VCE Biology Question Thread

[Biology24123]

Are G-proteins considered to be secondary messengers

[pi]

What a horrible question.

Agreed. But it sorts out those who can apply theory AND logic. If you went out on the street and asked people if needles were around in the 14th century, I'd be very surprised if >10% said they were.

OK, but how is that relevant to biology

Yes they are a form of secondary messengers, though not all secondary messengers are G-Proteins.

Yeah I know there are others. Thanks

Biology is the study of life, is it not? What isn't relevant hahaha

I don't think there's anything to be too upset or cranky about, just accept this one may have out-smarted you and that you will think out of the box for future questions

Maybe you missed what I meant

Keep calm guys; just study hard..

Haha. We get annoyed over bad questions

[paper-back]

In which directions do RNA polymerase and DNA polymerase (3'5'/5'3') travel down DNA?
In which direction is the mRNA threaded through the ribosome?

Care to clarify? I acknowledge it was a bad question, but the correct answer could be sought via some lateral thinking. Any reason for down-voting my last three posts? Just trying to help

Also not sure why you keep deleting your posts, bit odd

[cosine]

In which directions do RNA polymerase and DNA polymerase (3'5'/5'3') travel down DNA?
In which direction is the mRNA threaded through the ribosome?

RNA polymerase attaches to the 3' end of the DNA template strand, thus as it moves along the strand in the 3'-5' direction, it simultaneously synthesises the pre-mRNA transcript in the 5'3 direction.

Not sure about the second one, ill leave it for someone else but not sure this is needed info for Biol, but yet again the exam tends to ask ridiculous questions that are irrelevant

RNA polymerase produces a new strand that grows in the 5' to 3' direction
DNA polymerase produces a new strand that grows in the 5' to 3' direction (but the DNA is read in the 3' to 5' direction)

Do you think people shared needles in the 14th century? It's really a logic question.

What a hilariously cruel question, love it.

RNA polymerase produces a new strand that grows in the 5' to 3' direction
DNA polymerase produces a new strand that grows in the 5' to 3' direction (but the DNA is read in the 3' to 5' direction)

We read left to right, so does DNA pol and RNA pol (i.e. 3' to 5'). That's how I remember it

Will think of that from now on
