DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.
Is a gene DNA or protein?
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
Is thymine more stable than uracil?
Thymine has greater resistance to photochemical mutation, making the genetic message more stable. A rough explanation of why thymine is more protected then uracil, can be found in the article.
Why does thymine make DNA more stable?
DNA uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable. Thymine is protected from oxygen in the nucleus. Outside of the nucleus, thymine is quickly destroyed.
Which is the chemical name for the DNA molecule?
Deoxyribonucleic Acid (DNA) =. DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix.
What makes deoxyribonucleic acid unique to DNA?
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.
Why is DNA the genetic material of all living cells?
DNA, the Genetic Material. DNA, deoxyribonucleic acid, is the genetic material in your cells. It was passed on to you from your parents and determines your characteristics. The discovery that DNA is the genetic material was another important milestone in molecular biology. Is DNA the genetic material of all living cells?
What are the names of the bases in DNA?
So that “deoxyribo” refers to the sugar and the nucleic acid refers to the phosphate and the bases. The bases go by the names of adenine, cytosine, thymine, and guanine, otherwise known as A, C, T, and G. DNA is a remarkably simple structure.
