Intestinal glands ( crypts of leiberkuhn )
Gastric glands ( oxyntic cells and cheif cells)

this can be memorised as Go In Puraani Sabji mandi In Goa..

ciliated columnar epithelium

Respiratory tract
Auditory canal
Fallopian ducts

this one may be known to many but still is very important to mention here
Some say money matters but my brother says big books matter more.

where S=sensory
M= motor
B= both/ mixed

this is for remembering the function of cranial nerves

many of us remain confused about the types of blotting..
i mean which blotting technique is used for what...

southern blotting is used for DNA analysis
Northern blotting is used for RNA analysis
Western blotting is used for proteins

an easy way to memorise this...
south matlab Dakshin... DNA..

west matlab paschim ( or purab.. i'm awful with directions anyways...).. Protein..

aur bacha hai north our RNA.. so thats the only other match...

stop codons are
UAA , UGA, UAG,
now.. it is very easy to remember..
but there may be students like me who forget it a wek after memorising this piece of information..

so, here it is..
UAA - ullu aaya aaya
UGA - ullu gaya aaya
UAG - ullu aaya gaya..

another one..
catadromous and anadromous migration..

catadromous - fresh water to marine water
anadromous - marine to fresh water..

one simple way..
we are freshwater ... if someone comes to our house, we say..
ana , ana ... ie marine habitait to fresh water is anadromous..

when someone goes.. we say.. tata - catadromous.. i.e if an organism leaves freshwater and enters marine - catadromous...

tere cricket area me corn kyon ug raha hai.

tere - thyroid
cricket - cricoid
area - arytenoid
corn - corniculate
kyon - cuneiform
and the last one is epiglottis.. u have to remeber that..
a good thing is that the initial sounds are same...it makes this easier..

one scientist Raunkiaer differentiated plants into 5 life forms...
it is also somewhat tough to remember...
so, another nasty mnemonic for this..

Pehle Chemistry Hame Correctly Teach karo..

Phanerophytes - above 10cm from ground level
Chemaephytes - below 10cm from ground level
Hemicryptophytes - occur at ground level ( eg rosette plants)
Cryptophytes - occur below ground level - eg rhizome etc
Therophytes - perennate in form of seeds...

In DNA duplex
1. template strand,minus strand, sense strand -----> 3'-5'
2. nontemplate strand, plus strand, antisense and coding strand--> 5'-3'
to remember 3-5= -2 so minus strand(remember other names)
5-3= +2 so plus strand

hello guyz... i have come out with some new and very needed ones...

here....

first is the electron transport chain during photosynthesis...

there is one Z- scheme and one cyclic pathway... cyclic pathway is the main one and is most important as Z-scheme is just an extension of cyclic pathway...

so here it is..

plastoquinone(PQ) ----> reduced plastoquinone(PQH2)-----> FeS ---> cytochrome f (cyt-f) ---> plastocyanin (PC) -----> P-700---> FeS --> Ferradoxin (FD)------> cytochrome b (cyt b) ---> again PQ...

now... this can be memorised as ... Parrot Pocketed fully filled plastic cans 700 to Fill its Food breaking site

breaking site = cyt b

food = Ferradoxin

Plastic can = plastocyanin
