Question

part b
once a protein is formed, how does that protein become an observable trait?
proteins cause changes in the optic nerve of the eye, leading to observable characteristics.
proteins create dna base sequences, which are the instructions for traits we can observe like colors.
proteins are created from rna and form observable traits when intricately linking to form polypeptides.
proteins perform tasks such as chemical reactions, making pigments, forming muscles, etc.

Explanation:

Proteins are essential molecules in living organisms. They are synthesized through a process involving DNA and RNA. DNA contains the genetic information (base sequences) that serves as instructions for making proteins. RNA (messenger RNA - mRNA) is transcribed from DNA. Then, during translation, ribosomes use the mRNA sequence to assemble amino acids into polypeptides (which fold into functional proteins). Proteins perform various tasks such as catalyzing chemical reactions (as enzymes), forming structures (like pigments in the eye, muscle proteins), etc. When proteins are involved in processes like affecting the optic nerve (e.g., in eye - related traits), their specific functions (due to their structure determined by amino acid sequence) lead to observable characteristics. For example, proteins in the eye's photoreceptor cells or those involved in nerve signal transmission in the optic nerve can influence traits like eye color, visual acuity (an observable trait).

Answer:

Proteins perform tasks such as chemical reactions, making pigments, forming muscles, etc.
