Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e
cricket20 [7]

Answer:

  • The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
  • According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
  • After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.

Which describes a complex carbohydrate cellulose
miv72 [106K]
Like starch, cellulose is a complex carbohydrate made up of many molecules of glucose linked together. But unlike starch, plants do not use cellulose to store energy. Instead, plants use cellulose as a structural molecule. It forms the cell wall that gives plant cells shape and support.

Valine is an amino acid used to make proteins. It is an essential amino acid meaning the body cannot synthesize it and thus, it
valentinak56 [21]

<u>Answer:</u>

<em>The correct option is Option C i.e. its hydrophobic. </em>

<em></em>

<u>Explanation:</u>

The side chain of valine is isopropyl group. It is a hydrocarbon side chain. Isopropane is a hydrophobic compound. So as it joins with the amino acid skeleton as a variable group, it makes the whole amino acid hydrophobic.

Its hydrophobic nature is well evident from the disease of sickle cell anaemia. The replacement of hydrophilic glutamate by hydrophobic valine makes the interaction of haemoglobin by changing other components.
