DNA vs Genes vs Chromosomes: An Overview - Cleveland Clinic
2022年5月20日 · What is the relationship and function of DNA, genes and chromosomes? DNA, genes and chromosomes work together to make you who you are. Chromosomes carry DNA in cells. DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique.

What are DNA and Genes? - University of Utah
All humans have the same genes arranged in the same order. And more than 99.9% of our DNA sequence is the same. But the few differences between us (all 1.4 million of them!) are enough to make each one of us unique. On average, a human gene will have 1-3 bases that differ from person to person.
AN INTRODUCTION TO DNA, RNA, GENES AND CHROMOSOMES. RNA RNA, like DNA, is made up of chains of bases. For RNA these are adenine, guanine, cytosine and uracil (its alphabet is A, C, G, U). Unlike DNA, RNA has one chain of bases (called a single strand). RNA is involved in the protein making process, which has three key steps: 1.
