Answer:
characteristic of a region or climate that is frost-free with temperatures high enough to support year-round plant growth given sufficient moisture
Explanation:
Prophase the nuclear membrane disappears & after that Chromtains coil up & chromosomes are now visibles & lastly spindle fibers come & separate them.
That sounds like magnification needs to be applied.
Attain the length of a real DNA and then measure the length of your specimen.
Magnification=length of specimen
----------------------------
real length of DNA
Answer: To find suitable sites for projects
Explanation: A geologic map shows where these types of geologic materials are, to improve our stewardship of the Earth through informed agriculture, construction.
Answer:
Telomerase
Explanation:
Repetitive regions at the ends of Chromosomes are known as telomeres and these are crucial for chromosomal stability. There is no gene present and they provide protection to internal parts of chromosome. The telomeres are eaten up slowly by ‘DNA REPAIR MECHANISM’ after many division cycles, which is considered as ageing. That why, a cell can divide only certain number of times.
Some cells have ability to express an enzyme telomerase that maintain the length of telomere. The telomerase enzyme contributes to cell immortality by rebuilding the damaged telomere. Thus telomerase enzyme is necessary for cancer initiation and survival of tumor. Telomerase enzyme can make its own DNA by using its RNA as template
. It extends the overhang strands of DNA by using a comlementary DNA.
