Question

Primase synthesizes short sequences of complementary to the strand. RNA; leading RNA; lagging DNA; lagging DNA; leading Which of the following is the mechanism by which most proteins transit the nuclear envelope? Passive diffusion through a nuclear pore Passive diffusion through the nuclear membrane phospholipid bilayer Active transport through a nuclear pore that is powered by the cleavage of glucose by the nuclear pore complex Active transport through a nuclear pore that is powered by cleavage of a GTP by a G protein involved in the transport process Active transport through a nuclear pore that is powered by phosphorylation of the protein being transported Where does the synthesis and processing of rRNA, and their assembly into ribosomal subunits occur? in the cytoplasm At several different places within the nucleus Synthesis and processing occurs in the cytoplasm and assembly occurs in the nucleus Synthesis and processing occurs in the nucleus and assembly occurs in the cytoplasm in the nucleolus Pyrimidine dimers block DNA replication and transcription, can be repaired by photoreactivation. Can be repaired by nucleotide-excision repair. All of the above

Explanation / Answer

Ans 1 b

Primase catalyses the synthesis of short RNA also known as primers which are complimentary to lagging strand of dna identical to leading strand. Its a very important enzyme in synthesis of DNA strand.
