C. deformation.
D. strain.
identifying genetic disorders
B)
determining the sex of an unborn child
C)
development of organs for transplantation
D)
studying the chromosomal changes during cell division
Answer:
The correct answer would be C) development of organs for transplantation.
Cell differentiation refers to a process by which a cell becomes specialized to perform a specific function. For example, a liver cell, blood cell, muscle cell et cetera.
In multi-cellular organisms, life starts with a single cell (zygote) which then divide and differentiate into various types of cells. The specialized cells synchronize to form tissue which then form a particular organ.
Thus, regulation of cell differentiation can lead to development of specific organ which can be used for transplantation.
Answer: C) development of organs for transplantation
Explanation: Stem cells are human cells that can develop into many different types of cells. Stem cell research includes regulating the process of cell differentiation and stem cells can be used in the development of organs.
Answer:
2, 4 , 1 and 3
Explanation:
The correct order for events in excision repair of DNA are:-
2, 4 , 1 and 3 that is the
1st step would be:
(2) Damaged bases are recognized.
2nd step of the process
(4) Part of a single strand is excised.
3rd step will be
(1) DNA polymerase I adds correct bases by 5¢ to 3¢ replication.
and the final step in excision repair of DNA is
(3) DNA ligase seals the new strand to existing DNA
