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
homozygous organism is one which possess same genes on their chromosome pair for instance C which represent colour blindness it will be present on both the x chromosomes of a female.
A pair of similar chromosomes with the same genes in the same locations is known as homologous chromosomes. These chromosomes carry genetic information from each parent and are involved in the process of genetic recombination during meiosis.
No, the heat of neutralization can vary for different acid-base pairs due to differences in the strength of the acids and bases involved. Stronger acids and bases typically release more heat during neutralization compared to weaker acids and bases.
A DNA molecule may have the same percentage of guanine and cytosine because they bond together through three hydrogen bonds, forming a stable base pair. This complementary pairing ensures that the total percentage of guanine always equals the total percentage of cytosine in a DNA molecule, known as Chargaff's rule.
Base pair complementarity ensures faithful DNA replication. Remember that a base can only pair with a definite pair and not with just about any base therefore this ensures high fidelity of replication. If guanine can only pair with cytosine the same way that adenine can .only pair with thymine then the copying of the DNA will be accurate.
homologous
an acid and a base that are the same except for an H+ -apex
1:2
The ratio of the corresponding sides is the same for each pair.
Not quite.Each pair of corresponding angles must be the same.Each pair of corresponding lengths must be in the same ratio.If the ratio of their lengths is 1:1 then the two prisms are the same or congruent.ANSWER:FALSE
When a acid/base pair with a common anion (salt ion) is meant, then it is called a conjugated pair. When both of them are in the same solution in about equal amounts then they form a buffer solution, so they also can be named as buffering pair.
There is no ratio of the radius of the base cone to the radius of the base of the cylinder. If they are the same and the height of the cones is the same the ratio of the radius of their bases is 1:1 ant the ratio of the heights is 1:1 and the ratio of the volumes (Vcone:Vcyclinder) is (1/3 π r2 h):(πi r2 h) or 1/3
A conjugate acid-base pair differs by the presence or absence of a proton (H+ ion). The acid in the pair donates a proton to become its conjugate base, while the base accepts a proton to become its conjugate acid. They have the same chemical formula, but differ by one proton.
It is given that two triangles are similar. So that the ratio of their corresponding sides are equal. If you draw altitudes from the same vertex to both triangles, then they would divide the original triangles into two triangles which are similar to the originals and to each other. So the altitudes, as sides of the similar triangles, will have the same ratio as any pair of corresponding sides of the original triangles.
Information that you have about one shape can be transferred to the other. For example, the measure of corresponding angles will be the same; the lengths of each pair of corresponding sides will be in the same ratio.

No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.No. Both forces obey an inverse-square law, so the ratio of electric to gravitational force will always be the same, for the same pair of particles - no matter the distance.
