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

everyone has a different immune structured in different ways. some antibiotics will not help certain people because of the lack of lipids and enzymes in the hosts blood. this can be fatal because the body has a natural buffer in the blood that the antibiotic can easily damage and kill the host.
