The most common cause of anemia is iron deficiency.
I thank the answer is true
Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.
The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.
Hence, the correct answer would be option D.
If the number of chromosomes was not reduced before sexual reproduction, any offspring would have too many chromosomes causing genetic defects.
Structurally speaking, RNA and DNA are different. One clear distinction between the two is that RNA is single stranded, while DNA is double stranded. Another way they differ is found in their nitrogen bases. The four bases for DNA are Adenine, Thymine, Cytosine, and Guanine (think, ATCG). The bases for RNA are the same, except Thymine is replaced with Uracil (think, AUCG).
Another note is that RNA polymerase is unable to detect errors in base pairings, unlike DNA polymerase, but their syntheses are both in the 5’3’ direction. Hopefully this helps you answer this question.
