Use the double-stranded dna molecule below to answer the following questions. the first pair of nucleotides (bolded) contains the start point of transcription.
5'-atgtcaggtacgccacat-3'

3'-tacagtccatgcggtgta-5

which of the following is the correct mrna produced from the transcription of this dna molecule?

1. 3'-uacaguccaugaggugua-5'
2. 5'-augucagguacgccacau-3'
3. 3'-uacaguccaugcgguaca-5'
4. 5'-auguggaguaccugacau-3'

5'-AUGUCAGGUACGCCACAU-3'

Explanation:

The correct answer is B. because DNA is read in 3′ to 5′ while the mRNA produced in 5′ to 3′.

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.
