Question

In a cancerous cell, you would expect telomerase activity to be

Select one:

a. Higher than in a healthy cell

b. Lower than in a healthy cell

c. The same as in a healthy cell

------------

In his experiments, Mendel sometimes crossed tall pea plants with short ones. The outcome of such crosses would always express the dominant allele (either tall or short). If the outcome of such a cross had been a medium size (basically between tall and short), the pattern of inheritance for these plants would most likely be called

Select one:

a. Pleiotropy

b. Epistasis

c. Incomplete dominance

d. Codominance

e. Polygenic inheritance

-----------

Specific growth factors have the ability to induce the expression of specific cyclins and CDKs required during the various phases of the cell cycle

Select one:

a. True

b. False

---------------

Telomerase contains a template of RNA nucleotides

Select one:

a. False

b. True

Answer 1

Ans-

• A) higher than in healthy cell

Telomerase is an enzyme whose activity is seen higher in cancerous cell as result it divides continuously. As there is termination extension of DNA in each replication cycle by telomerase

• D) Codominance

In codominance pattern both the genes are equally expressed and thus we get blend of the characteristics as seen in above example

• A) True

Specific growth factors such as Maturation promoting factors controls the expression of the cyclins and CDKs that required in the phases of cell cycle

• B) True

Telomerase contain primer of RNA nucleotide and reverse transcriptase enzyme which cause RNA dependent DNA polymerization
