Where does DNA replicated occur in eukaryotes?
in the nucleus
WHEN ARE CHROMOSOME (DNA) REPLICATED?
Interphase is when DNA replication occurs. :)
Is it true mutations can only occur during interphase?
Mutations can occur at any time during the cell cycle, but they are most commonly associated with interphase when DNA is being replicated. During DNA replication in the S phase of interphase, errors can happen, leading to mutations. Additionally, exposure to mutagens or DNA damage can cause mutations during other phases of the cell cycle, including mitosis. Therefore, while interphase is a key time for mutations, it is not the only phase where they can occur.
When DNA replicated in a cell?
S phase
Does chromosome replication occur in mitosis and meiosis?
Chromosome replication occurs before both mitosis and meiosis. During the S phase of the cell cycle, DNA is replicated in preparation for cell division. In mitosis, replicated chromosomes are separated into two identical daughter cells, while in meiosis, replicated chromosomes are separated twice to produce haploid gametes.
Where does DNA replicated occur in eukaryotes?
in the nucleus
Do most mutations occur when DNA is being replicated?
yes
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
Name 2 errors that can occur during meiosis?
They include: incorrect copying of the DNA sequence when the DNA is replicated before division, and errors during recombination. If an error occurs in a sperm or an egg, the individual created from that gamete will have the change in every cell of their body.
Why DNA have to replicated before cell division?
DNA replication must occur before cell division to make sure that the daughter cells are genetically identical.
What is before DNA?
What is DNA replicated before?
Mutations occur because of?
errors in DNA replication
DNA is replicated where.?
interphase
Mitochondrial DNA is replicated independently from nuclear DNA?
Yes
WHEN ARE CHROMOSOME (DNA) REPLICATED?
Interphase is when DNA replication occurs. :)
Mutations in DNA often occur during replication. During which phase of the cell cycle do such mutations occur?
Genetic mutations occur during the S phase of the cell cycle (during interphase before mitosis or meiosis begins). This is when DNA is replicated, so any error would cause a mutation in the genetic code. Chromosomal nondisjunction is the failure of replicated chromosomes to separate, which causes extra or missing chromosomes in the daughter cells. This mutation can occur during meiosis I or II and during mitosis.
What phase is DNA replicated in?
DNA is replicated in the S phase of Interphase
