The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.ence, DNA polymerase moves along the template strand in a 3'-5' direction, and the daughter strand is formed in a 5'-3' direction. This difference enables the resultant double-strand DNA formed to be composed of two DNA strands that are antiparallel to each other.
A salaried taxpayer is eligible to claim a house rent allowance (HRA) exemption under Section 10(13A) of the Income Tax Act, 1961, in respect of an accommodation occupied him, except where the residential accommodation is owned by him or he has not actually incurred the rent expenditure.
The VRA is a special authority by which agencies can appoint an eligible veteran without competition. The VRA is an excepted appointment to a position that is otherwise in the competitive service. After 2 years of satisfactory service, the veteran is converted to a career-conditional appointment in the competitive service. (Note, however, that a veteran may be given a noncompetitive temporary or term appointment based on VRA eligibility. These appointments do not lead to career jobs.) When two or more VRA applicants are preference eligibles, the agency must apply veterans' preference as required by law.
