chipotle said:
I thought the answer was B ..as ascending loop is not permeable to water ...can u please explain as to why its c ..thanks !
Click to expand...


ascending loop is impermeable to water so nacl is reabsorbed without water. as a result tubular fluid [na] and tubular fluid osmolarity is decreased to less than their concentration in plasma. this segment is called diluting segment.


i hope this will help.
do u have the answer?

1. wHICH OF the following eukaryotic DNA control sequences doesnt need to be ina fixed loaction and is most responsible for high rates of transcriptiion of particular genes?

2. Reverse transcriptase, differs from DNA Polymerase in which of the following?

a. synthesis DNA in 5' to 3' direction
b. contains 3' to 5' exonuclease activity -answer (rt has no proof reading ability => no exonuclease)
c. follows watson and crick base pair rules
d. synthesises dna in 3' to 5' directio
e. can insert inosine into a growing dna

3.Primase is nt required during dna repair process bcz:
a. all of the primase is associated wid replication origins - 80% dis is correct
b. rna wud be highly mutagenic at repair site
c. dna polmerase 1 doesnt need a primer
d. dna polymerase 3 doesnt require a primer
e. dna polymerase 1/ 3 can use 3'-OH for elongation

4. The key mechanistic failure in pt. wid xeroderma pigmentosa:
a. mutation in primase gene
b. inability to excise a section of UV damaged dna --correct
c. mutation of one of d mismatch repair component
d. inability to synthesize dna across damaged region
e. loss of proof reading capacity

not sure.
enhancer stimulates the transcription and can be located thousands of base pairs up or downstream from the start site. so i think ths is the answer.

Cartilage model is first developed during the ossification. but note that after ossification is complete the cartilage is not present anymore and is not a part of the osteon.

A. Vertical
B. Mesial and Lingual
C. Mesial and Facial
D. Distal and Facial
E. Distal and Lingual

hydroxxy proline though doesnt have a codon is incorporated in to proteins how? the collagen triple helix <<< refer to collagen here

difficulty in swallowing which space infected after 3 molar extraction >>submandibular space. (swelling in the submandibular region may extend to the anterior cervical triangle to the clavicle and if parapharyngeal space is involved,may cause respiratory obstruction) .

What structures make up the bronchopulmonary segment? -
Tertiary bronchus
Bronchial artery
Pulmonary artery

streptococcus gene transfer is what mechanism>>> Transformation......

@krasnodar, ddimps, firasoblast and kash ...u mean the most common systemic fungal disease would be blastomycoses ??

Common sites of artherosclerosis
1. large blood vessels- aorta, carotid A and iliac
2. medium blood vessels- coronary, cerebral, limbs
3. small BV and veins- Never affected
So the commonest of all would be the carotid artery

Read this link regarding the CD4- CD8 cells
ans would be decr-no change
http://www.thewellproject.org/en_US...ngs_First/Understanding_CD4_and_CD8_Cells.jsp

Drum- medial wall of middle ear

Palatal root of max 2nd molar would have a Distolingual inclination.

please correct me if am wrong.

Hi chipotle,

I think if the question says common systemic fungal disease - it should be Blastomycosis because Athlete's foot cannot be systemic...

Pls correct me if i am wrong...
