Alternative RNA processing generates different mRNAs that can direct the synthesis of different polypeptides. Alternative RNA processing generates different mRNAs that can direct the synthesis of different polypeptides. True False

True

Explanation:

RNA processing or splicing refers to the process of removing the non-coding sequences (introns) from the pre-mRNA and the coding sequences  (exons) are then joined to undergo translation.

But an mRNA can undergo more than one splicing and can form multiple types of mRNA for translation through a process called the alternative splicing.

The alternative splicing removes the introns between the exons and can form more than one combination of exons and  thus different proteins after the translation.

Thus, true is correct.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
