Answer:
Malformations in frogs can result from various factors, including exposure to environmental pollutants, mutations in certain genes, or changes in the expression of genes that control the development of organs and limbs.
DNA provides the genetic information that controls the structure, function, and regulation of proteins. DNA is transcribed into RNA, which is then translated into proteins. Proteins perform a wide variety of functions in the body, from structural support to catalyzing chemical reactions and regulating gene expression.
The structure of a protein is determined by its amino acid sequence, which is in turn determined by the sequence of DNA that codes for it. Mutations in the DNA sequence can alter the amino acid sequence and therefore the structure and function of the protein.
Furthermore, the expression of genes that control the development of organs and limbs is regulated by a complex network of proteins that interact with DNA to turn genes on or off. Disruptions in this network can lead to abnormal gene expression and malformations in frogs.
In short, DNA provides the instructions for the structure, function, and regulation of proteins, and disruptions in this process can lead to malformations in frogs.
