The twisty columns of the double helix are phosphate and sugar(deoxyribose), which are bonded by a covalent bond. Each nucleotide consists of one of each, and also a nitrogen base. The rungs are nitrogen bases, each nucleotide has one base, and one side of the ladder bonds to the other side of the ladder through hydrogen bonding of complementary base pairs. The base pairs of DNA are A-T and C-G
Answer:
Purebred can be described as organisms that result from true-breeding. True breeding occurs parents who have a homozygous genotype are crossed so that the offspring produced might be similar to them. The alleles of the desired genes will be the same in the parents which will breed and produce similar alleles in their offsprings.
However, the phenomenon of pure breeding limits the gene pool and genetic variety becomes limited by such methods.
Answer:
The correct answer is - XDXd and XD Y
Explanation:
Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-
in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.
So the correct genotype would be
mother: XDXd ( a carrier woman)
father : XDY (normal man)
The velocity of the object is similar to speed but has one main difference: velocity takes into account the direction of an object. Since speed does not take direction into consideration, it is considered to be a scalar quantity. Thus, the speed of an object can never be negative.
