Answer:
The answer is true.
Explanation:
True breeding for purple and white means that they are homozygous for that phenotype, for example AA is genotype for purple, while aa is genotype for white. Aa is heterozygous and it represents incomplete dominance phenotype. If we cross true breeding for purple and white:
P: AA x aa
F1: Aa Aa Aa Aa (all of them are with incomplete dominance color)
F2 (Aa x Aa): AA Aa Aa aa (1/4 1/2 1/4)
Answer:
deoxyribonucleotides consist of a nitrogenous base and a pentose sugar with the nitrogenous bases covalently bonded to make the primary structure
Explanation:
A deoxyribonucleotide is a nucleotide that consists of a nitrogenous base (i.e., purine or pyrimidine) that binds to deoxyribose (i.e., a pentose sugar-containing five carbon atoms), and one phosphate group attached to the nitrogenous base. In the DNA, there are four types of nitrogenous bases: two purines (Adenine and Guanine), and two pyrimidines (Cytosine and Thymine). All these bases are attached to 1' carbon (C1') of deoxyribose by a glycosidic bond. A nucleoside is a nitrogenous base linked to ribose (in RNA) or deoxyribose (in DNA).
