After the mRNA is formed, what happens?
alexdok [17]

Answer:

The correct answer is - B. It moves out of the nucleus and into the cytoplasm.

Explanation:

mRNA formation is known as transcription which is the first process of protein synthesis in which mRNA is formed from DNA sequence with help of RNA polymerase enzyme.

After forming the mRNA sequence this mRNA moves out of the nucleus and reaches the cytoplasm where it performs the second process called translation with help of tRNA and ribosome to produce an amino acid chain.

Which discovery supports the hypothesis that evolution of the lactase-persistence trait was driven by the use of milk in pastora
V125BC [204]

The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots

lactase persistence:

Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.

The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.

Explain why plants along the road often die after the road is sprayed with a salt solution to melt ice
vovangra [49]

Explanation:

The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.
