What mRNA sequence would result from the following DNA sequence?
Nezavi [6.7K]

Answer:

UAC CUG AGG AUC

Explanation:

<em>The mRNA sequence from ATG GAC TCC TAG DNA sequence would be </em><em>UAC CUG AGG AUC.</em>

<u>According to Chargaff's base pairing rule, the purine bases always pair with pyrimidine bases. Specifically, Adenine base must pair with Thymine base while Guanine base must pair with Cytosine base. In RNA, Thymine base is replaced with Uracil base.</u>

Hence:

ATG   GAC   TCC   TAG will pair with

UAC   CUG   AGG   AUC

A bowling ball has a weight of 70 Newton’s on earth. What is it’s mass on earth? What’s it mass on the moon?
AnnyKZ [126]

Weight = (mass) x (gravity)

  70 N  =  (mass) x (9.8 m/s²)

Divide each side by  (9.8 m/s²) , and you have

    mass  =  70 N / 9.8 m/s²  =  7.14 kg.
___________________________ 

Mass on the moon:

Mass doesn't change.  It's a number that belongs to the bowling ball,
no matter where the ball goes.  If the mass of the bowling ball is 7.14 kg
anywhere, then it's 7.14 kg everywhere ... on Earth, on the moon, on Mars, rolling around in the trunk of my car, or floating in intergalactic space.

However, WEIGHT depends on the gravity wherever the ball happens to be
at the moment.

The acceleration of gravity on the moon is 1.622 m/s².
So the WEIGHT of the ball on the moon is

        (7.14 kg) x (1.622 m/s²) =  11.58 Newtons

                             That's only about 16% of its weight on Earth.
