What types of bonds form between the complimentary base pairs?
DNA is a double-stranded molecule twisted into a helix (think of a spiral staircase). Each spiraling strand, comprised of a sugar-phosphate backbone and attached bases, is connected to a complementary strand by non-covalent hydrogen bonding between paired bases. The bases are adenine (A), thymine (T), cytosine (C) and guanine (G) so pretty much complementary bases are connected by a hydrogen bonding.
What is the role of sugar phosphate in DNA?
As the phosphate group has a negative repulsion due to the negative charge on oxygen it cause the DNA to bent to the double helix "spiral" structure as we know it - by Matouš Janda
Why do scientists use composition books instead of spiral notebooks?
They wanna look profesional
What is a protein channel made of?
An ion is an atom of any element, or a molecule of any compound, in which the number of positive charges (protons) and the number of negative charges (electrons) are not equal. Hence the ion is an atom or molecule with a net charge.
Is it possible to combine process models If so, provide an example?
Yes, it is possible to combine the software process models. Some possibilities to combine software process models are given below: Evolutionary process model. Incremental process model. The spiral model.
What shape does a DNA Molecule have?
DNA molecule is shaped like a spiral staircase and is composed of two parallel strands of linked subunits.
When unwound a double helix looks like what?
The coiled structure of double-stranded DNA in which strands linked by hydrogen bonds form a spiral configuration, with the two strands oriented in opposite directions.
The spiral staircase structure characteristic of the DNA molecule?
Double helix
Is it harder to build a spiral staircase or a straight staircase?
It is harder to build a spiral Staircase because if you build a spiral staircase it will be longer and twistier than a straight staircase.
What type pf simple machine is a spiral staircase?
A spiral staircase is a type of screw. A spiral staircase is a type of screw.A spiral staircase is a screw. So it is an inclined plane.
What is the Sims 2 double deluxe spiral stairs cheat?
There is no cheat. The spiral staircase is an buildmode object that was intergrated within the apartment life expansion pack. So unless you have that exansion, you are not getting a spiral staircase.
What is the moleculer shape of dna?
DNA molecule is shaped like a spiral staircase and is composed of two parallel strands of linked subunits.
When was the first spiral staircase created?
The first spiral staircase is mentioned in the Solomon's Bible. Therefore one can say that the first spiral staircase was created around 3000 years ago. The spiral staircase is the same as 'winding stairs'.
What is the official name of the shape DNA is found in?
A double helix, like the sides of a spiral staircase.
