What else can I help you with?
Do the rna nucleotides pair exactly as they were DNA replication?
No, RNA nucleotides in transcription pair with complementary DNA nucleotides according to the base pairing rules (A-U, G-C), as opposed to replicating DNA in which DNA nucleotides pair with complementary DNA nucleotides (A-T, G-C).
Do guanine always pair with adenine?
They pair by hydrogen bonds holding them together. Covalent bonds hold the nucleotides together, creating a sugar-phosphate backbone.
Why is DNA called polynucleotide?
DNA is called a polynucleotide because it is composed of multiple nucleotides linked together in a chain. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base, and when these nucleotides join together through phosphodiester bonds, they form a long chain called a polynucleotide.
What are individual subunits of macromolecules called?
Monosaccharides, triglyceride, amino acids, and nucleotides
What are nuclotides on DNA molecule called?
A is for Adenosine, T is for Thymine, G is for Guanine and C is for Cytosine. For RNA, U is for Uracil
Do nucleotides only pair with certain other nucleotides based on their properties?
Yes, nucleotides pair with specific complementary nucleotides based on their chemical properties.
What are the nucleotides called that pair with thymine in DNA?
Adenine always pairs with thymine in DNA.
When two nucleotides are joined to each other, what is the resulting structure called?
When two nucleotides are joined together, the resulting structure is called a dinucleotide.
Do the rna nucleotides pair exactly as they were DNA replication?
No, RNA nucleotides in transcription pair with complementary DNA nucleotides according to the base pairing rules (A-U, G-C), as opposed to replicating DNA in which DNA nucleotides pair with complementary DNA nucleotides (A-T, G-C).
Do guanine always pair with adenine?
They pair by hydrogen bonds holding them together. Covalent bonds hold the nucleotides together, creating a sugar-phosphate backbone.
DNA is made of repeating units or monomers called?
nucleotides. A nucleotide consists of a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine). These nucleotides link together in a specific sequence to form the double helix structure of DNA.
How many nucleotides that can pair up with adenine?
2

How are nucleotides in a single strand of a DNA molecule linked together?
Nucleotides in a single strand of a DNA molecule are linked together by strong chemical bonds called phosphodiester bonds. These bonds connect the sugar and phosphate groups of adjacent nucleotides, forming a long chain that makes up the DNA molecule.
Individual chains of the DNA double helix are made up of molecules called?
nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). These nucleotides are linked together by covalent bonds to form the backbone of the DNA chain.
Why are guanine and cytosine and they and adenine useful in the DNA molecules?
Guanine is a purine and Cytosine is a pyrimidine. They are nucleotides that pair together. The two are useful in DNA molecules because they pair together, along with Adenine and Thymine, which build a double helix. Guanine, Adenine, Thymine, and Cytosine are all nitrogenous bases.
