Proteins
synthesis requires transcription of DNA (containing information) to mRNA then
this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together
with ribosome and tRNA to synthesize proteins. Further steps are the following:
1)
One side of DNA strand is copied to become mRNA (messenger RNA).
2)
mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome.
3)
mRNA works with ribosome’s 3 bases at the same time.
4)
tRNA (transfer RNA) connects with available DNA bases.
<span>5) tRNA
releases the amino acids which in turn combines with the other produced amino
acid chains from different DNAs. </span>
The correct answer is D. Cannot stand as a sentence.
Subordinate clauses convey no meaning when left alone and must always be used in combination with independent clauses so as to create a complex sentence that conveys meaning.
