Why do chromosomes need to become 2 strands before the cell divides?
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
What is an original chromosome and its copy called?
it is called replication
How does a DNA molecule make a exact copy of itself?
they break apart and they find other DNA strands and form more DNA strands.
What does a replicate chromosome consist of?
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
What is the relationship between chromaids and chromosomes?
Normally a cells chromosomes are single strands - a bit like a pice of string. Just prior to cell division, a chromosome replicates (=makes another copy of itself) and these two copies are joined together at a point called the centromere. Each copy is now called a chromatid and being joined at the centromere make the familiar "X" shape, with each copy (chromatid) forming a side of the X and will have exactly the same sequence of genes down its length as the other chromatid (they are copies!). In cell division the copies (chromatids) will be pulled apart (X becomes > <) to become chromosomes in their own right.

When the chromosome makes a copy of itself it is said to what?
duplicate or replicate
What is an original chromosome and its copy called?
it is called replication
What step does each chromosome form an exact copy of itself?
Interphase
How a molecule of DNA makes an exact copy of itself?
they break apart and they find other DNA strands and form more DNA strands.

Are joined strands of duplicated genetic material?
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
What does a replicate chromosome consist of?
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
What are 2 identical strands of genetic material?
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
How does a bacterial chromosome go through replication?
When strands separate and each are copied, the daughter genome gets one parental strand and one newly synthesized complementary copy.
What is the term for an individual who has an extra copy of one chromosome or is missing a chromosome - Is it something-'ploid'?
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
What does a chromosomes consists of?
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
