DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.

Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.

The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.

The points where DNA is currently unwinding are called replication forks.

If you flip a penny 99 times and each time it came up heads then the chance of the penny coming up heads is ___

Helga [31]

The chances of heads as a result when flipping a penny will always be 50%. Although heads came up 99 times in a row, the events that occurred before will not affect the probability of the current event in terms of a coin flip.

There are 1 out of 2 chances of it occurring or 1/2. Divide that and multiply it by 100% to get the probability in percent. So the answer will be 50%.

The answer is B.
