Answer:
Stabilize the DNA
Explanation:
DNA is defined as deoxyribonucleic acid comprises of phosphates group, deoxyribose sugar , amino acids base pairs namely adenine, cytosine , ,guanine and thymine.
Increase in temperature denatures the amino acids and proteins which means losing the basic structural unique properties .When it is denatured there is going to be a big difficulty in the use .
The results gotten from the DNA isolation if it isn't kept in an ice bath will be very inaccurate which is one of the main reasons why the DNA has to be put in it for the best result.
Two human examples of multiple-allele<span> genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes. The ABO system in humans is controlled by three </span>alleles, usually referred to as IA, IB, and IO<span> (the "I" stands for isohaemagglutinin).</span>
Answer:
A cell is the structural and functional unit of life which shows characteristic features like reproduction and cell division. The cell multiplication and reproduction serves many purposes to the organism and is mutually inclusive in prokaryotes.
The reproduction and cell multiplication serve many purposes to cell-like:
1. Maintain continuity of species: Reproduction ensures the continuity of the species on earth and should not become extinct.
2. Helps in the survival of organism: reproduction helps in the survival of the organism by transferring its heredity material to the offsprings.
3. Cell growth: the cell division helps in the growth of the organism.
Answer: alternative D.
Explanation: For the DNA to have the double strand structure, it is necessary to copy the sequence of the existing DNA strand in a complementary sequence of nucleotides, forming hydrogen bonds between them. The mRNA also uses this strategy when reading the DNA strand during the transcription, in order for the translation to begin.
Answer:
the uncontrolled growth of cells is known as cancer
