Aleksandr [31]

Answer:

The correct answer is - Genotype : 100 heterozygous (TtRr) and

Phenotype: 100% tall pink.

Explanation:

A cross between dwarf red snapdragon (ttRR) and homozygous tall white plant (TTrr) will form gametes tR and Tr. These gametes fuse and form Heterozygous condition for both traits that is TtRr.

TtRr snapdragons will form tall and pink phenotypically as we know T (tall) is dominant over t (dwarf) and heterozygous condition will be tall. But in condition of color Heterozygous form pink flower.

Thus, the genotype of offspring will be TtRr and phenotype will be all tall and pink for better understanding check punnet square.

Nitrogen forms nucleic acids that are part of DNA, as well as amino acids, which help build proteins.
Pepsi [2]

Nitrogen forms NUCLEOTIDES that are part of DNA, as well as amino acids, which help build proteins. Nucleotides are building blocks of DNA.

<h3>Nucleotides and DNA</h3>

Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long strands of building blocks called nucleotides.

In DNA, there are four types of nucleotides that contain different nitrogenous bases: Adenine, Cytosine, Guanine and Thymine.

The nitrogenous bases are composed of nitrogen and they are fundamental to form nucleotides (nucleotides consist of one nitrogenous base, one sugar and one phosphate group).
