Major Groove Vs Minor Groove

Larger is major groove smaller is minor groove major groove occupied by many water molecule than the minor grooves. In particular the minor grooves look very similar across the different types of base pairs whereas the major grooves look very different.

Subtle Atomic Group Discrimination In The Rna Minor Groove Pnas

Grooves are not equal size and opposite to each other.

Major groove vs minor groove. The two grooves of dna a dna has two grooves i e. Therefore proteins that bind dna regardless of the sequence often interact with the minor groove whereas proteins that interact with only specific sequences of dna interact with the major groove. The major and minor grooves direct p p cannot be calculated for first and last two base steps.

The major groove is deep and wide the minor groove is narrow and shallow. The grooves twist around the molecule on opposite sides. The major and minor grooves refined p p cannot be calculated for first and last three base steps.

Major grrove refined. Simple consequences of different geometry of the base pair results grooves. The grooves twist around the molecule on opposite sides.

The major groove occurs where the backbones are far apart the minor groove occurs where they are close together. Specifically the enthalpies of binding to the minor groove are always positive while the enthalpies of binding to the major groove are invariably negative. So i know that the major minor groove arise from the offset pairing of the two strands in the helix.

Dna protein interactions are major essential processes in the cell life transcription activation or repression dna replication and repair. All my textbook tells me is that pitch causes the off set pairing of dna and this gives rise to the major and minor grooves. Proteins bind at the floor of the dna grooves using specific binding.
