The normal process of transcription requires:

[element41skater]

The normal process of transcription requires:
a) an AUG start codon b) an ATG start codon
c) ribonucleoside triphosphates d) template RNA

I think D because Transcription makes a template RNA

[Babybel56]

I'd be inclined to agree with you a. and c. are needed for translation and ATG doesn't code for a start codong.

[JackBean]

Babybel: are you sure? NTPs are required for translation?

[Babybel56]

They're a supply of energy for protein synthesis aren't they?

[JackBean]

what doesn't? Let's ask the other way - transcription uses RNA as a template?

[Babybel56]

Transcription uses DNA as a template to create an antiparallel strand of RNA. Ah-ha. I misread the points. Okay dokey I would like to retract my answer and replace it with a complete reverse!

ATG codes for methionine (START codon) when part of DNA. So transcribing DNA into RNA would require it to be present. I'm going with b.

[JackBean]

confess, you're doing it just to show the wrong answers, rigth?

Is the start codon required for transcription?

[Babybel56]

Clearly transcription isn't my strong point! You think it doesn't need a start codon?

There are 3 major processes (let's do them on a short sequence):


Replication:

DNA-> DNA

aaaatgccctcctaacta (DNA template)-> ttttacgggaggattgat (DNA product)


Transcription:

DNA ->mRNA

ttttacgggaggattgat (DNA template) -> aaaaugcccuccuaacua (mRNA product)


Translation:

mRNA -> protein

aaaaugcccuccuaacua (mRNA template) -> Met-Pro-Ser (peptide product)

See if you can figure out the right answer by looking at the examples.

[JackBean]

Babybel: no, the START codon is for translation Transcription starts with promoter

[Babybel56]

Ah genetics the source of all that is unholy.
