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 sports car and a minivan run out of gas and are pushed to the side of the road. Which is easier to push, and why?
astraxan [27]

Answer:

The correct option is;

The sports car, because it has less mass and therefore less inertia

Explanation:

Newton's first law of motion states that an object will continue in its state of rest or uniform motion in a straight line unless acted on by a force. The property exhibited by the object is known as inertia

Newton's second law states that force is directly proportional to the rate of change of momentum produced

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force. The resultant force is equal to the rate of change of momentum.

Therefore, we have;

F = m·dv/dt = m×a

Given that the force required to move an object is directly proportional to its mass therefore, the inertia or the object resistance that requires a force to bring change is directly proportional to the mass of the object.

The mass of a sports car being considered lesser than the mass of the minivan will require less force to push and therefore has less inertia.

When placed 1.18 m apart, the force each exerts on the other is 11.2 N and is repulsive. What is the charge on each
aleksandr82 [10.1K]

Answer:

q=41.62\ \mu C

Explanation:

Given that,

Force between two objects, F = 11.2 N

Distance between objects, d = 1.18 m

We need to find the charge on each objects. The force between charges is as follows :

F=\dfrac{kq^2}{r^2}\\\\q=\sqrt{\dfrac{Fr^2}{k}} \\\\q=\sqrt{\dfrac{11.2\times (1.18)^2}{9\times 10^9}} \\\\q=41.62\ \mu C

So, the charge on each sphere is 41.62\ \mu C.
