Answer:
True.
When shopping for fruit trees for the yard we should select varieties that mature before the hot summer temperatures arrive to avoid sunburning fruit.
Explanation:
- The fruit trees on your yard should be carefully selected, always seek for the fruit that matures before the summer season.
- The summer season hot weather is most likely to burn down the tree and may also kill it before it can grow.
- Once it gets matured then there is no drastic effect of sun so, we must select tree in such a manner that it must get matured before hot summer.
Tobacco mosaic virus (TMV) is a simple rod-shaped helical virus that contains single stranded RNA situated at its middle and is surrounded by a protein coat called capsid. After tobacco mosaic virus enters its infected host cells through mechanical inoculation, it removes its capsid to release its single stranded viral nucleic acid which is then transported into the nucleolus. The single stranded viral RNA actuates the production of specific enzymes (RNA polymerases) and it also produces another RNA strand (replicative RNA). The new viral-RNAs are transported from the nucleus into the cytoplasm and functions as messenger-RNAs (mRNAs). Each mRNA, ribosomes, and t-RNA, of the infected host cell all controls the production of protein subunits (capsomeres). After the production of the preferred capsomeres, the new viral-RNAs arrange the capsomeres around it which lead to the production of a complete virus particle (virion). The viruses then migrate from one cell to another. Hence, creating organized infection.
Answer:
No. Instead they contain enzymes.
