lecture 5
mRNA production occur in nucleus,but it's function in ribosomes and it's giuded by special eupkaryotic str. that exist in the 5 prime end a chemical str. called cap and it exist for two purposes:
(protection\recognetion).
Genome : all DNA that is present in organism
the number of nucleotides(bp): it's not proportional to number of genes ,it doesn't mean that the more chr. the more the number of genes .
there's no different in gens b\w human (healthy individuals)
-gene expression=transcription+translation(in case of protein only)
because for example tRNA ,rRNA,and snRNA are only transcribed.
-RNA polymerase synthesize the RNA strand in direction of 5prime to 3 prime
-promotor is never transcribed(receive receptor hormone complex ,and regulate the process)
-the genes and promoters are the same in each cell for the same gene ,but what make the promoter start a transcription of same genes differntly is the transcription factors and acticvators
-holoenzyme:is very imp. recognize promoter region.
-difference b\w replication &transcription is very imp.

زملاؤنا المتقدمين لامتحان BC142، هذه بعض الحاجات اللي ممكن تفيدكم:
تفريغـات لمحاضرات دكتور عبّاس، يُعتبر د.عبّاس عقبري البايوكيمستري في مصر، ويوصل في المعلومة بطريقة سلسة ولا تُنسى، وأنا شخصيًّا استفدت منّه في شابتر الأمينو ميتابوليزم، وكانت الأسئلة ساهلة -في نظري- بالرغم من صعوبتها.
