What is base pairing and how is it involved in DNA replication?
Hydrogen bonds, because when replication is completed, each new DNA molecule consists of one new nucleotide chain joinged by hydrogen bonds to a nucleotide chain from the original DNA molecule. Purines and pyrimidines are joined by hydrogen bonds too. The covalent bonds are found in the sugar-phosphate backbones, which are the same through out DNA molecules.
Number of purine bases in DNA molecule with nine base pairs?
4 A pyrimidine always pairs with a purine, so half of the bases will be pyrimidines and half will be purines.
Why all organism have same ratio of base pair in DNA?
Organisms normally have equal amounts of the bases adenine and thymine (ratio of A:T = 1) and equal amounts of the bases cytosine and guanine (ratio C:G = 1). The reason is that there is specific base pairing ie adenine can only pair with thymine and cytosine can only pair with guanine. So in a DNA double helix, every adenine in one strand must be paired with a thymine in the other strand. Similarly, every cytosine in one strand must be paired with a guanine in the other strand. Each base pair consists of a purine and a pyrimidine. Adenine and guanine are purines and thymine and cytosine are pyrimidines. This relationship between purines and pyrimidines was discovered by Erwin Chargaff in the 1950's. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/Chargaff%27s_rules
In coordination only equal language parts may be joined together.?
true
Why are there always the same number of adenine and thymine in a molecule?
Chemical analysis has shown that the number of adenine molecules in a sample of DNA is always the same as the number of thymine molecules. A sample of RNA would show that there are equal numbers of adenine molecules and uracil molecules.
How much tension if the bag is supported by 7 vertical strands That is how much tension is exerted in each strand Answer in units of N?
Assuming that all strands are vertical/ parallel to gravity and equally spaced (on a radius) around the centre of gravity then tension on each strand will be equivalent to weight x 9.81 divided by 7 equals tension in Newtons. If the strands are not normal and/or at varying distances from centre of gravity then it becomes a little more complicated. Summ of tension on strands must equal weight of bag. Tension on each strand is a ratio of it's distance from the COG of the furthest most strand. Don't forget the further from perpendicular a strand is the more tension on the strand.
What is osb board?
OSB stands for oriented strand board. It is made of wood strands and waterproof adhesives. The strength of OSB board is equal to that of plywood.
Are 2 strands of double knitting equal to 1 of chunky?
Usually yes. The best way to test it is to take a ruler and wrap the two strands together around the ruler continuously for one inch length (make sure the yard does not overlap, nor leave gaps). Then take a strand of chunky yarn and do the same. You should get the same number of rotations around the ruler for each. You may also want to note that using two yarns together of different colors will give you a nice heathered effect in the finished product.
Is the amount of cytosine in both strands of a DNA equal?
Since A binds with T and C binds with G, the amount of cytosine would be greater on one strand and guanine greater on the other because the binding is complimentary.
Who to work out the mechanical advantage of a multiple pulleys?
If there are 4 strands holding up the load then the tension in each strand is 1/4 of the load. When the load is raised 1 cm the work done must be achieved by pulling the end by 4 cm because of the reduced force required, but the energy must be the same. Therefore the mechanical advantage is equal to the number of strands supporting the load.
Explain how DNA replication takes place?
An enzyme unzips a DNA stand and a separate strand without base pairs come sup and matches it with the proper ones (A-U)( C-G) making RNA which goes to a ribosome outside the nucleus, makes a protein, makes a new strand of DNA and the other strand re zips with the new DNA strand.
What is fiberglass?
Fiberglass is a composite material reinforcement. Parts made using fiberglass are typically still referred to as "fiberglass." Fiberglass parts are made from strands of glass fiber which are suspended in a polymer (plastic) matrix (resin). Fiberglass cloth is a fabric comprised of strands of glass fibers that are bundled together in different weaves. Unlike carbon fiber, fiberglass can be purchased in the form of cloth where long continuous stands of glass are woven into a fabric using a predetermined weave, or in chopped strand mat where short strands of glass are formed randomly into a fabric and held together by a weak styrene styrene bonding agent. Fiberglass cloth has good direction strength while fibergas mat has a lower strenght but is equal in all directions. The two most common glass types are E-glass and S-glass. S-glass is a higher strength glass reinforcement, sometimes referred to as structural-glass, and as you can imagine it is a bit more expensive.

What i s the basis of chagraff's rule?
Chargaff's rule states that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine. This is because adenine forms complementary base pairs with thymine and cytosine with guanine, ensuring that DNA strands can bind together correctly.
How do you make spandex?
Spandex is a synthetic fiber. It is typically made through one of four processes including melt extrusion, reaction spinning, solution dry spinning, and solution wet spinning. Most of the spandex produced is done so using the solution dry spinning method. In the dry spinning method, a macro glycol with a diisocyanate monomer to produce a prepolymer. The prepolymer is then reacted with an equal amount of diamine. The resulting solution is then cured into fibers and forced through a spinneret. Once the solution is passed through the spinneret, it forms strands of liquid polymer which is heated in the presence of nitrogen and a liquid solvent. This forms strands of solid fiber which are bundled together to a desired thickness. The strands are then treated with a finishing agent. For clothing, spandex is often mixed with either cotton or polyester.
Why are there equal amounts of A and T and C and G in DNA?
There are equal amounts of each base because Guanine binds to cytidine, and Thymidine binds to Adenine. Purines bind to pyrimidines. That is why when you have a certain amount of Guanine nucleotides, then you will certainly have that same amount of Cytidine nucleotides. Same thing goes for A-T base pairs. The only thing that is a little different is the amount of G-C base pairs relative to the A-T percentage. The human Genome is roughly 60% GC rich while the other 40% is AT
What two numbers multiply together to equal 15 and add together to equal 2?
17
Why single stranded RNA does not obey Chargaff's rule?
Because the number of A doesn't not T and G does not equal C. It isn't double strands so it does not have to equal each other.
