Telomeres solve the end replication problem by extending the 3' end of the chromosome. Without them, the 3' end can't be replicated since replication is 5' to 3'.

What are the social issues disadvantages of cloning plants in tissue culture?
Well, a lot of it is in speculation right now, but one disadvantage has to do with telomeres.At the ends of each of your chromosomes there are long 'buffer zones' where there are a lot of nucleotides, but no actual genes. These are called telomeres Everytime your DNA replicates during cell divison, bits of these buffer zones break off. This is okay, because again, it these 'buffers' don't carry any information. The problem is, eventually you DO start loosing information because the telomeres run out. This is linked to aging.Dolly the sheep, for example, died at only age 6 (most sheep live to be about 2) and one of the things that they noticed was that she had shortened telomeres, because her chromosomes originally started from an adult sheep; they hadn't been brand new at her conception.As it turned out, she had problems like arthritis and such that you would expect from a much older animal

What is the functions of genes?
Genes control protein synthesis, control cell functions, and determine heredity.
What is jellyfish genes used for?
Jellyfish genes are used within genetically engineering certain foods. The jellyfish genes are added to wheat to make the wheat glow when it needs water.
Why do common patterns of genetic control for development exist in animals?
They exist because all these genes have descended from the genes of common ancestors.
What helps to prevent the loss of genes?
Telomeres
Do eukaryotic cells have genes?
All cells have genes
When will be first experiment on humans to stop all genes of aging?
It is difficult to predict when the first experiment on humans to stop all genes of aging will take place, as such a development would need thorough testing and ethical considerations. Research is ongoing in the field of aging and genetics, but more time and studies are needed before reaching a point where interventions on all aging genes would be feasible in humans.
What are benefits of preserving biodiversity?
genes
Why is telomeric chromosome unstable?
Actually the genes on a chromosome closest to the telomeres are the most unstable because they can unravel.
What are eukaryotic genes composed of?
I belive is DNa.
The chromosomes of eukaryotic cells have more?
genes
Are most eukaryotic genes controlled individuallyor as groups?
indivdually
When you clone an organism why is it the same age as its genetic parent?
It's not. If done right you have a new organism. But if your source has shortened telomeres (tags on genes), then the resultant offspring will start life with shortened telomeres. It still starts as an infant, but its life expectancy is shortened.
Name the sections of eukaryotic genes that are transcribed and translated?
introns and exons
Why do eukaryotic genes have introns but introns are absent from prokaryotic cells?
Look at the sheer amount of DNA that is contained into a eukaryotic gene (eukaryotes have more DNA to code for and so they can leave some of the DNA out, also look at the way the DNA is formed i.e. Eukaryotic genes are double stranded helixes and prokayrotic genes are a single strand of circular dna.
What do the chromosomes of eukaryotic cell have more of than those of a prokaryotic cell?
Genes
