When a cell is preparing to divide in order for its daughter cell to have all its information it must oversee the what of its DNA so that a double dose of genes is present for a brief period?
The cell must oversee the replication of its DNA so that each daughter cell receives a complete set of genetic information. This replication process ensures that there is a temporary double dose of genes during cell division, allowing for accurate transmission of genetic material to the daughter cells.
Does mitosis allow genes to move from one chromosome to another?
No, mitosis does not allow genes to move from one chromosome to another. Mitosis is a type of cell division that results in two daughter cells each having the same number and type of chromosomes as the parent cell. Genes are not moved between chromosomes during this process.
What is an example of a constitutive gene or set of genes and why is it important?
Housekeeping genes, such as those involved in basic cellular functions like metabolism or DNA replication, are constitutive genes that are continuously expressed in all cells. These genes are important because they provide the foundation for essential cellular processes to occur, ensuring the normal functioning and survival of the organism.
Checkpoint genes encoding protein that stimulate mitosis are called what?
Checkpoint genes encoding proteins that stimulate mitosis are called cyclins and cyclin-dependent kinases (CDKs). These proteins work together to regulate the progression through different phases of the cell cycle, including the transition from G2 phase to mitosis.
Are the genes in daughter cells produced by mitoses the same as or different from the genes in the original cell?
The genes in daughter cells produced by mitosis are the same as the genes in the original cell. Mitosis is a process of cell division where the genetic material is replicated and evenly distributed between the daughter cells, ensuring that they have an identical genetic makeup to the original cell.
Does gene copies DNA strand for mitosis?
Yes. Genes are composed of DNA, and DNA replication occurs during interphase. This is when the chromosomes are doubled.
Why does replication have to occur?
So that the genes can be passed on.
How are telomeres important for preserving eukaryotic genes?
Telomeres solve the end replication problem by extending the 3' end of the chromosome. Without them, the 3' end can't be replicated since replication is 5' to 3'.
Checkpoint genes that stimulate mitosis are called?
oncogenes
Why do the function of cell differ mitosis?
the renetic genes are similar
When a cell is preparing to divide in order for its daughter cell to have all its information it must oversee the what of its DNA so that a double dose of genes is present for a brief period?

This replication process ensures that there is a temporary double dose of genes during cell division, allowing for accurate transmission of genetic material to the daughter cells.
How does genetic material undergo crossing over during meiosis or mitosis?
During meiosis, genetic material undergoes crossing over when homologous chromosomes exchange segments of DNA. This process increases genetic diversity by creating new combinations of genes. In mitosis, crossing over does not occur as it involves the replication and division of identical chromosomes.
What are some examples of interactions between genes and the environment?
Type one diabetes. Scientists know it has something to do with genes, but it also requires environmental factors such as a childhood virus AND extreme amounts of stress. Cancer is also caused by environmental factors that cause the DNA of a cell to warp, so it loses control of mitosis, or cell replication.
What is the first step in eukaryotic DNA replication?
1.) The 2 copies of DNA produced by replication in each chromosome remain closely associated until the cell enters prophase of mitosis. 2.) At that point, the chromosomes condense, and the two chromatids in each chromosome become clearly visible. 3.) They separate from each other in anaphase os mitosis, producing 2 cells, each with a complete set of genes coded in DNA.
Why would the storage of genetic information in genes help explain why chromosomes are separated so carefully during mitosis?
The careful separation in mitosis is supposed to ensure that both daughter cells recieve a full diploid complement of the chromosomes, i.e both daughter cells get all the genetic information from the parent's cells
Does mitosis allow genes to move from one chromosome to another?
No, mitosis does not allow genes to move from one chromosome to another. Mitosis is a type of cell division that results in two daughter cells each having the same number and type of chromosomes as the parent cell. Genes are not moved between chromosomes during this process.
What is most accurate about genes?
Genes are generally composed if DNA fragments.
