Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. One gene makes one protein. It can carry information. They give instructions for a living being to make molecules called proteins. phosphodiester ___ bond is betwen deoxyribose sugars. Genes come in different forms, called alleles. While the terms “DNA” and “genes” may sometimes be used interchangeably, they are in fact not exactly the same. Approximately 20,000 25. Gravity. D. Benzer. DNA present in the gene comprises only 2 percent of the genome. Within a gene, the sequence of bases along a DNA strand defines a messenger RNA sequence, which then defines one or more protein sequences. Are the genes made of DNA? Evolutionists offer two basic mechanisms: Gene Duplication. The two types of chromosomes are the: Autosomes or autosomal chromosomes; Allosomes or allosomal chromosomes ; There are two copies of each autosome (chromosomes 1–22) in both females and males. Bacteria and viruses have DNA too. Powering muscles, defining the body, determining our eye color Protein … What word is used to describe when a gene is not normal is the “instruction” is changed? Speaking in usual terms, genes are responsible for heredity. Also Read: Lac Operon. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
