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>
Answer:
B
America is a united country despite its cultural differences
Explanation:
As the title ¨A Quilt of a Country¨ already explains, America - it would be more correctly to use U.S. by the way - is a multicultural layer of different peoples, beliefs and races, joined together. Although the problems caused by this quilt society are manyfolded, like for instance the idea of a national identity that might evaporate, in the end there is a sense of hope and not of despair when Terrorism is leading to unity.
