A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a ___
joja [24]

Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.

Explanation:

CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.

In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.

The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.

A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.

A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein
