When creating DNA, DNA polymerase can add free nucleotides only to the 3' end of the newly forming strand. This results in elongation of the newly forming strand in a 5'-3' direction.hen creating DNA, DNA polymerase can add free nucleotides only to the 3' end of the newly forming strand.

A part-time contract is a form of employment that carries fewer hours per week than a full-time job. They work in shifts. The shifts are often rotational. Workers are considered to be part-time if they commonly work fewer than 30 hours per week. According to the International Labour Organization, the number of part-time workers has increased from one-fourth to a half in the past 20 years in most developed countries, excluding the United States.
For example, most employers define full-time as an employee who works anywhere from 32 to 40 or more hours per week. However, the Affordable Care Act (ACA) defines full-time as working, on average, at least 30 hours per week. Under the ACA, a part-time employee is any employee who works fewer than 30 hours per week on average.
