Biochemistry WGU C785 - Module 1 Questions and Answers latest update test Hydrophilic Correct Answer-Having an affinity for water. Hydrophobic Correct Answer-substances that are not soluble in water... . Hydrophobic substances include large, uncharged particles like fats and oils Solvent Correct Answer-A liquid substance capable of dissolving other substances Solute Correct Answer-A substance that is dissolved in a solution. Adhesive Correct Answer-Having the ability to stick to other surfaces. Cohesive Correct Answer-having the ability to stick together Heat of Vaporization Correct Answer-The amount of energy required for the liquid at its boiling point to become a gas Anticodon Correct Answer-Three-base sequence in a transfer RNA molecule base that pairs with a complementary codon in mRNA Central Dogma of Molecular Biology Correct Answer-DNA -> RNA -> Protein This paradigm was formulated by Grancis Crick: First, a portion of the DNA, a gene, is transcribed to produce a complementary strand of RNA; then RNA is translated into protein Codon Correct Answer-A specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid DNA Correct Answer-deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. Dominant Allele Correct Answer-an allele that dominates or masks the presence of another allele and is fully expressed Dominant trait Correct Answer-the trait that is expressed from a dominant allele Recessive allele Correct Answer-the trait that is completely masked and is not expressed Recessive trait Correct Answer-a genetic factor that is blocked by the presence of a dominant factor Epigenetics Correct Answer-the study of environmental influences on gene expression that occur without a DNA change Exons Correct Answer-expressed sequence of DNA; codes for a protein Gene Expression Correct Answer-process by which a gene produces its product and the product carries out its function Histones Correct Answer-they are the chief protein components of chromatin, acting as spools around which DNA winds, and playing a role in gene regulation Inheritance Correct Answer-is the passage of hereditary traits from one generation to the next Introns Correct Answer-Non-coding segments of nucleic acid that lie between coding sequences. Intervening sequences in a newly made mRNA molecule that are removed by splicing before the mRNA is released into the cytoplasm for protein synthesis mRNA Correct Answer-messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome Peptide Bond Correct Answer-covalent bond formed between amino acids Polypeptides Correct Answer- Promoter Correct Answer-specific region of a gene where RNA polymerase can bind and begin transcription Ribosome Correct Answer-Cytoplasmic organelles at which proteins are synthesized. RNA Correct Answer-ribonucleic acid; a nucleic acid that plays an important role in the production of proteins RNA polymerase [Show More]
