The bases on a DNA strand do not effect the shape, and they just effect the bases on the DNA strands. If a strand had the base of “G” with an opposite strand of “C” and you switch the “g” base to an “A” base, the opposite “C” base would flip to a “T” base
G matches with c
A matches with t
Answer:
The major characteristic feature of asexual reproduction is the production of clones.Identical offspring with virtually similar DNA.Therefore,this is advantageous to the parasite because, the offspring or progeny produce are similar(clones), to the parent parasites,thus multiple reproduction can occur when a single individual parasites cells divisions.
Explanation:
The correct answer is D Heterozygous
Alleles are different variants of the same gene, located at the same place in the genome, the same locus.
Since we have two copies of all of the genes, one inherited from our father and other inherited from our mothers, we have two copies or alleles of the same gene.
If both of our parents pass us the same allele, the same variant of a gene, we would be Homozygous for that gene.
In the case that our parents pass to us two different alleles, we would be Heterozygous.
Each offspring will receive one allele from each parent, so the cross will be Yy with yy, resulting in four possible offspring: Yy, Yy, yy, and yy. Since Y is dominant to y, there will be two yellow for every four offspring or the ratio of 1/2 (Look up Punnet squares to understand this concept better)
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of some options
1. There are four major macromolecules found in nature; Carbohydrates, proteins, lipids and nucleic acid. The macromolecule that assists with the production of energy for immediate energy and glycogen storage (which is the storage of "energy" in the muscle) is carbohydrates.
2. The foods that should be selected here are food that are rich in carbohydrate. Examples of such food include Rice, cassava, yam and plantain.
3. To test for the presence of carbohydrate in the food sources chosen in (2) above, iodine test can be used. The choice of iodine test is because the food sources mentioned above contains complex carbohydrates. Few drops of a solution of iodine should be added to a sample of the food, if the colour of the iodine on the sample turns blue black, then that confirms the presence of complex carbohydrates in the food.
