What are the complementary base pairs that form in DNA.

What determines the primary structure of a dna molecule. What determines the primary structure of an RNA molecule. The early x-ray diffraction results indicated that DNA was composed of two strands of the polymer wound into a helix. Three dimensional shape _____ is the conversion of information in a gene to a functional gene product.

The main function of a DNA molecule is to _____. As the protein is folded into the secondary. A nucleotide is made of a phosphate a sugar a nitrogenous base.

The primary structure of DNA is simply the sequence of nucleotides. Each nucleotide is composed of a nitrogenous base a five-carbon sugar deoxyribose and a phosphate group. The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain.

A the sugar-phosphate backbone b complementary base pairing and the formation of hairpins c the sequence of deoxyribonucleotides d the sequence of ribonucleotides. The two strands of DNA run in opposite directions. The variable portion of DNA is the sequence of nitrogenous bases.

C DNA is more stable because it forms phosphodiester bonds while RNA does not. A DNA is more stable since RNA has no secondary structure. Adenine A thymine T guanine G and cytosine C.

DNA Structure Backbone 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. The sugar-phosphate chain is called the DNA backbone and it is constant throughout the entire DNA molecule. The DNA molecule is a polymer of nucleotides.

The DNA sequence will determine the amino acid sequence known as the proteins primary structure. Click to see full answer. The primary structure of a protein is determined by the gene corresponding to the protein.

The sequence of bases in the nucleic acid chain gives the primary structure of DNA or RNA. The sequence of amino acids in a protein is determined by the sequence of. Nucleic acids have a primary secondary and tertiary structure analogous to the classification of protein structure.

The sequence of ribonucleotides determines the primary structure of an RNA molecule. Early in the 1950s DNA was first examined by x-ray diffraction analysis a technique for determining the three-dimensional atomic structure of a moleculediscussed in Chapter 8. The order or sequence of these bases determines what biological instructions are contained in a strand of DNA.

The four types of nitrogen bases found in nucleotides are. The sequence of ribonucleotides DNA attains a secondary structure when hydrogen bonds for between the nitrogenous bases called purines and pyrimidines. The A and G are purines and the C and T are pyrimidines.

D DNA strands have directionality to. B DNA is a more stable molecule because it lacks a hydroxyl group on the 2 carbon. The sequences of bases in a DNA molecule will determine the amino acid sequence in the protein that it encodes for.

In DNA the nucleotide is a deoxyribonucleotide in RNA the nucleotide is a ribonucleotide. Three dimensional shape e. What determines the primary structure of a DNA molecule.

A specific sequence of nucleotides in DNA is transcribed into mRNA which is read by the ribosome in a process called translation. Control gene expression. The bases are arranged in triplets where one triplet will encode for one amino acid in a non-overlapping fashion.

The model of the double-helix structure of DNA was proposed by Watson and Crick. I Primary structure of the molecule. The shape of a protein is determined by its primary structure sequence of amino acids.

To form a strand of DNA nucleotides are linked into chains with the phosphate and sugar groups alternating. Describe how the sequence of bases in a DNA molecule would be used to form the primary structure of a protein. What determines overall protein functionality.
