Answer:
1. first part Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins or other molecules, it is called gene expression. second part Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide are attached to the nitrogenous bases within another polynucleotide by way of special chemical bonds called hydrogen bonds.
2. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.
3. Non-coding DNA sequences do not code for amino acids. Most non-coding DNA lies between genes on the chromosome and has no known function. Other non-coding DNA, called introns, is found within genes. Some non-coding DNA plays a role in the regulation of gene expression.
Fungi are classified based upon how they reproduce. The rest of the factors do not include anything of their classification.
