Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which DNA structure provides a set of instructions for a cell to make specific?
A
cell
B
gene
C
nucleus
D
ribosome
Explanation: 

Detailed explanation-1: -These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins.

Detailed explanation-2: -Each DNA sequence that contains instructions to make a protein is known as a gene.

Detailed explanation-3: -The DNA in a gene spells out specific instructions-much like in a cookbook recipe-for making proteins (say: PRO-teens) in the cell. Proteins are the building blocks for everything in your body. Bones and teeth, hair and earlobes, muscles and blood, are all made up of proteins.

Detailed explanation-4: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Detailed explanation-5: -Genes are small sections of DNA within the genome that code for proteins. They contain the instructions for our individual characteristics – like eye and hair colour.
