What is the difference from DNA nucleotide and DNA polymer?
A nucleotide is a single structural unit of DNA. If two or more nucleotides are combined together by a polymerase enzyme, the resulting molecule is a polymer. RNA is also composed of nucleotides and can be formed into polymers.
What are two larger molecules made up of nucleotides?
DNA and RNA are made up of nucleotides.
Relationship between Nucleic Acids and Nucleotides?
Nucleotides are the building blocks of DNA. Each nucleotide consists of a sugar (in the case of DNA, deoxyribose), a phosphate group, and one nitrogenous base (Adenine, Thymine, Guanine,or Cytosine). The DNA molecule is a double helix of two long strings of nucleotides.
What links the two strands in a helix together in the middle?
Bases with hydrogen bonds are the links.
What is the reaction that links two monosaccharides together?
Monosaccharides are bonded together through the process of dehydration synthesis.
What is the type of bond that links two nucleotides together in a strand of DNA?
Gangnam Style
The two polynucleotide chains in DNA molecule are attracted to each other by what?
Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.
How do the radioactively labeled dideoxynucleotides terminate DNA synthesis?
Dideoxynucleotides have no OH group on the sugar of the nucleotides, only H's. That means phosphate groups can't react with the sugar to form a phosphodiester bond to join two nucleotides together, so DNA syntheses is terminated
What nucleotides can be held together by weak hydrogen bonds?
DNA contains four nucleotide bases, which are adenine, thymine, cytosine and guanine. The pairs of nucleotides that can be held together by weak hydrogen bonds are purines and pyrimidines.
Name of substance that DNA is composed of?
DNA (deoxyribonucleic acid) is a double stranded polynucleotide. It is made of two anti-parallel strands of many individual units called nucleotides joined together. The nucleotides themselves consist of a phosphate group, a pentose sugar (in the nucleotides of DNA the pentose sugar present is deoxyribose) and a nitrogenous base (in the nucleotides of DNA the bases are adenine, thymine, guanine and cytosine).
What joins sugars to phosphate groups in nucleotides?
Covalent bonds. Hydrogen bonds join together the two nucleic bases on the nucleotides to make the double helix.
What happens in the bonding of two nucleotides?
Phophodiester bonds are the one that connect the nucleotides next to each other on the same strand. Weak hydrogen bonds join the two complementary nucleotides and thus the two strands of the DNA together.
What is the name of the nerve that links the two hemispheres together?
corpus colossum is the structure that links the two hemisphere together. It is made by commisural fibres. I'm not sure about the specific name of the nerve that links the two hemisphere together.
That which joins or links two things together?
That which joins or links two things together?
What is the function of DNA polymerase?
DNA polymerases are the enzymes responsible for joining DNA nucleotides together. In Prokaryotes - DNA Pol III is the enzyme which adds nucleotides to the new strand during DNA replication. DNA Pol I is responsible for replacing the primers with DNA nucleotides.
What Joins or links two things together?
couple
What is the structure of DNA and nucleotide?
A DNA nucleotide is composed of the 5-carbon sugar deoxyribose, a phosphate group, and one of four nitrogen bases; adenine (A), thymine (T), cytosine (C), and quanine (G). A molecule of DNA is composed of two strands of nucleotides. The nucleotide strands are oriented such that the sugar and phosphate groups alternate down the outside of the strand, and the nitrogen bases are oriented toward the center of the two strands. In a DNA molecule, the two strands of nucleotides pair according to the base-pairing rule, which states that adenine pairs with thymine (A-T), and cytosine pairs with guanine (C-G). The nitrogen bases of the complimentary strands of DNA are held together by hydrogen bonds. Because of the 3-D structure of the nucleotides, the two DNA strands twist into a double helix, often likened to a twisted ladder. Refer to related links for illustrations.
