Nucleic acids are the biopolymers, or large biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA . They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
To have two genetically different cells, a cell must undergo sexual reproduction.
The correct answer is option (A) Variation in the strawberry plants.
When the effect of fertilizer on the growth of two strawberry plants is tested, unavoidable source of experimental error is the variation in the strawberry plants. Variation refers to the deviation or differences from the normal plant which can be due to genetic variation. It is due to change in the DNA sequence. If any one of the two plants being tested show variation, the rate of metabolism differs and changes the growth pattern of the plant. The rate of absorption of water and nutrients is effected which brings change in the growth of the plant and causes an error in the experiment and the result.
Answer:
If B is the allele for brown eyes and b is blue, the genotype of the blue-eyed man is bb. His wife must be a Bb heterozygote--she must have a B allele (she has brown eyes), but she must also have inherited a b allele from her blue-eyed mother (whose genotype was bb).
