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'.
Bacteria primarily have circular, double-stranded DNA that is not enclosed within a nucleus, distinguishing them from eukaryotic organisms. Additionally, many bacteria contain plasmids, which are small, circular DNA molecules that can carry genes for traits such as antibiotic resistance. Unlike eukaryotic cells, bacteria often undergo horizontal gene transfer, allowing them to exchange genetic material with other bacteria, which contributes to genetic diversity and adaptability.
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

Genes control protein synthesis, control cell functions, and determine heredity.
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.
Telomeres
All cells have genes

Actually the genes on a chromosome closest to the telomeres are the most unstable because they can unravel.

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.
Introns are present in eukaryotic genes because they allow for alternative splicing, which enables a single gene to code for multiple proteins. This increases the diversity of proteins that can be produced from a single gene, allowing for greater complexity and regulation in eukaryotic organisms.
The genes of a eukaryotic organism are located in the nucleus, within the DNA of its chromosomes. In eukaryotic cells, DNA is organized into multiple linear chromosomes, which contain the genetic information necessary for the organism's growth, development, and functioning.
