A simplified model of protein synthesis is shown here: How might this model be revised to show a more accurate depiction of prot
ein synthesis?
Prior to process 1, DNA should copy itself to allow the cell to divide
After process 2, the completed protein should travel back to the nucleus
Between processes 1 and 2, the mRNA must be modified before leaving the
nucleus
During process 2, the ribosome should remove any mutated nucleotides
from the mRNA
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.
Viruses do not possess any machinery necessary for the purpose of their reproduction.
They only possess their genetic material enclosed within a capsid structure.
The capsid is constituted of glycoproteins.
They completely depend upon the components and organelles of the host cells whom they infect to help them carry out their reproduction process.
After infecting a host cell, the viruses hijack all the machinery and components of the host cell and use them for the purpose of transcribing their genetic material (DNA or deoxyribonucleic acid) to produce the virus-specific mRNAs (messenger Ribonucleic Acid).
These mRNAs are further translated into virus-specific proteins using the host-specific Ribosomes. These virus-specific proteins are required for replicating the viral genetic material and producing the capsid structure.
The virus-specific proteins and glycoproteins are synthesized by utilizing the raw materials from the host cells.
Transcription is the process by which an enzyme called RNA polymerase or DNA dependent RNA polymerase copies the protein coding region of the DNA (gene) in the form of an RNA sequence (mRNA).
The synthesis of the mRNA happens in the 5' to 3' direction. This mRNA is further recognized and converted into the amino acid sequence with the help of the Ribosome.
The amino acid sequence folds to give rise to the protein.
Because water helps them grow.. when you poue water on a flower is suks the water in and then it goes underground and the soils suk it in and grow 10 cm every day you water them
