Answer:
When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.
The answer would be “D,” as gravity is the force that keep all objects on Earth’s surface.
The DNA copies are moved to opposite ends of the cell.
Meiosis I produces 2 haploid cells and meiosis II produces four haploid cells.
