What sugar is found in DNA? What is the sugar found in an RNA nucleotide? What sugar distinguishes RNA from DNA? Where is deoxyribonucleic acid found? How did the first scientists label deoxyribonucleic acid? Why is DNA called deoxyribonucleic acid and not ribonucleic acid?
What two molecules make up the sides, or 'backbone,' of the DNA molecule? What is the sugar found in an RNA nucleotide? Which structural component is found in DNA but not in RNA? Who added an extra strand to the structure of DNA?
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 the 5′-carbon (at the top) and the ...
DNA(deoxyribonucleic acid) is the genetic blueprint of all life. Here are the basics of its construction and function.
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...

第二套:Recent Developments in My Hometown Directions: Suppose the university newspaper is inviting submissions from the students for its coming edition on the recent developments in their hometown. You are now to write an essay for submission. You will have 30 minutes to write the essay. You sh...
DNA computing primarily uses synthetic DNA that is custom-made in laboratories. We start by designing DNA and then dividing it into synthesizable pieces called synthons. The synthons are then broken up into single-stranded oligos sequences and synthesized. Then, we assemble the resulting oligos us...
DNA replication steps. There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to ...
When a cell is following its genetic instructions, it copies a portion of the DNA as a gene to change it to an RNA nucleotide. RNA differs from DNA in two distinct ways. The nucleotides in RNA are made of the sugar ribose and are called ribonucleotides. DNA has deoxyribose as its sugar...
