Question

1 Regardless of the different types of genes, a gene is best described as:
a- DNA coding sequence b- RNA coding sequence c- a protein coding sequence
Explain please

Answer 1

c-  a protein coding sequence  

Gene is the functional unit of heredity and  functional unit of Gene is DNA because genes are made up of DNA. In  molecular terms, a gene commonly is defined as the entire nucleic acid sequence that is necessary for the synthesis of a functional polypeptide or a protein.
