What is the period called after telophase 1?
In cell division, the period after telophase 1 is called cytokinesis. It occurs at the end of either mitosis and meiosis,
Which of the following can cause a mutation in a gene?
An error in the repair of damaged DNA-Apex
What part of the cell does replication occur?
Replication occurs in the nucleus of a eukaryotic cell and in the cytoplasm of a prokaryotic cell. In eukaryotic cells, DNA replication takes place in the nucleus where the genetic material is located, while in prokaryotic cells, replication occurs in the cytoplasm since they lack a true nucleus.
What is the 2nd step of DNA replication?
The 2nd step of DNA replication is initiation, where the double helix unwinds and the DNA strands are separated by an enzyme called helicase. This forms the replication fork where new DNA strands will be synthesized.
What does semi conservation mean in terms of DNA replication?
Semi-conservative replication means that when DNA replicates, each new DNA molecule contains one strand from the original DNA molecule and one newly synthesized strand. This process helps maintain the accuracy of genetic information during cell division.
Is inter-phase a stage of nuclear division?
I know one of them is replication of the DNA
What is the period called after telophase 1?
In cell division, the period after telophase 1 is called cytokinesis. It occurs at the end of either mitosis and meiosis,
DNA replication takes place when?
DNA replication takes place when preceding interphase.
When does replication occur?
Biological replication is of two types 1: DNA replicationwhich occurs in nucleus during S stage of Interphase of cell cycle before cell division and 2 : cell division is considered cell replication .
How does DNA semi-conservative replication help prevent mutations in DNA replication?
Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.
What is the error rate in the DNA replication process for eukaryotes?
The error rate in DNA replication for eukaryotes is approximately 1 in 10 billion nucleotides, thanks to the high fidelity of DNA polymerases and various proofreading mechanisms. Despite this low error rate, mistakes can still occur, which are often corrected by DNA repair pathways. Overall, the combination of accurate replication and repair systems helps maintain genomic integrity in eukaryotic cells.
What is the first step of DNA replication?
1. Interphase: replication and growth of the chromosomes occur. 2. Prophase: the chromatin condenses to see the individual chromosomes and centrioles move toward the opposite poles of the cell and spindle fibers grow. 3. Metaphase: the chromosomes align in the center of the cell. 4. Anaphase: spindles attach to the chromosomes and split them in part towards the opposite poles. 5. Telophase: the cell begins to separate into to new daughter cells. 6. Cytokinesis: the nucleus begins to form and the cells are completely cut off from each other.
Which of the following can cause a mutation in a gene?
An error in the repair of damaged DNA-Apex
What happens During replication DNA .?
During DNA replication the following occurs: 1) An enzyme called helicase separates the DNA strands (the space where they separate is called the replication fork). 2) DNA polymerase adds complementary nucleotides to the separated strand of DNA. 3) The DNA polymerase enzyme finishes adding nucleotides and there are two identical DNA molecules.
Process by which DNA copies itself?
Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
