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: a hard sedimentary rock, composed mainly of calcium carbonate or dolomite, used as building material and in the making of cement.
Answer: it is called Bradycardia.
Explanation:
Bradycardia is a slower that normal heart rate. The heart rate of adult human usually beats between 60 to 100 per minutes . A testing heart rate less than 60 beats per minutes is called Bradycardia with the exception of Adult in deep sleep. It could be a serious problem if the heart could not pump oxygen rich blood to the body. It is caused by damaged of heart tissues from heart disease or due to aging. Heart disorder from birth or infection of heart tissue
