You should use a Punnett Square for this question
The Punnett square predicts the offspring of two parents (two alleles). In this case you have brown eyes (Bb) and blue eyes (bb)
In the four boxes you should have Bb, Bb, bb and bb (50% chance of offspring with blue eyes and 50% chance of offspring with brown eyes).
The genotypes ratio will be 2Bb:2bb
And the phenotypic ratio will be 2 Brown : 2 Blue

If you are driving down the road, how do you know that the car is moving (think about your reference point)?
NISA [10]
If your car is changing speed by accelerating or decelerating, or changing directions by turning or hitting a bump, your body can sense these accelerations. You might be pressed against the back of your seat while speeding up or against the car door as you turn for example. If you are cruising at a constant speed, with no changes in speed or direction, you wouldn't be able to feel it. You would need to use your other senses. You could see the scenery going by through the windows, with closer objects moving by more quickly than objects in the distance. You could also hear sounds like the wind rushing by and the hum of the tires rolling on the highway.

Arrange the events taking place during transcription in order: i) The pre-RNA undergoes processing ii) RNA polymerase moves down
Anastasy [175]

Answer:

RNA polymerase binds to the promoter

Polymerase initiates RNA synthesis at the start point on the template strand

RNA polymerase moves downstream unwinding the DNA

RNA transcript is released and polymerase detaches from the DNA

The pre-RNA undergoes processing

Explanation:

The promoter is the specific DNA sequence that serves as a binding site for RNA polymerase. The enzyme RNA polymerase recognizes the promoter sequence and binds to it to begin the process of RNA synthesis. The process of RNA synthesis begins at the start site where the process of the unwinding of DNA duplex is initiated.

The unwinding separates the two DNA strands at the start site where RNA polymerase begins the process of synthesis of the new RNA strand. The newly formed RNA strand and RNA polymerase are released from the template strand after the termination of the process.

In eukaryotes, the primary RNA transcript undergoes the process of splicing of introns, the addition of poly-A tails and 5' cap which in turn transform it into the mature mRNA.
