Explanation:
We have a case of incomplete dominance (purple is an intermediate heterozygous phenotype in radishes)
Parental genotype => RR x WW
F1 genotypic ratio => RR:RW:WW = 1:2:1
F1 phenotypic ratio
=> Red : Purple : White = 1:2:1.

Answer:
DNA contains genes that can be read to create <u>messenger RNA</u> that directs the <u>ribosome</u> to build certain <u>proteins</u> as needed by specific cells or situations.
Explanation:
DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.
Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.
<em>When a </em><u><em>cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized</em></u><em>.</em>
<h2>Answer:</h2>
Uracil
<h2>
Explanation:</h2>
Uracil is the nitrogenous base that is found in RNA but not present in DNA.
Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).
