There is twice as much DNA in a chromosome that has replicated than there was before replication.
The amount will be halved again at anaphase of the subsequent mitosis (or meiosis II), when the two halves (chromatids) of the chromosome separate, and each half is from then on referred to as a daughter chromosome.

∙ 13y agoA chromosome contains one molecule of DNA and histone proteins.
The DNA molecule is highly folded around special proteins called histones.

Actually, each chromosome contains one DNA molecule. The DNA molecule is made of two chains of nucleotides linked by hydrogen bonds and twisted around each other to form the famous 'double helix' structure.
This is clearly stated in textbooks of genetics eg Hartl, Essential Genetics: "Each eukaryotic chromosome contains a single DNA molecule of enormous length".

When will DNA be replicated?
:Before the cell divition cell needs to double its genetic meterial then the DNA is replicated.;
What will happen during DNA replication?
You DNA will be replicated
WHEN ARE CHROMOSOME (DNA) REPLICATED?
Interphase is when DNA replication occurs. :)
When is DNA duplicated and why is DNA duplicated?
DNA is replicated in the process called Mitosis and Meosis. DNA is replicated to make more cells. Your body will make cells if you have a cut, grow, etc..
Where does DNA replicated occur in eukaryotes?
in the nucleus
How much DNA would a gamete contain if the DNA was also replicated between meiosis you and meiosis ii?
twice the normal number of choromosomes
What phase is DNA replicated in?
DNA is replicated in the S phase of Interphase
When a strand of DNA is ATCG what would the complementary pairings be for the replicated strand of DNA?
TAGC.
What are the phases when a cell's DNA is replicated?
The cell's DNA is replicated during interphase.
What would happen if cells with mutated DNA replicated?
Cancer.
What is before DNA?
What is DNA replicated before?
When will DNA be replicated?
:Before the cell divition cell needs to double its genetic meterial then the DNA is replicated.;
DNA is replicated where.?
interphase
What will happen during DNA replication?
You DNA will be replicated
How much -in amount- is in a replicated DNA chromosome as to that in an unreplicated chromosome?
These two amounts are Equal.
What is the origin of each strand in the replicated DNA-?
