What is the full name for B DNA?
B DNA stands for B-form DNA, which refers to the most common structural form of DNA found in nature.
Why is B-DNA more stable than A-DNA in solution please explain in detail?
Because of the stability of its riboses. In A-DNA there is a 3C- in Endo position which makes the phosphate near the upper phosphate. This produces more repulsion between chains and it could be a reason of why is more unstable A than B. In B-DNA the 3C is in Exo position ( C2 is in ENDO) and is because of that that phosphates are more farther in these conformation, allowing to get more stable interactions between chains. Hope it helps!! Robert Ramirez
DNA vs RNA?
DNA is more stable than RNA. DNA is double-stranded and forms a double helix. RNA is usually single-stranded and folds back on itself to form stem-loop structures. RNA has 2'-OH group that can participate in intramolecular reactions, facilitating hydrolysis.
When one dna molecule replicated the result is two dna molecules what is true of the second dna molecule?
DNA actually has 3 forms. A-DNA, B-DNA, and Z-DNA. B-DNA is the kind you are most familiar with and present in most organisms. A-DNA can be found in dehydrated samples while Z-DNA is rare and mostly synthesized in the lab.
What features highlights the difference between Z-DNA and B- DNA?
Z-DNA has a left-handed helical structure, zigzag shape, and a high GC content, while B-DNA has a right-handed helical structure, a more regular shape, and a lower GC content. Z-DNA is more elongated and thinner compared to the wider and shorter B-DNA.

B DNA stands for B-form DNA, which refers to the most common structural form of DNA found in nature.
What DNA strand is most common?
The most common DNA helix is B-DNA.
Why is DNA called B-DNA?
B-DNA stands for "B-form DNA," which describes the common structural conformation of DNA. The "B" refers to the characteristic helical shape and right-handed twist of the DNA double helix. Different types of DNA, such as A-DNA and Z-DNA, have distinct structural features that distinguish them from B-DNA.
What two forms of DNA did Franklin discover?
Rosalind Franklin discovered two forms of DNA: the A-form and the B-form. The A-form is a dehydrated version of DNA, appearing shorter and more compact, while the B-form is the more common, hydrated form that is typically found in biological systems. Her X-ray diffraction images provided crucial insights into the helical structure of DNA, particularly the dimensions and orientation of the B-form.
How do you differentiate practically between A form B form and Z form of DNA?
you ask yo mama
Why did Franklin concentrate on the A form of DNA?
Rosalind Franklin concentrated on the A form of DNA because it provided clearer and more distinct X-ray diffraction patterns compared to the B form, which was more challenging to analyze due to its less organized structure. The A form is also more stable under certain conditions, allowing Franklin to obtain high-quality images that were crucial for understanding DNA's helical structure. Her work ultimately contributed significantly to the discovery of the DNA double helix.
What is the most common form of DNA found in organisms?
I believe there is only one form of DNA. There are numerous forms of RNA. The least common RNA molecule is tRNA as it is stimulated by the protein synthesis cycle and is only produced at certain times.

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.
Is the magnesium in part B more or less stable than it is in part A?
The magnesium in part B is more stable than in part A because it is in the form of magnesium sulfate (MgSO4), which is a stable compound. In contrast, the magnesium in part A is likely in a more reactive form, such as magnesium metal or magnesium oxide, which can react with air or water.
Which element is most likely to form an anion Cs B Na Ca F?
Fluorine (F) is the most likely to form an anion because it is in Group 17 of the periodic table and readily gains an electron to achieve a stable octet configuration.
DNA vs RNA?
DNA is more stable than RNA. DNA is double-stranded and forms a double helix. RNA is usually single-stranded and folds back on itself to form stem-loop structures. RNA has 2'-OH group that can participate in intramolecular reactions, facilitating hydrolysis.
