part of Eukaryotic cell where formation and action of primase take place respectively ?
A nucleoplasm and cytoplasm
B cytoplasm only
C nucleoplasm only
Answers
Answer:
By the action of free cytoplasmic ribosomes, Primase is synthesized in the cytoplasm of an eukaryotic cells. In the nucleoplasm, Primase performs the function of synthesis of oligonucleotides which is required for the DNA synthesis.
Therefore, the option (a) is correct.
Explanation:
Primase is an enzyme that catalyzes the synthesis short RNA sequences named Primers.
- Primers act as a beginning point for DNA synthesis. Primase is an RNA polymerase because it develops RNA molecules.
- Primase works by generating short RNA sequences that are complementary primer to a single strand of DNA (ssDNA) that serves as its template.
- Before DNA replication can occur, Primers must be synthesized by primase. Enzymes that synthesize DNA are known as DNA polymerases. They can only attach new nucleotides to an existing strand of nucleotides.
- Therefore, Primase provides a primary groundwork for DNA synthesis.
- Primer is formed from ribonucleoside triphosphates present in cytoplasm. They have a length of approximately four to fifteen nucleotides.
- They act in the nucleoplasm of a cell because they are involved in DNA synthesis.

Answer:
A) nucleoplasm and cytoplasm
Explanation:
By the movement of unfastened cytoplasmic ribosomes, Primase is synthesized withinside the cytoplasm of an eukaryotic cells. In the nucleoplasm, Primase plays the feature of synthesis of oligonucleotides that is required for the DNA synthesis.
Therefore, the option (a) is correct.
Explanation:
Primase is an enzyme that catalyzes the synthesis brief RNA sequences named Primers.
Primers act as a starting factor for DNA synthesis. Primase is an RNA polymerase as it develops RNA molecules.
Primase works via way of means of producing brief RNA sequences which can be complementary primer to a unmarried strand of DNA (ssDNA) that serves as its template.
Before DNA replication can occur, Primers ought to be synthesized via way of means of primase. Enzymes that synthesize DNA are referred to as DNA polymerases. They can handiest connect new nucleotides to an current strand of nucleotides.
Therefore, Primase presents a number one basis for DNA synthesis.
Primer is fashioned from ribonucleoside triphosphates found in cytoplasm. They have a period of about 4 to 15 nucleotides.
They act withinside the nucleoplasm of a mobileular due to the fact they may be worried in DNA synthesis.
