Marina86 [1]

Answer:

The correct answer will be-

3'- T U U C G C T T G U C G C T C C T G U U G -5'.

Explanation:

The formation of the mRNA from the template strand or anti-sense strand is known as the transcription.

The nucleotide in the mRNA is added in the same way as the DNA according to the Chargaff rules which states that A will bind to T and G will bind to C but instead of adenine in mRNA will add uracil.

On the basis of this, the mRNA strand will be-

template strand:  5' A T T G C G A A C T G C G A G G A C T T C- 3'

mRNA strand:     3'- T U U C G C T T G U C G C T C C T G U U G-5'.

Approximately 90% of human cancer cells exhibit significant levels of telomerase. Does this mean that telomerase is an oncogene?
alukav5142 [94]

Answer:

No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.

Explanation

telomerase is not responsible for causing  deregulation while oncogenes cause deregulation .

Telomeres length shorten after the cell division which stops them to divide again and cell die.

Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could  prevent senescence.
