There are different types of stem cells such as the Embryonic stem cells, Non-embryonic (adult) stem cells, Cord blood stem cells and amniotic fluid stem cells etc.

Why mouse cannot die with Rough strain? reason
The rough strain didn’t had the required ability to kill the mice but when it acquired genetic material from the smooth strain so it was transformed and was able to kill the mice.

Why bacteriophage require bacteria for it`s reproduction?

One gene is for one trait or multiple genes for one trait?
Starting codon are same for all protein process?
Which cell is used for hens wing transformed into hens leg?
One gene for one trait is possible while its also possible that mutiple genes control a single trait and this phenomenon is called as Polygenic inheritance.
AUG is the most common START codon and it codes for the amino acid methionine (Met) in eukaryotes and formyl methionine (fMet) in prokaryotes.
Pitx1 or Tbx4 are thought to be responsibkle for leg development in hen.

Does RNA contain nucleosides?
Our DNA is matched only from our parents or also our paternal and maternal family?
A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group so it can be present in DNA or RNA. Also, DNA can be matched with our parents but some features and characters are present throughout the family as you may have known and seen that many families have a particulkar disease running through them like Diabetes, Blood pressure issues, Hairfall etc.
