Nucleic Acids | Biology | Quiz | Visionlearning
Nucleic acids are essential to life, and this quiz/worksheet will help you check What DNA and RNA are made of; The relationship between DNA and proteins. Q. Which of these nitrogenous bases is NOT in DNA? answer choices. Uracil Q . What is the relationship between a protein, a cell, and DNA? answer choices. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. Nucleic acids are condensation polymers of nucleotides. This allows RNA to carry out its important function in protein synthesis. Test your knowledge. Take quiz on Nucleic acids and inheritance.
Nucleic Acids And Protein Synthesis - ProProfs Quiz

Chemistry for Biologists: Nucleic acids
Which of the following is not a component of a nucleotide? Glycerol and fatty acids c. Five carbon pentose sugar d. Are hydrophobic and do not mix with water b.
Make up the cell walls of plants c.What is more important in your relationship quiz - Pick one test - Love personality test
Function as the enzymes. Store and transmit genetic information. The picture shows both types of fatty acids.
Fatty acid chains that are unsaturated have: An amino group b. A double bond c.
An excess of protons d. A carboxyl group Make the best match of the example to the type of macromolecule. A carbohydrate B lipid C nucleic acid D protein Proteins are made up of chains of a.
Therefore, the complementary sequence will be to the sense strand. These four strands associate into this structure because it maximizes the number of correct base pairswith A 's matched to T 's and C 's matched to G 's.
Image from Mao, Solid-state structure of complexes with alkali metal ions have been reviewed. Nucleic acid secondary structure Secondary structure is the set of interactions between bases, i.
The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. The purines are adenine and guanine. Purines consist of a double ring structure, a six membered and a five membered ring containing nitrogen.

The pyrimidines are cytosine and thymine. It has a single ringed structure, a six membered ring containing nitrogen. A purine base always pairs with a pyrimidine base guanine G pairs with cytosine C and adenine A pairs with thymine T or uracil U.
DNA's secondary structure is predominantly determined by base-pairing of the two polynucleotide strands wrapped around each other to form a double helix. Although the two strands are aligned by hydrogen bonds in base pairs, the stronger forces holding the two strands together are stacking interactions between the bases. These stacking interactions are stabilized by Van der Waals forces and hydrophobic interactions, and show a large amount of local structural variability.
The secondary structure of RNA consists of a single polynucleotide. Both single- and double-stranded regions are often found in RNA molecules.
