Protein structure

Hi guys, I know that Protein structure related to their function. Certain protein usually have alpha helix is more prominent but certain protein have beta structure more prominent. My question is which amino acid is favourable to form alpha helix and beta structure? What function unique to alpha hel...

effects of transgenic plants

Hi all,
What is difference between control weeds by transgenic plants, chemical herbicide and bioherbicide? Chemical herbicide control weed through spray chemicals but how transgenic plants control weeds? I need our suggestion and share your idea.

control weeds

Hi all, How to control weeds? I have some idea. I like to share with all. All of us give our opinion as soon as possible In ancient times,we had used some methods like panchakavya, organic manure to control weeds. Now our technology is well propped. Is any technique identify chemical compounds in pa...

how predict which aminoacid form secondary structure

hi all
How do predict what types of secondary structure (left alpha helices, right alpha helices, parallel beta sheet, anti parallel beta sheet) from amino acid sequence?

Find number of restriction fragment size in chromosome

Hi all, I am prepare in entrance exam. I need help. A restriction endonuclease has the recognition sequence G/AATTC, where "/" indicate the cut side. This sequence is found, on average, once every 'X' residues in a chromosome. 'X' = Options a. 146 base - pairs b. 200 base - pairs c 256 bas...

Re: sequencing

hi to all,
Thanks. I know steps in each DNA sequencing method. I need to know how much size of DNA these method can be read?


"Like the automated sequencing method is only accurate for sequences up to a maximum of about 700-800 base-pairs in length"

sequencing

hi friends,
I know some of methods for Sanger dna sequencing, maxam gilbert sequencing, pyrosequencing, automated dna sequencing which are used for dna sequencing. But I don't know how for these method sequences dna?

gene expression - regulatory sequence

hai everybody, I have some doubt about regulatory sequence in gene expression. Regulatory sequence regulate expression of protein. Is this regulatory sequence is vary from every gene expression or common. I know that in prokaryotic transcription, promoter have consensus sequence (TTGACA) is common t...

Autosome dominant

Is any one explain about "autosomal dominant" and Huntington disease has autosomal dominant. How do transmission from one generation to another generation? Is any crossover happen in meiosis?
