Question 1

What is the telomere and cosist of what
Where it found
Function

Answer 1

Specialized DNA cap
Consist of a hundred or thousands of repeated of the same short DNA 🧬 sequence which varies between organisms but is 5 TTAGGG3 in humans
Present in the tip of eukaryotic chromosome

Telomere act as a cap that protect internal region of chromosomes and they worn down a small amount in each round of dna replication

Question 2

Telomeres
Does the length of telomere effect

Answer 2

Protein dna complexes that cap ends of eukaryotic chromosome
Maintenance of the length of the telomeres is essential for genomic stability and cell viability

Question 3

Telomere shortening correlate with
Majority of cancer cells depend on

Answer 3

Cellular aging
Activation of telomerase to gain proliferative immortality

Question 4

Telomerase

Answer 4

An enzyme that extend the telomeres of chromosome is an RNA DEPENDENT DNA POLYMERASE meaning an enzyme that can make dna 🧬 using RNA as a template
