== == = Cell nucleus = Eukaryotic organisms (animals, plants, fungi, and protists) store most of their DNA inside the cell nucleus and some of their DNA in organelles, such as mitochondria or chloroplasts. Prokaryotes (bacteria and archaea) store their DNA in the cytoplasm
No, DNA does not exist as a single chromosome in most organisms. Instead, DNA is typically organized into multiple chromosomes within the nucleus of a cell.
No - quite the opposite. The nucleus is where almost all of the DNA in a cell is found. Small amounts are also found in some organelles, such as mitochondria - and this is the only form of DNA found outside the nucleus.
there is no DNA in the cell nucleus however the cell nucleus is important to replicating a cell in DNA strand. (it supprots the chromatin that replicates the DNA)
A cell at the end of the first phase (G1) is preparing for DNA synthesis, while a cell at the end of the second phase (G2) has already replicated its DNA. At the end of G1, the cell has two copies of each chromosome, whereas at the end of G2, the cell has four copies, as it underwent DNA replication during the S phase.
The only cell in humans that does not have DNA is the red blood cell.
No, DNA does not exist as a single chromosome in most organisms. Instead, DNA is typically organized into multiple chromosomes within the nucleus of a cell.
DNA synthesis does not exist and what you are probably looking for cell reproduction or cell mitosis. In cell mitosis there are 6 phases which is interphase when the cell makes the centrioles and begins preparing for the duplication of DNA. In prophase DNA is copied from the nucleus, metaphase aligns the DNA for the split, anaphase separates the DNA and centrioles, and in telophase the cell splits into two separate DNA and centriole developing into 2 new cells.
DNA itself contains no organelles. It is simply a large molecule, however it codes for the production of organelles which exist either freely in the cell cyoplasm or attached to the cell nucleus.
It is more compact and is protected against certains types of damage.
Yes all living things, (starting from a cell) have chromosomes. chromosomes are found in DNA and if cells didn't have DNA they wouldn't exist.
DNA is not a cell.
No - quite the opposite. The nucleus is where almost all of the DNA in a cell is found. Small amounts are also found in some organelles, such as mitochondria - and this is the only form of DNA found outside the nucleus.

In multicellular organisms, DNA exists in the form of chromosomes, which are found within the nucleus of each cell. These chromosomes contain the genetic information necessary for the organism's development, growth, and function. Each cell receives a copy of the organism's DNA during cell division to ensure that genetic information is passed on to daughter cells.
The nucleus of a cell has the DNA
chromosomes are the DNA material of cell
•A cell takes in DNA from outside the cell. This external DNA becomes part of the cell's DNA
