So there you have it. The DNA in all of your cells is approximately two metres long, except red blood cells which have none and sperm or eggs which only have about one metre. The chromosomes are less in number and they tend to represent about 2 percent of the human genome. The short answer is that an allele is a variant form of a gene. Chromosomes are visible under microscope. Genes: 1. chromosomes. Each chromosome comprised of the gene in which 10,000 times larger double strand of DNA is packed. The colours of someone’s skin or eye are traits, which are controlled by a gene or a set of genes. Spell. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
Difference between dna genes and chromosomes. The difference between these three DNA structures is how much DNA they contain. Genes are composed of DNA sequences while chromosomes are entire DNA strands that are packed tightly together so they can fit into a cell. Difference Between DNA and Genes. A gamete contains half the number of chromosomes than somatic cell. Genes and Alleles are the same thing. Chromosomes are the structure for the gene. The main difference between DNA and chromosome is regarding the role of genes. What is the difference between Gene and Chromosome? DNA is a string of complex molecules called nucleotides. Chromosomes are the structures that carry genes from one cell to another through cell division; thus, they must be replicated via mitosis. Genes also mutate. … Flashcards. The genotype (or genome) is a person’s unique combination of genes or genetic makeup. Each chromosome contains one DNA molecule and each DNA molecule contains several genes or individual strands. Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits.
