Explanation:
Telomere may be defined as the repetitive DNA sequence present at the ends of the chromosomes. Telomeres consists of the nucleotide sequence rich in G and consists of vertebrate sequence AGGGTT.
The mutation in telomerase enzyme can cause the excessive replication of the telomeres. These leads to the excessive cellular proliferation and makes the cell immortal. This extensive growth of telomere is one of the maine reason of the cancer development.
Thus, the correct answer is option (d).
The type of ion channels responsible for the depolarization phase of an action potential are Na+ (sodium)
channels. Sodium ions flow inward through the sodium channels and cause an
increase in the concentration of positively charged ions in the cell; this in
turn, leads to depolarization.
That they are both theories of evolutionary change, but the tempo of the change is different enough that we have the two theories. Rapid evolutionary change punctuated with long periods of stasis describes the former while gradual and incremental change over long periods is the description of the later. Natural selection seems to be more important in gradualism than punctuation, but this is <span>a murky area that is argued about often.</span>
