|
|
Shorter telomeres correlate to shorter cell lifespan
|
|
|
Longer telomeres allow cells to replicate more often
|
|
|
Generally speaking, the more often a cell replicates the shorter the telomeres become
|
|
|
Telomeres are very stable in their length for most body cells
|
Detailed explanation-1: -Note that in replication, the telomeres prevent the shortening of the DNA. Therefore, the statement that says the telomeres consist of DNA and sugars is incorrect.
Detailed explanation-2: -Which of the following statements are true regarding telomeres? Telomeres contain non-essential genes that are not necessary for cell survival. Telomeres are enzymes that repair telomerases (which cap the end of linear chromosomes).
Detailed explanation-3: -(b) The length of telomeres varies between species, so it is impossible to predict how the length of an individual’s telomeres compares with the length of telomeres in an older individual of another species.
Detailed explanation-4: -Which one of the following statements correctly describes telomerase? Telomerase creastes repetitive DNA at the end of the chromosomes.
