • Hershey and Chase studied bacteriophage, or viruses that attack bacteria
  • The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA
  • Hershey and Chase concluded that DNA, not protein, was injected into host cells and made up the genetic material of the phage
