Basic structure of DNA or deoxyribonucleic acid: A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-gl...
1. What are the DNA and its role in heredity 2. What are the structure of the DNA, the genetic code, the replication of the genetic material? What is the difference between DNA methylation and histone methylation? What are the major functions of DNA?
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...
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 ...
What is DNA made of? 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)...
Nicotinamide adenine dinucleotide (NAD) is a crucial coenzyme formed by the union of two nucleotides bonded covalently through their phosphate groups. It exists in cells in two forms: NAD+ (oxidized) and NADH (reduced). NAD participates in numerous redox reactions, facilitating the transfer of ele...
nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of sequences. The DNA structure defines the basic genetic makeup of our body. In fact, it defines the genetic makeup of nearly all life on ...
for all known forms of life, alongside proteins, lipids, and complex carbohydrates (polysaccharides). As they are made up of smaller monomeric units called nucleotides, the two DNA strands are called polynucleotides. Each nucleotide is made up of a sugar called deoxyribose, a phosphate group, ...
aThe phosphate group is then transferred to the regular protein(an activator or repressor), which changes shape to its DNA binding form. 磷酸盐小组然后转移到规则蛋白质(活化计或镇压者),改变形状对它的脱氧核糖核酸约束形式。[translate] aelements of wave mechanics 波动力学的元素[translate] ...
What is the role of a phosphate group in a strand of DNA? What is the main function of the DNA polymerase III enzyme? What are the role of DNA polymerase and RNA polymerase? What is the purpose of a primer during DNA replication?
