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.
Generally speaking, most employers treat a regular work schedule of 35 hours or more as full time. But many employers say anything less than a 40-hour regular schedule is part time. Therefore, the employer could choose to make 39 hours per week part time. Many employers opt to give prorated benefits to part-timers who work 20 hours or more per week. But the decision is up to the employer.
