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.
The Bureau of Labor Statistics defines part-time status as working on average between one and 34 hours per week. In the end, it is up to the employer to decide how many hours is part time and how many would make the job a full-time position. The Department of Labor does not differentiate between the two statuses. Part-time jobs can be found in all industries, but are most common in restaurant, retail and hospitality positions.
