Question

How do proteins help determine traits?

Answer 1

As a particular attribute, including skin colour or height, it's easy to think about an inherited characteristic. Although, frankly, any set of genes handed on to you from your ancestors can be known as inherited characteristics.

Complete answer:
-Proteins are essential cell components that perform a wide range of tasks: they perform chemical reactions, produce pigments, shape muscles, fur, and nails. Your physical features are formed by the presence or absence of proteins. The colour of the eye, skin and hair both rely on the development or non-production of pigment proteins. A gene that tells the cell how to build a protein creates these proteins.
-The simplistic eye colour can be one of the examples. In this case, the absence of a pigment called melanin, which is a protein, would allow blue eyes to be created, whereas brown eyes are caused by the pigment being created.
-A characteristic is something which distinguishes you. It can be readily detected, like the colour of your blood, or something concealed in your cells, such as the ability to absorb lactose sugar. Since all of our DNA comes from our ancestors, an inherited trait is known to be any trait we have that is decided by DNA. Inheritance speaks about how from one generation to the next certain characteristics are handed on.
-For the dissemination of this material, segments of DNA, called genes, are responsible. Each gene has the instructions for one protein to be made. Many copies of a gene may be present, and these versions are considered alleles. For starters, you will have either a brown allele or a blue allele in the gene for eye colour. Your parents each gave you one allele for every gene that you have.
-All cells contain thousands of genes, but at the same time, not all of them are expressed or turned on. A substance is made when a gene is expressed. The inherited characteristic you see is triggered by this. With skin colour, a pigment is formed when a gene for brown eyes is expressed. The brown eye feature is the outcome.

Note: The knowledge required to produce functional molecules called proteins is found in most genes. (Other molecules that help the cell assemble proteins are formed by a few genes.) Within each cell, the path from gene to protein is complex and closely regulated. It is made up of two main steps: transcription and translation. Transcription and translation, combined, are referred to as gene expression.
