MRNA is a single-stranded molecule that carries genetic code from DNA in a cell's nucleus to ribosomes, the cell's protein-making machinery.
Answer: The base pairing in the DNA molecule is incorrect.
This is because adenine (A) always pairs with thymine (T) and guanine (G) always pairs with cytosine (C).
Active transport requires energy when moving molecules against a concentration agent. It requires for specific membrane transport proteins. Only a certain type of protein can move a certain type of substance.
The three main types of Active Transport are:
1) Sodium-Potassium Pump
2) Endocytosis

A force is a push or a pull. When one object pushes or pulls another object, you say that the first object is exerting a force on the second object.
