DNA molecules are polymers and are made up of many smaller molecules called nucleotides.

. 3 pts Describe in detail the protein structure of DNA polymerase I. This structure was discovered by Watson and Crick. Remember that the phosphate and sugar molecules are the backbones of the ladder.

In terms of structure DNA polymerase I is a single polypeptide chain that is com posed of 928 amino acids with 109 kDa molecular weight. STRUCTURE OF DNA These units are linked by 3 to 5 phosphodiester bonds to form a long polypeptide chain. Describe in detail the structure of DNA polynucleotide chain.

The purines and pyrimidines. Model of DNA molecule. Describe the double helix structure the bonds the bases etc.

At five levels of complexity DNA has nucleotides and a strand and double helix and a genome. The two-sided ladder formation of the double-helix DNA structure. The DNA molecule consists of 4 nitrogen bases namely adenine A thymine T cytosine C and Guanine G which ultimately forms the structure of a nucleotide.

A nucleotide has three components a nitrogenous base a pentose sugar deoxyribose and a phosphate group. The two strands of DNA run in opposite directions. 3 pts Describe in.

A molecule of DNA consists of two strands that form a double helix structure. Hydrogen bonds between the base portions of the nucleotides hold the two chains together. The sugar-phosphate chain is called the DNA backbone and it is constant throughout the entire DNA molecule.

A DNA Molecule Consists of Two Complementary Chains of Nucleotides. Watson and Crick describe structure of DNA 1953 Photo. 1 Answer to Explain in detail the structure of DNA.

DNA molecules arrange themselves in a model called the DNA double helix. Each nucleotide is composed of a nitrogenous base a five-carbon sugar deoxyribose and a phosphate. Describe in detail the chemical structure of DNA how DNA is replicated and the experiment by Meselson and Stahl that determined the method of DNA replication.

Each of the two strands is a long sequence of nucleotides or individual units made of. In the late nineteenth century a German biochemist found the nucleic acids long-chain polymers of nucleotides were. A molecule of DNA is a bunch of nucleotide monomers joined one after another into a very long chain.

Its structure is described as a double-stranded helix held together by. DNA is a double helical structure consisting of two long strands coiled around a ventral axis. The most commonly occurring pyrimidines in DNA are cytosine and thymine.

DNA is a two-stranded molecule that appears twisted giving it a unique shape referred to as the double helix. The third complexity of DNA. Each nucleotide contains a phosphate group a sugar molecule and a nitrogenous base.

Its a 3-D structure that is stored in the nucleus of all cells. There are two types of nitrogenous bases Purines Adenine and Guanine and Pyrimidines Cytosine and Thymine. It also has three sites that provide three different catalytic activities which includes 3 to 5 exonuclease 5 to 3.

The A and G are purines and the C and T are pyrimidines. Each strand is a polynucleotide chain composed of many nucleotides. Use the description of a ladder.

The 3-hydroxyl of one sugar is linked to the 5-hydroxyl of another sugar through a phosphate group Fig. The double helix looks like a twisted ladderthe rungs of the ladder are composed of pairs of nitrogenous bases base pairs and the sides of the ladder are made up of. Describe in detail the structure of a DNA molecule including the basic building blocks and how they are arranged.

A C T G. DNA deoxyribonucleic acid and RNA ribonucleic acid are composed of two different classes of nitrogen-containing bases. Double helix Two strands of DNA hydrogen-bond with each other form a.

The bases A G C G form the rungs of the ladder. A single strand of DNA is a polymer of nucleic acids joined covalently between the phosphate group of one and the deoxyribose sugar of the next to for a backbone from which the nitrogenous bases stick out. Also describe and explain the relationship between melting temperature Tm and GC content of DNA.

Describe the five levels of complexity of DNA structure. Be sure to include the structural elements that make up each nucleotide and the relationships between the nucleotides in a DNA molecule. They have short and easy to remember names.

ExplanationThe DNA molecule is a polymer of nucleotides. In contrast the DNA alphabet has only four letters the four nucleotide monomers. Include in your discussion the Klenow fragment of DNA.

To fit inside cells DNA is coiled tightly. DNA molecules are long so long in fact that they cant fit into cells without the right packaging. The primary structure of DNA is simply the sequence of nucleotides.

Describe in detail the structure of DNA. The second complexity of DNA. Fahadliaquat007 fahadliaquat007 04012021 Science Secondary School answered Describe the structure of DNA 2 See answers luckykumar6246 luckykumar6246.

DNA is a macromolecule consisting of two strands that twist around a common axis in a shape called a double helix. The nucleotide is formed by a combination of base sugar phosphoric acid. 3 pts Explain in detail why DNA polymerases require a primer to extend nucleotide chains.

There are four nucleotide monomers The English language has a 26 letter alphabet. Each is formed by a pentose. Explain how the molecule stores genetic information and also how that information can be changed.

DNA Structure Backbone. Strand A strand of DNA is formed by the covalent linkage nucleotides in a linear manner. The variable portion of DNA is the sequence of nitrogenous bases.

The bases on each strand are bonded to each other with hydrogen bonds. 3 pts Describe in detail the role of prokaryotic DNA polymerase III. DNA deoxyribonucleic acid molecules are nucleic acids which are the information-carrying molecules of the cell.

Describe the 3 enzymatic activities of prokaryotic DNA polymerase I. In addition indicate how a typical molecule of DNA differs from a typical molecule of RNA. Each of these chains is known as a DNA chain or a DNA strand.

16 February 2015 Dr. DNA is the molecule that holds the instructions for growth and development in every living thing. A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits.
