DNA:Deoxyribonucleic acid, a self-replication material present in nearly all living organisms. DNA can be found in every cell of your body and is what carries all your genetic information. You've probably heard that it takes the shape of a double helix (which it does!). RNA:Ribonucleic aci...
(a)(i) List the components of a nucleotide.[1](ii) Explain what is meant by four different nucleotides.[11(b)Suggest why the brief heat treatment separates the two strands of the DNA double helix.[2](c)Suggest why DNA synthesis takes place in opposite directions on the two separated st...
并指出DNA, RNA之间的区别。Answer: 1, DNA, RNA. 2, DNA is a molecule the stores coded information.RNA works in conjunction with DNA to bring about protein synthesis in cells. 3, nucleotide. 4, DNA is double-stranded. RNA is single- stranded; DNA is deoxyribose, RNA is ribose; DNA’s...
The nucleic acids are biomacromolecules that are one of the four major organic molecules found in all living cells. There are two types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Both DNA and RNA are composed of repeating units called nucleotides. Each nucleotide ...
DNA is composed of deoxyribonucleotides. RNA (which is covered in other modules) is composed of ribonucleotides . Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note ...
A Nucleoside consists of a sugar and a base, while a Nucleotide includes a sugar, a base, and one or more phosphate groups. Both are vital in genetic material, but Nucleotides are the building blocks of DNA and RNA.
When a nucleoside gains a single phosphate group, it becomes a nucleotide – specifically, anucleotide monophosphate. The nucleotides in DNA and RNA are such nucleotides. Standing alone, however, nucleotides can accommodate up to three phosphate groups, one of which is bound to the sugar portion ...
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
