Concept explainers

Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, d…

DNA as the Genetic Material

DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it a…

Genetics

The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents …

DNA Replication

The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.

Students have asked these similar questions

Watson and Crick used scientific reasoning, their knowledge of biochemistry, and the research of other scientists to make one of the most important scientific claims of their time: DNA is a double helix with strands running in opposite directions. Between these strands, A pairs with T, and C pairs with G.

While trying to determine the structure of DNA, Watson and Crick at one point proposed that like bases are bonded to like bases. For example, thymine would be bonded to thymine, cytosine would be bonded to cytosine, and so on. Explain why this proposed model would not fit based on what was discovered to be true about DNA.

How did Griffiths and Avery discover that DNA was the molecule of heredity? Would we have been able to discover the structure of DNA without this work? Why or why not? Would we have been able to understand or actually try to understand DNA replication without his work? Why or why not?
