The chromosomes are actually chromatin (in a jumbled up mess) and then form into chromosomes during the G2 phase

How is the amount of DNA in the beginning of Mitosis different from the amount at the end?
The DNA doubles. heehee, long question, short answer. hope I helped. :3
The stage if the cell cycle where the cell grows replicated DNA and prepares for division is called?
The only way i can explain this is this way; Interphase this is the period between cell divisions ,the genetic material is in the form of CHROMATIN,this is spread throughout the nucleus of fine threads. Before the division begins,the DNA in the chromatin copies of itself,copy attached to the original. When DNA replictes, mitosis begins. Prophase. Chromatin is now visable as CHROMOSOMES,each chromosome has two identical parts as the DNA has duplicated and both parts still together. Membrane around the Nucleus disappears in the cytoplasm. METAPHASE Chromosomes attach to fibres at their midpoints. ANAPHASE The two identical halves of chromosomes split apart during anaphase,they are pulled to oppersite end of the cell. The number of chromosomes is the same at each end,the number that a complete cell is sapposed to have. TELOPHASE Chromosomes unwind and become chromatin again,new nuclear membranes are formed. Cytoplasm divides in the middle of the cell and have become two complete cells(daughter cells),each with the same number of chromosomes as the parent cell. hope this helps someone at least. jen
Telophase is the stage of cell division where?
There are 6 stages of mitosis (cell division) interphase, prophase, metaphase, anaphase, telophase and cytokenesis. Telophase is the stage in which after the chromosomes have gone to either end of the cell the chromosomes unraval to become DNA once again and two nuclear envelopes reform around the two groups of the DNA meaning the DNA has become enclosed into two seperate nuclei.
Name the three phases of interphase and describe an activity unique to each phase?
The three stages of interphase are Gap 1, Synthesis, and Gap 2. In both the gap stages, the cell grows in preparation; in Gap 1 it grows in preparation of Synthesis and protein synthesis occurs, and in Gap 2 it grows to prepare to divide in prophase. In the Synthesis phase, the DNA in the cell is copied so there are two sets of DNA in preparation of division.
In which of the stages does each chromosome consist of two DNA molecules?
(From the end of the S phase of interphase through the metaphase of mitosis). In eukaryotes, throughout the entire life of the Cell, also called the cell cycle. During Mitosis the chromosomes are separated.
In mitosis how many times is the DNA copied?
In both mitosis and meiosis DNA replication only occurs once, during Interphase and Interphase 1, for mitosis and meiosis, respectively.
How many cell are there at the end of interphase?
Just one, same as at the beginning of interphase.
How does a DNA model look?
At the end of a DNA extraction procedure, DNA can be spooled around a glass rod and looks like a white cotton-like, stringy mass.
How is the amount of DNA in the beginning of Mitosis different from the amount at the end?
The DNA doubles. heehee, long question, short answer. hope I helped. :3
How long does Interphase last?
The majority of the cell cycle is spent in interphase. There are three stage of interphase that end when a checkpoint is achieved, in totality 90 percent of the time or 20 hours of interphase.
What protein concentration controls beginning and end of interphase?
Cyclin
What forms at the center of a cell near the end of telophase?
it is the interphase
Cells nucleus during interphase?
DNA is always present in every stage of the cell cycle...reproducing it is the whole purpose of the cell cycle! In interphase, there are three phases: the cell grows (G1), duplicates each strand of DNA (S), and gets ready for mitosis (M). During the first part of interphase the chromosomes are long and thin, and single-stranded, making them very hard to see without a very powerful microscope. During the last 2 stages of interphase, the DNA is duplicated but is still long and thin. It is only in the prophase stage of mitosis that they are condensed enough to often be seen with a "normal" microscope on high power (400x) . By the end of mitosis, the doubled-chromosomes have been pulled apart and into opposite ends of the parent cell. When the cell has finished dividing, each "daughter cell" has the original number of single-stranded chromosomes. The chromosomes "uncoil", and the cell matures during G1 phase of interphase. Many people believe that DNA and/or Chromosomes (Chromosomes are made of DNA, remember.) are only present during mitosis. They just get fatter during mitosis by coiling tighter. Thus they are more easily seen. BUT.. just because you don't see them in interphase doesn't mean they aren't there!

What cell part is doubled or duplicated or copied at the end of interphase?
The chromosomes are copied.
What did Lady Gaga say at the end of Born This Way that sounded like save DNA?
Same DNA. We're born this way.
