Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer(HGT) is mainly seen in bacteria. Bacteria exchange their genetic material from the horizontal gene transfer method. There are three methods in HGT- conjugation, transduction, and transformation.
In conjugation, the bacteria exchange their plasmid through sex pilus. In transformation, bacteria take up other's genetic material from its environment and in transduction virus-mediated gene transfer occurs.
Therefore in bacteria and nucleus, the genetic material exchange can occur only through HGT.
Answer:
D) most phosphorus in the environment is bound to carbon, nitrogen and hydrogen
Pre-mRNA is the polymer is synthesized during transcription, it is different from polymer being copied in having U instead of A.
A DNA fragment is copied into RNA during transcription. Messenger RNA is the term for DNA segments that are translated into RNA molecules that can encode proteins. Non-coding RNAs are RNA molecules that contain copies of additional DNA segments. Only 1% to 3% of all RNA samples are mRNA.
