Answer: In biology, a gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. Genes and DNA are different..... DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
Hope this helps..... Stay safe and have a great day/night!!! :D
Amino acids are the building blocks of proteins

Answer:
No, Presence of different alleles for an X-linked gene is required to test the Lyon hypothesis.
Explanation:
According to the Lyon hypothesis, to compensate the dosage of X linked genes in males and females of mammals, one X chromosome in all the cells of a female mammal is inactivated and the presence of the gene on the other X chromosome is expressed.
Inactivation of the X chromosome is a random process, that is, either maternal or paternal X chromosome may be inactivated during early embryological development in females.
To test the Lyon hypothesis, the expression of alternative alleles of an X-linked gene in the cells of a female mammal is studied. Given that the human female is homozygous for an X-linked gene, all of her cells would express the same allele for the gene, and the Lyon hypothesis can not be tested.
