What is the protective cap of DNA on the tip of chromosomes?
The telomere is the protective cap of DNA on the tip of chromosomes. You lose a small amount of these telomeres each time the cell divides. Eventually the telomeres be lost as you age. Short chromosomes because of lack telomeres are one reason aging occurs.
Why do prokaryotic chromosomes not have telomeres?
because it has its own modification and restriction system which prevents its own DNA from degradation as telomeres are mainly responsible to protect the DNA from exonuclease activity of DNase.
In a diploid cell in which 2n equals 14 how many telomeres are there in each of the follow phases of the cell cycle a. G1 b. G2 c. mitotic prophase d. mitotic telophase?
There are two telomeres for each chromosome, so you need to figure out how many chromosomes there are at each stage and multiply that by two. G1-- growth phase: 14 chromosomes = 28 telomeres G2-- growth phase after replication in S phase: 28 chromosomes= 56 telomeres Mitotic Prophase-- before cell division, nuclear membrane disappears: 28 chromosomes= 56 telomeres Mitotic telophase-- nuclei separate: 14 chromosomes = 28 telomeres
Is there a way to keep the telomeres from shortening?
the enzyme telomerase is used to stop the shortening of the telomeres. a good example is when a cell becomes cancerous the body will release telomerase so the cell wont die
What enzyme makes it less likely that DNA will be lost from telomeres during replication?
DNA Polerase

What is a telomere and how does it affect cloned animals?
Telomeres are DNA sequences at both ends of a chromosomes that shrink in length every time the DNA is copied. In cloned animals the telomeres are usually longer than those of the same animal naturally conceived.

Is obesity related to telomeres?
Yes. We all begin as 1 cell and as it divides the telomeres become shorter. Larger people have more cells than smaller people and therefore have shorter telomeres.
What is the base word of lengthen?
The base word for lengthen is long > length > lengthen
