The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well
Rainbow [258]

Answer:

PFK: cytoplasm

insulin: ER--> Golgi--> outside cell

Explanation:

As described in the question, the enzyme phosphofructokinase (PFK) functions is a cells cytoplasm. Enzymes are proteins and proteins are made in the ribosomes of a cell. As ribosomes are present in the cytoplasm, hence PFK once made in the ribosomes will be released into the cytoplasm.

As for insulin, it will be made in the ribosomes. from there, it will move to the Endoplasmic Reticulum for packaging. Then to the Golgi complex for modifications and further packaging. Only after these stages, it will be ready to move out from where it is produces to areas where it has to be used.

In Kerr and Wright's experiment with 96 fruit-fly populations, only 4 males and 4 females bred in each generation. After 16 gene
Svetradugi [14.3K]

Answer:

2.Less than 73% of the populations would have only one allele present.

Explanation:

The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.

Using a larger breeding population would not be expected to alter the outcome of the experiment.
