what are 3D base pairs ?
Answer / biomaster
Each DNA molecule is made up of two spirally coiled chains
made up of sugars and phosphorus molecules and in the
middle nitrogenbases.This arrangement looks like a ladder.
nitrogen bases are adenine, guanine, thiamine, cytosine.
Adenine always pairs with thiamine by two hydrogen bonds.
These are known as 2D base pairs.
Guanine always pairs with cytosine by three hydrogen
bonds.These are known as 3D base pairs.

A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll. If a tobacco plant heterozygous for albinism is allowed to self-pollinate and 500 seeds germinate: a)how many offspring will be the same genotype as the parent? b)how many seedlings would you expect to be white?
what causes heterosexuality?
what is Homosexual Gene?
In horses coat color is dependent upon genes as follows: A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb in liver. In addition, palimino is derived by Dd with chestnut. A palimono stallion (DdAAbb) is crossed with a palimino mare (DdAAbb). What percent of the offspring will be palimino?
Are dominant genes related to dominant traits?
In hogs a gene that produces a white belt around the animal's body is dominant over its allele for a uniform body. Another independent dominant gene produces fusion of the hoof (syndactyly). Suppose a uniformly colored hog homozygous for syndactyly is mated with a normal footed hog homozygous for the belted character. What would be the phenotype of the F1? If the F1's interbreed, what would be the phenotypic ratio of the F2?
Is Genetic Engineering worth the cost and effort?
Among the population size of 500, 50 of 150 heterozygous individuals showing polydoctily. Then what is the penetrance of that population
Is Genetic engineering the best of solution?
The rare trait of ocular albinism (almost complete absence of eye pigment) is inherited as a sex-linked recessive. A man with ocular albinism marries a woman who neither has this trait nor is a carrier. What would you predict about their offspring concerning this trait?
Suppose a father of blood type B and a mother of blood type O have a child of type O. What are the chances that their next child will be blood type O? Type B? Type A? Type AB?
what is the approximate number of genes in the human being according to human genome project?
