Question

\(\huge \sf \color{plum}{ Journey~ from~ DNA~ to~ Protein}\)
Part 2: \(\sf \color{lightsalmon}{Transcription }\)

Answer 1

We went through the \(\sf \color{tan}{structures~ of~ DNA~ and~ RNA}\) in part1 of this tutorial. If you have not gone through it and don't know about it, make sure to go through it :

Now we can proceed
Transcription is \(\sf \color{turquoise}{making ~of~ mRNA~ using~ DNA~ strand~ as~ a~ template. }\)

Now before going into details
You should know regions on DNA
\(\sf \color{blueviolet}{Axon}\) - coding region
\(\sf \color{#FF7F50}{Intron}\) - non-coding region
\(\sf \color{brown}{Promoter}\) - region of DNA that is responsible for initiating transcription of a particular gene, and thus is located near transcription start sites: \(\sf \color{#FFD700}{TATA~box}\), on the same strand and upstream on the DNA.
As an addition, there are terms referring to direction in which transcription takes place: \(\sf \color{#CD5C5C}{Upstream}\) & \(\sf \color{#800000}{Downstream}\)
\(\sf \color{#CD5C5C}{Upstream}\) is toward the 5' end of the RNA molecule and \(\sf \color{#800000}{Downstream}\) is toward the 3' end.

Answer 2

When considering double-stranded DNA, \(\sf \color{#CD5C5C}{Upstream}\) is toward the 5' end of the coding strand for the gene in question and \(\sf \color{#800000}{Downstream}\) is toward the 3' end. Due to the anti-parallel nature of DNA, this means the 3' end of the template strand is \(\sf \color{#CD5C5C}{Upstream}\) of the gene and the 5' end is \(\sf \color{#800000}{Downstream}\).

Answer 3

Remember:
\(\sf \color{red}{DNA~ Replication~ and ~Transcription~ always ~happen ~in ~5'~ to~ 3' ~direction}\) - Upstream (in case if anyone wants tutorial on DNA replication- let me know)

Answer 4

So these are the regions of DNA

Answer 5

very nice. i like it

Answer 6

AWESOME!
perfect that's what kind of tutorial i wanted to see
latex diff colors just PERFECT!!

Answer 7

and gO_Od info! :-)

Answer 8

doin my best to make it easy and attractive at the same time :D
