2017年7月19日 · The above structure is a #color(magenta)"nucleotide"#.. It consists of a: #color(orange)"phosphate group"# #color(red)"5-carbon sugar"#, and

2016年5月26日 · Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA ! - Let us start the story at the level of an eukaryotic diploid cell. There is a nucleus, inside which you see chromosomes in pairs. These are called homologous …

2015年5月14日 · Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are composed of nucleotides. A nucleotide is composed of three smaller molecules; a five-carbon suger, a phosphate group, and a nitrogenous base. A DNA nucleotide contains the five-carbon sugar deoxyribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine …

2018年4月17日 · See Below Nucleotide Monophosphates, NMPs, are nucleosides that have 1 phosphate group. Here is GMP. All simple nucleotides have this phosphoester bond. When one nucleotide makes a linkage with another nucleotide, the phosphate group (which already has 1 ester bond) makes a 2nd ester bond. This becomes a phosphodiester bond. In the picture …

2018年6月6日 · Nucleotides are joined by phosphodiester bonds in a polynucleotide strand. Remember however that hydrogen bonds join the two polynucleotide strands themselves. There are two hydrogen bonds between adenine ( A ) and thymine ( T ) and three between guanine ( G ) and cytosine ( C ). However, this should not be confused with the fact that the polynucleotide …

2015年11月15日 · THREE parts include nitrogen containing base, sugar backbone and phosphate group figure shows adenine structure. nucleotide shown in the figure is divided into nitrogen containing base, sugar backbone and phosphate group

2015年7月2日 · The covalent bond that links nucleotides in the sugar-phosphate backbone is a phosphodiester bond. Nucleotides are linked together by the formation of a phosphodiester bond which is formed between the 3' -OH group of one sugar molecule, and the 5' phosphate group on the adjacent sugar molecule. This results in a loss of a molecule of water, making this a …

DNA replication is a fundamental component of biological beings in which genetic material is copied but the genetic code is preserved. This allows traits to be passed to offspring as well as allows for cell growth and regeneration as life continues.

An isotope is a variant of an element in which it has an equal number or protons but a varied number of neutrons. The notation of an isotope occurs by adding a subscipt and superscript to the left side of an element such as 238 92U (uranium isotope)

2016年11月22日 · Adenine, Ribose, and three Phosphate groups. ATP molecules are used by all living organism as energy to carry out life functions. Also notable, ATP stands for Adenosine Triphosphate. This molecule is composed of three parts: Adenine Ribose Three Phosphate Groups Here is a picture:
