Does DNA have chromosomes in it or is it the other way around?
Chromosomes are constructed from Dna.
Describe some of the pieces of information that scientists discovered that contributed to the chromosome theory of inheritance?
At around 1900, biologists began to see parallels between the behavior of chromosomes and the behavior of Mendel's "factors" during sexual life cycles. They knew that chromosomes and genes are both present in pairs in diploid cells (Cells with 2n chromosomes, in humans n is 23), homologous chromosomes separate and alleles segregate during meiosis, and fertilization restores the paired condition for both chromosomes and genes. Hence the Chromosome Theory of Inheritance. Source: AP Biology Textbook by Campbell Reece
What must DNA do Before chromosomes can form?
DNA wraps around protein before chromosomes can form.
Of what are chromosomes composed?
Chromosomes are DNA wrapped around histones
What do chromosomes do for the cell?
it moves stuff around the cell
What is the process in which homologous chromosomes wrap around each around each and exchange DNA?
crossing over
What is the process in which homologous chromosomes wrapped around each other and exchange DNA?
crossing over
What is process in which homologous chromosome wrap around each and other exchange DNA?
crossing over
What occurs during prophase 1 of meiosis?
In Prophase I: - The duplicated chromatin condenses. Each chromosome consists of two, closely associated sister chromatids. - DNA is exchanged between homologous (similar) chromosomes in a process called 'homologous recombination'. - This often results in the non-sister chromatids crossing over*. The new combinations of DNA created during crossover are a significant source of genetic variation. *at points called chiasmata (plural; singular chiasma).
What homologous pairs of chromosomes line up in the middle of the spindle during meiosis name the phase one or two?
During Metaphase 1 the homologous pairs of chromosomes line up at the center of the cell. They arrange around the spindle during meiosis.
Does DNA have chromosomes in it or is it the other way around?
Chromosomes are constructed from Dna.
Where are the two sets of chromosomes located in telophase?
they are floating around in the nuclear membrane that has newly formed around them after the original cell has split in two due to mitosis. that is when the entire process starts again.
What stage does the nuclear envelope reform around the chromosomes?
In the cell cycle, the nuclear envelope reforms around each cluster of chromosomes in telophase.
What is the phase in meiosis?
The longest phase in meiosis is Meiosis 1.
What is exchange functions in marketing?
The process of marketing is centered around the functions of exchange. The exchange of Goods and services with monitory, or general benefits to the company. The exchange function consists of 3 different functions: Buying , assembling and selling. These functions have a common feature in one respect, that they are directly concerned with the change in ownership of goods.

Is DNA made if chromosomes?
No. DNA is what chromosomes are made of. DNA is wound around proteins like thread on a spool, but since DNA is one long"string", the DNA is wound around many protein "spools", all of which are connected by DNA. This string of DNA/protein "thread on spools" is wound around itself, and wound around itself, and wound around itself a lot more, then (after a pretty intricate process) Wala! You have a chromosome.
