well, it's quite useful when enzymes supposed to do something with DNA are searching for the "starting sequence". in major groove, you can always recognize the base pairs without unwinding the double-helix. it's coded by order of the groups CH3, H-bond donor, H-bond acceptor and H, which is different for each combination of base pairs. (you obviously must know the 5´-> 3´ ordering either.) grooves are usefull to be recognized with lot of DNA - protein links structures, like helix-turn-helix pattern, or zinc fingers, which are bonding to the grooves.

What do the structures labeled with the letters represent?
the tertiary structure of DNA include A- B- Z form which differ from each other in geometric according to bases sequences of DNA and condition DNA present in Form A :right handed double helix Most RNA present in this form Major conformation of RNA the most favorable conformation at low concentration of water Bases are displaced away from the axis Major groove is narrow while minor groove is wide Over all shape short and wide Form B : Right handed double helix the most common type of DNA Major conformation of DNA the most favorable conformation at high concentration of water Bases are perpendicular to the axis Major groove is wide while minor groove is narrow Over all shape is long and narrow Form z : Left handed double helix Zigzag form Minor conformation of DNA the most favorable conformation at high concentration of salt Bases are perpendicular to the axis Both major and minor groove are narrow Over all shape is elongate and narrow
What does the latissimus dorsi insert to?
on the intertubercular groove of the humerus just lateral to pectoralis major
What is the shape of DNA?
Though shaped like a spiral ladder it consists of two helical polymers if it was to be unwound. On the outside of the ladder is phosphate and sugars, and in the middle are the bases associated in pairs, one base coming from one helical strand and one from the opposite helical strand.
What is the natural minor scale parallel to g major?
The natural minor scale parallel to G major is E natural minor. This means it has the same key signature (one sharp, F#) as G major, but starts and ends on the note E.
What is the difference between Z-DNA and B-DNA?
Z-DNA is usually found in areas with alternating purine and pyrimidine bases (ie. -ATATAT- ). When you look at it from the side, Z-DNA zig-zags toward the top left of the page/screen (This is essentially what it means when you read "left-handed helical form"), compared to B-DNA ("right-handed") which spins toward the top right. If you look at the top looking down the center of the molecule, B-DNA has no hole in the center (like in A-DNA) and is arranged with the bases in the middle, then the sugar, and then finally the phosphate backbone is at the edges. Z-DNA also lacks a hole in the center, but due to the zig-zagging structure, there is no definite area to locate the bases, sugar, and phosphate backbone -- they are all jumbled up together.
Why DNA has 2 different sizes grooves?
As the DNA strands wind around each other, they leave gaps between each set of phosphate backbones, revealing the sides of the bases inside. There are two of these grooves twisting around the surface of the double helix: one groove, the major groove, is 22 Ã… wide and the other, the minor groove, is 12 Ã… wide. The narrowness of the minor groove means that the edges of the bases are more accessible in the major groove. As a result, proteins like that can bind to specific sequences in double-stranded DNA usually make contacts to the sides of the bases exposed in the major groove. This situation varies in unusual conformations of DNA within the cell , but the major and minor grooves are always named to reflect the differences in size that would be seen if the DNA is twisted back into the ordinary B form.
What is major groove in DNA?
The major groove is a larger space between the two strands of the DNA double helix where the nitrogenous bases are more accessible for interactions with proteins or other molecules. It plays a role in the binding of transcription factors and other proteins involved in gene regulation.
How many bases are found in one turn of the DNA double helix model?
There are typically 10 bases found in one turn of the DNA double helix model. This gives DNA its characteristic twisted ladder shape and allows for the base pairing between adenine and thymine, and cytosine and guanine.

What is aDNA?
A-DNA is a conformation of DNA that differs from the common one (B-DNA) by: - a wider right-handed spiral - a shallow, wide minor groove - a narrower, deeper major groove. The A form occurs under non-physiological conditions in partially dehydrated samples of DNA, while in the cell it may be produced in hybrid pairings of DNA and RNA strands
What part of CAP and lac repressor are directly responsible for recongnition of specific DNA sequences in the major groove?
A protein that has a helix-turn-heloix domain can bind to DNA because one of the helices interacts with the sugar phosphate backbone of a DNA strand while the other helix binds to the base bairs in the major groove. The section of the helix-turn-helix motif that binds inside the major groove is called the "recognition sequence"
What muscles are attached to the lateral side of the bicipital groove?
To the best of my knowledge, three muscles attach to the bicipital groove of the Humerus: The Latissimus Dorsi, the Pectoralis Major and the Teres major. Marcel Fromond NMT Student
Why do DNA strands have an asymmetrical structure?
DNA strands have an asymmetrical structure because of the specific pairing of nucleotide bases (A-T and G-C) in the double helix. This complementary base pairing results in two antiparallel strands that run in opposite directions, creating a helical structure with a major and minor groove. This asymmetry is essential for DNA replication and transcription processes.
What are all the piano chords?

What is the relative of c major to a minor?
