if a number cube is tossed once which of these is the most likely outcome one, 3, a number greater than 1, or number less than 3
Naddik [55]
A greater more than 3 because in a cube there are 6 numbers  1,2,3,4,5,6
Then it is not equal to have 1 greater than a tree has four numbers and less than three has 2. So more likely, Greater than three.

Describe the steps in transcription that require complementary base pairing.
nalin [4]

Answer:

Explanation:

Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.

During transcription, the code present in DNA gets transcribed into the code in mRNA.  (messenger RNA)

RNA even though is a single stranded shows base pairing.

The pre-mRNA gets created from the DNA.

DNA has two strands, one of these strands acts as coding and another non coding strand.

The DNA shows base pairing with AGTC.   [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]

Whereas mRNA base pairing with AGUC.  [ U- Uracil ]

Here in mRNA, instead of thymine, uracil gets paired.

According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.

The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.

The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
