mole. bio. chat :8-10-2005

Sorry,I missed the initial part of the discussion...here is the remaining...

[usmlear] sorry got dc
[Unregistered] answer is no

[usmlear] which poly. forms tRNA?

[Unregistered] its ok go ahead

[Unregistered] 3

[usmlear] rt

[usmlear] name some drugs which can inhibit RNA polym.?

[Unregistered] what is rho factor?

[Unregistered] in eu-amnitin

[Unregistered] in pro-dactinomysin and rifampin

[usmlear] its a protein found in prokaryo.

[usmlear] rt

[Unregistered] what does it do?

[usmlear] termination of Tx

[usmlear] transcription

[Unregistered] rt

[Unregistered] what happens when terminates without it?

[Unregistered] Hair pin loop and poly U

[Unregistered] formation

[usmlear] ok,got it..mutaion?

[usmlear] which type is it?

[Unregistered] no it is rho indipendent termination

[usmlear] rt..also k/as intrinsic termination

[Unregistered] ok

[usmlear] so,in prok. its imp

[Unregistered] ok dint know that

[Unregistered] where does RNA poly fix to start transcription?

niks has left the chat.

[Unregistered] at promoter reigion specifically to TaTAA box

[usmlear] ok

[Unregistered] TATAA box directs RNA poly to start codon

[usmlear] polyA tail at which end..3' or 5'

[usmlear] rt

[Unregistered] 3'

[Unregistered] What is the start codon?

[Unregistered] for all living and non living things for that matter

[usmlear] rt

[usmlear] AUG

[usmlear] GUG

[Unregistered] not GUG

[usmlear] any of these 2 maybe start codon

[Unregistered] IS GUG rt?

[Unregistered] what is wobble effect?

[usmlear] i will check..not sure though

[Unregistered] ok I read its allways for all beings its AUG---Methionin

[usmlear] ok thx

[usmlear] wobble base pair..imp in translation

[Unregistered] yes which base in tRNA

[usmlear] hi erum..u r so silent?

[Unregistered] 3" or 5"

[usmlear] 3

Yousef has left the chat.

[Unregistered] 3' in mRNA but 5' in tNA

[usmlear] ok

[Unregistered] What end does the tRNA bind?

[usmlear] termination of tr. in pro.?

[Unregistered] TTranscription or Translation?

[usmlear] stem & loop +UUUU

[usmlear] ?

[Unregistered] oh ok since we alredy discussed I thought you were askin about termination of translation

[usmlear] what r the steps in translation?

[Unregistered] initiation

[Unregistered] elongation and termination

[Unregistered] what are the termination of trnslation codes?

[usmlear] rt

[usmlear] 3 possible stop codons..

[Unregistered] what are they?

[usmlear] uaa

[usmlear] uag

[usmlear] uga

[Unregistered] you are an elian.. you go away.. and you are gone.. sad isn't it?

[usmlear] yes

[usmlear]

[usmlear] name some drugs which can disrupt this process?

[Unregistered] lindamysin

erum has left the chat.

[usmlear] chloremphenicol,tetracyclin

[Unregistered] erythromysin

[usmlear] anisomycin

[Unregistered] what is the starting Amino acid in ecoli?

[Unregistered] f-methyl methionin

[Unregistered] in eucaryotes-just methionin

[usmlear] rt

[usmlear] my comp. is v. slow today.

[usmlear] site of translation?

[Unregistered] I type slow kinda old

[Unregistered] ribosome a site and p site

[usmlear] transcription in nucleus & translation in cytoplasm

[usmlear] rt

[usmlear] example of silent type of mutation?

[Unregistered] a for t

[Unregistered] and g for c and vise versa

[Unregistered] hey I gotta go now buddy

[usmlear] yes..so they alter codon,but final amino acid remain same?

[Unregistered] nice little hy bits

[usmlear] ok,bye

[usmlear] thx

[Unregistered] welcome

[Unregistered] bye
