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>

EFFECT OF GROWING LOADSHEDDING ON STUDENTS.
Dear Mr. Adam, recently, there have been an increase in loadshedding which initially was supposed to be a one-time thing but has turned out to be frequent.
This growing loadshedding is affecting students because we don't have electricity to even study and do homeworks, research or class projects.
This has also affected the WiFi as when the electricity is out, the WiFi becomes unstable and downright unusable.
There has also been an increase in discomfort among the students as this has led to sleep disruptions especially as this is done at the height of summer when the air conditioning is most needed.
Please, I want you to bring this problem to the mass media so a solution will be provided. Thank you.
Yours faithfully,
Charlie Adam.
