Question

can someone tell me difference between primary, secondary and tertiary structures of proteins?
( simple answers no copy and paste )

Answer 1

primary: amino acid sequences (hydrogen bonds)
secondary: begins to fold to from beta sheets or alpha helices
tertiary: folded to become a functional protein

Answer 2

and whats the difference between mRna and trna ?

also the processes transcription and translation

Answer 3

triplet base of mRNA form codon, while the triplet base of tRNA form anticodon.
tRNA binds with amino acid, mRNA don't

transcription: to transcribe the necessary genes from DNA into mRNA because DNA can't move out of nucleus, that's why mRNA is called 'messenger RNA'
translation: to change mRNA sequence into amino acid sequence, just like translating one language to another.

Answer 4

The sequence in which the various amino acids are arranged in a polypeptide chain of protein called 1' protein
The polypeptide chain coiled and joined by H bonds and arranged in 3D shape are 2' protein.
and in 3' protein peptide fold many times to form a compact globular shaped structure.

Answer 5

a simple explanation of messanger RNA is that they carry message from dna to ribosomes for the formation of proteins and trna carries amino acids to ribosomes to make a new polypeptide for the protein

Answer 6

thanks a lot guys. I wish i could give all of you medals :/
