What characteristics of DNA results in cell differentiation in developing embryos?
Elina [12.6K]

Hi!


The correct option is B. Which genes are active.


Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.

But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.


Hope this helps!

Explain how environmental agents such as chemicals and radiation cause cancer.
Paul [167]

Chemical (mutagens) usually either mimic the structure of nucleotides and are inserted in DNA or either cause chemical changes  (such as alkylation) in nucleotides hence causing mismatching during replication. Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an increased likelihood of mutations during the repair of the DNA by cell mechanisms.
