The cell cycle of yeast cells grown in the nutrient-poor environment is approximately what percent of the cell cycle of yeast ce
vova2212 [387]

Answer:

Upon nutrient limitation, budding yeast will produce daughter cells less than 20% of the mother cell size. This asymmetric division may select for growth functions that are efficient over a larger range in cell sizes, such as exponential growth. In turn, efficient growth over a large size range lessens the pressure to have precise size control.

Explanation:

In wild-type cells growing in nitrogen-rich medium, the size threshold to enter mitosis is high, and the G1/S size control is cryptic because cell division produces daughter cells with a size greater than the minimum required to initiate S phase. In these conditions, G2 is long and G1 is short. However, the cell size threshold to enter mitosis is greatly reduced when wild-type cells are shifted to medium with a poor nitrogen source, such as minimal medium with proline, isoleucine, or phenylalanine. In these conditions, wild-type cells initiate mitosis at a reduced cell size, generating two daughter cells that are smaller than the critical size threshold required to progress through G1/S

A DNA fragment with the sticky end sequence TGGCA will bind with another DNA fragment with the sticky end sequence _____
klio [65]

Answer:

A DNA fragment with sticky end sequence TGGCA will bind with another DNA fragment with sticky end sequence ACCGT.

Explanation:

When a DNA strand is separated by the restriction endonuclease, it forms two separate single strands. These strands or cuts are known as sticky ends as they are detached from the complementary pairs.

These cuts of DNA are without complementary pairs and when they find suitable base pair, they get attached to it. These sticky ends are allowed to fix with the complementary base pairs during PCR/ polymerase chain reaction.

They are called sticky ends as they are ready to stick with the complementary base pairs of nucleotides.

What is a biological approach to determining when a mother and her conceptus become separate individuals?
pentagon [3]

Answer:

<em>Electroencephalography.</em>

<em></em>

Explanation:

Electroencephalography is used to measure brain activity in terms of electrical activity. It is done by attaching electrodes on the scalp, or sometimes by placing electrodes directly in the brain. Using electroencephalography can help determine when the fetus starts having its own brain activities, which means that it is now a separate entity distinguishable from its mother. Using electroencephalography to see brain waves can give us a deeper insight into the age old complicated issue of when a mother and her conceptus become separate individuals.
