what is the difference between the closed conformation and open conformation of chromatin packing? biology
Oduvanchick [21]

The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.

  • The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
  • With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
  • All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
  • While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.

what genetic information can be obtained from a punnett square? What genetic information cannot be determined from a punnett squ
aleksley [76]
A punnet square determines all of the ways in which alleles can combine. It may be used to predict ratios of offspring genotypes and phenotypes. However, Punnet squares cannot determine actual outcomes. They can only predict the possibility for things to happen. The exception to this takes place when the cross occurs with two homozygous dominant or recessive genes and the resulting offspring is either be 100% homozygous dominant or recessive.

and in whole milk the percentage of milk fat is 3.25%</span>

To get the percentage of milk fat, divide the grams of fat present in milk by the total weight of milk and then multiply by 100.

<span>There are many types of milk, like skimmed milk, low fat milk, partly skimmed, raw milk, whole milk etc. in all these types the percentage of milk fat is different.</span>
