other question

1.the enzyme RNA polymerase catalyzes the synthesis of specific RNA when provided with which as template

-double-stranded DNA

2.each of the event can occur at synapsis except one.which is exception?

1.rna polymerase makes any type of rna from dna,thus the answer is ds dna!

2.the exception is saltatory conduction as it can occur only at nodes of ranvier!
hope this helps! :thumbup:

Hi,

I think it is conc gradient since in the question they have asked how facilitated diffusion differs from active transport.active transport is against conc gradient.Other choices impies to both facilated diffusion and active transport as well.

OK,SEE,QUESTION SAYS while determining B.P. when is FIRST HEART SOUND HEARD ,,it is only because of WHEN BLOOD FLOW THRU ARTERIES IS TURBULENT
for heart sounds to be heard we dont have to measure b.p,we can simply heard heart sound while keeping stethoscope over the chest to listen 1st and 2nd heart sounds.why will we keep stethoscope on chest while determining blood pressure?????????????to hear first heart sound.???????
i think i cant explain more than this..i feel the answer that way.Hope this helps.

hi celestial,
first of all what is cdna?
its complementary dna,which is single stranded dna formed from mRNA BY enzyme reverse transcriptase so our answer will be (B)

3.epithelial transport

ANS IS OSMOSIS

hi ridge,
why osmosis?
the q states a membrane,not a selectively permeable membrane!and moreover,in osmosis,the fluid moves from a low conc region to high conc region ,not the solute particles!correct me if i'm wrong!

no inder,i was not asking about the 2000 yr q,
the previous q regarding facilitated diffusion having a conc.grad/transport max.!thatz the one i was talking about!these are in year2000
the answer was
1. thrombin
2. facilitated diff

no dent02,u may be right!it is facilitated diffusion,as the q mentioned about non-penetrating solute!i simply overlooked that part![QUOTE=prady]1.simple diffusion
2.thromboxane a2-a platelet aggregrator!

I am wrong for thrombin
but y not facilitated diffusion.
Man !i am very badly prepared.

[QUOTE=prady]hi ridge,
the answer is osmosis only.
osmosis is possible in case of selective permeable membrane only, and only water is allowed to pass thru it.
our second part of question is nonpenetrating solute that is protein,so it can not pass thru selective membrane .
question itself gives clue.
now diffusion and osmosis have in common .osmosisthat move from lowto high conc .and diffusion of protein can be possible by some carrier also,as it is only dependent on gradient and there is no selectivity in memebrane in case of difusion.
hope it helps.

Hi Prady & syk
Just wanted to ask how did u calculate the answer for this one? I know wat syk answered above but in the decks isn't it written that the sum of purines is equal to the sum of the pyrimidines. So if we calculate G on the same strand shudn't the answer be 50 ? Plz explain i m confused.

explain please

1) Methyl xanthines such as caffeine & theophylline enhance lipolysis in adipose tissue by
- inducing adenylate cyclase synthesis
- inducing triglyceride lipase synthesis
- inhibiting cAMP phosphodiesterase activity
- directly activating an intracellular protein kinase
- enhancing the binding of epinephrine to an extracellular membrane receptor

2)Polypeptide hormones generally exert their effect by binding to which of the following?

- intracellular receptors & stimulating protein synthesis
- receptors on cell membrane & stimulating protein synthesis
- intracellular receptors & altering the specific activity of certain enzymes
- receptors on cell membrane & altering the specific activity of certain enzymes.

3) Each of the foll. can be increased by polypeptide hormones except one. Which one is the exception?

- inositol triphosphate conc.
- intracellular calcium conc.
- intracellular potassium conc.
- adenylate cyclase activity
- protein kinase C activity

4) What is the net charge on glutamic acid at a ph of 1?

- +2
- +1
- 0
- -1
- -2


Thanx for helping out. Will highly appreciate if answer is followed with some sort of explanation. Thanx again.

I think its 10%.
Adding up % of A,T,C IS 90%.Remaining should be G on the same strand which gives the % of C on the other strand.
Correct me if am wrong.
It is 10%
A+T=G+C
From this G comes out to be 10%, G will bond with C in other strand,so % of C in other strand is10%

Thanks,

[QUOTE=syk hi
thank you syk for clearing this doubt and i think all this misconception originated in very first few threads and all of us followed the wrong formula to solve this equation.
u r absolutely right that A=T AND G=C AND SO A+G=T+C SO OUR ANSWER IS 50 NOW.
THIS WAS CHARGAFF'S RULE AND THIS TIME I HAVE CHECKED WITH LEHNINGER BOOK.
SO I AM SURE WE HAVE REACHEDTO THE RIGHT ANSWER.
I HAVE DELETED MY EARLIER thread so that no one else can be misguided anymore.
