what are chromosomes useful for?

They keep a record of who you are, and pass on that record to your offspring.  DNA, which is contained in your chromosomes, is the program to create a human being.  The program is rewritten every time a new person is created, but the subroutines, if you will, come from their parents.  Useful if you want to continue the human race!

CHECK THE NUMBER OF CHROMOSOMES OF HUMAN, IT IS FIXED AT 48, BUT HUMAN WITH MORE OR LESS NUMBER OF CHROMSOMES TEND TO DEVELOPED OTHER PHYSICAL FEATURES THAT IS CONSIDERED ABNORMAL.OTHER ANIMALS HAVE THEIR NORMAL NUMBER OF CHROMOSOMES THAT INFLUENCED THEIR PHYSICAL FEATURES INCLUDING THE NUMBER OF FINGERS.

Are you asking about chromosome transformations such as rearrangements and translocations?

the chromosomes group together.

Ahhh, no. Why would they? They don'thave 47 chromosomes.

I do not know alot about them, but I do know that spindle proteins are used in cell division to move the chromatids.\n\nSee http://www.scienceaid.co.uk/celldivision.html for more about cell division and spindle proteins.

46 chromosomes or 23 pairs of chromosomes per cell, consisting of 22 pairs of autosomes, and two sex chromosomes; considering the body has over a trillion cells...\n That is basically 46,000,000,000,000 chromosomes!\nThere are some rare cases when there is an extra chromosome(ex: Downsyndrome) or one less chromosome in each cell.

Because it helped us to understand the mechanism by which cells and organisms pass information from parent to offspring.  It also opened the door for research that can help prevent and cure genetic diseases caused by mistakes made during DNA replication, etc.

Normal male cells have 23 pairs of chromosomes (1-22 & X+Y) or 46 total chromosomes.

Your genome is your genetical makeup.  Your genes tell your body what to do most of the time.  Genes are responsbile for telling the body how to do things.  They are like the blue print to your body.

Spindle fibers attach to chromosomes.

Chromosomes are strands of DNA. Genes are sections of DNA. So a chromosome is made up of DNA and has many genes on it. Genetic means "of or relating to genes". So, yes, eye color and hair color is genetic, and the genes that determine these traits are in chromosomes. You should read about genetics in a biology textbook or online. Here's a website that talks about genetics in a simple, easy to understand way:\nhttp://www.purchon.com/biology/genetics.htm\n\nI have hair that's light brown and I have blue eyes, so I'd be B.

Meiosis results in the production of haploid cells, with half of the regular number of chromosomes (23 singles onstead of 23 pairs). These mature into the male and female gametes, which then go off and try to find a complementary set of the opposite sex to hook up with, to become whole again. Hence meiosis allows for genetic coupling of non-identical DNA, resulting in an offspring which has the genetic material of two separate individuals. With only mitotis, there is no sharing of material, just division.\nSharing of material allows for diversity within a population. Populations which are diverse are more likely to survive variations in environment, to have people who can protect others if need be, who can lead if need be, who might have inate resistance to diseases if need be etc etc. So the whole population benefits because of the diversity afforded by meiosis. Clonal populations, produced by mitotis alone, would eventually come across a disease or natural disaster which would affect everyone equally, wiping them all out. \n\nHope this helps.

we have cells.cells contain nucleus.nucleus has chromayin network.chromatin network is actually  chromosomes.chromosomes have  genes located on them at specific places called locus.these genes nothing but nucleotide sequences that determine our various characters like height,weight,eye colour etc.they contain codes for specific proteins in our body.any damage to it in the form of mutation we are affected by terriblre diseases.thats the long and short of it.

I honestly do not know, but "chromosoms" has an E: chromosomes.

Scientists know the tobacco genome. When doing genetic studies, scientists can tell which genes are where, where to cut and splice and add things, and can determine if there are problems with the plant's DNA. Pretty much, tobacco is useful because we know it and it makes a great reference value.

Diploid. All cells in the body that have chromosomes, except germ line cells, are diploid. One set of chromosomes from each parent.
