In recent times, it has been shown that adult cells can be induced to become embryonic stem cells also
called "induced pluripotent stem cells" (iPS). To make this conversion, what has been done to the adult
cells? The nucleus of an embryonic stem cell is used to replace the nucleus of an adult cell.
a- cytoplasm from embryonic stem cells is injected into the adult cells.
b- The nucleus of an embryonic stem cell is used to replace the nucleus of an adult cell.
C. The adult cells must be fused with embryonic stem cells.
d- New genes are added to the adult cell to convert it to an embryonic stem cell.
bacteria.
A new drug called Transacter has been developed to prevent protein translation in bacteria.
Which catalyst does the drug inhibit?
a- Helicase
b- RNA polymerase
C- DNA Polymerase
d- Ribosome
RNA processing
a- A primary transcript in eukaryotic cells can have long stretches of noncoding RNA.
b- Exons are cut out before mRNA leaves the nucleus.
C- Prokaryotic cells and eukaryotic cells do RNA processing
