Capacitive loads have a leading power factor. Current leads voltage when there is capacitive reactance. (The opposite is inductive, which is lagging.)
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
Not in general replication as the leading strand is replicated straight away. The lagging strand is replicated in pieces that need ligase to affix them, one to the other. However, in a replication bubble, when a lagging strand runs into a leading strand, and later the primers are replaced, ligase is still needed. Therefore, technically, the leading strand does need the ligase once.
Lagging strand synthesis would be incomplete; leading strand synthesis would be unaffected.

The terms, 'leading' and 'lagging' refer to what the load current is doing, relative to the supply voltage (Phase difference) -never the other way around. If the current is leading the voltage, then the power factor is 'leading'; if the current is lagging the voltage, then the power factor is 'lagging'.
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
By definition, the terms 'leading' and 'lagging' refer to what the load current is doing with respect to the supply voltage. So, for a 'lagging power factor', it is the current that is lagging.
A lagging power factor is caused by inductive reactance, which is composed of resistance and inductance -- and the resistance component lowers the supply volts. A leading power factor provides capacitive reactance that actually helps improve source voltage -- this helps motor loads run cooler.
Capacitive loads have a leading power factor. Current leads voltage when there is capacitive reactance. (The opposite is inductive, which is lagging.)
underdampedAnswerA lagging power factor describes a situation in which the load current is lagging the supply voltage. This describes an inductive load, such as a motor, etc.
Because capacitor withdraw leading current from source and net resultant become less lagging.
The lagging strand.
Power factor is the cosine of the angle by which the current leads or lags the voltage in an a.c. circuit. It can also be defined as the ratio between a load's true power (expressed in watts) and its apparent power (expessed in volt amperes).Power factor is designated as 'leading' or 'lagging' which is determined by whether the current is leading or lagging the supply voltage. Leading currents are associated with resistive-capacitive circuits, whereas lagging current are associated with resistive-inductive circuits.
Power Factor is the ratio of true vs apparent power, and comes into play with a reactive (inductive or capacitive) load. A purely resistive load, such as a light bulb or toaster, will have a power factor of 1 because the current is in phase with the voltage. An inductive load, however, such as a motor, will have a power factor less than 1 because the current lags the voltage. You could also have a capacitive load, with a power factor less than 1, but in this case the current leads the voltage.AnswerThe terms, 'leading' and 'lagging' refer to whether a circuit's load current is leading or lagging the supply voltage. Current will 'lead' in resistive-capacitive (R-C) circuits, and 'lag' in resistive-inductive (R-L) circuits. So, a 'leading power factor' indicates a leading current, and applies to R-C circuits, while a 'lagging power factor' indicates a lagging current, and applies to R-L circuits.
A leading power factor means that the current is leading the voltage. That means that in the AC cycle (50 or 60 Hz) the current reaches its peak before the voltage. The amount of phase-lead can be up to 90 degrees which means one quarter cycle, or 5 milliseconds in a 50 Hz system.
Applying a negative or positive sign to power factor is an obsolete method of describing whether it is 'leading' or 'lagging'. We no longer do this. These days, a 'leading power factor' indicates that the load is capacitive and the load current is leading the supply voltage, and a 'lagging power factor' indicates that the load is inductive, and the load current is lagging the supply voltage. Having said that, a 'negative' power factor is also the mathematical consequence of 'negative power' -i.e. the direction of power when it is fed from the load back to the supply (e.g. when the grid feeds energy into a generator, causing it to 'motor'). In this case, the power factor isn't really negative, but simply appears to be so.
