WGU Biochem C785: Unit 4
DNA and RNA DNA (deoxyribonucleic acid) - CORRECT ANSWER An organisms genetic material found in the nucleus of a cell Double stranded helical nucleic acid molecule consisting of nucleotide monomers with deoxyribose sugar and nitrogenous bases (A, C, G, T) capable of replicating Which nucleotides/bases are used in DNA? - CORRECT ANSWER A - Adenine C - Cystine G - Guanine T - Thymine RNA (ribonucleic acid) - CORRECT ANSWER A nucleic acid consisting of nucleotide monomers with a ribose sugar and nitrogenous bases (A, C, G, U) Usually single stranded Functions in protein synthesis, gene regulation, and as the genome of some viruses 1 / 3
Central Dogma - CORRECT ANSWER DNA -> RNA -> Protein DNA -> Transcription ->mRNA -> Translation -> Protein The process by which the instructions in DNA are converted into a functional product The flow of genetic information from DNA to RNA protein Which nucleotides/bases are used in RNA? - CORRECT ANSWER A - Adenine C - Cystine G - Guanine U - Uracil Which nucleotides/bases pair together to form DNA? - CORRECT
ANSWER A - T
C - G Which nucleotides/bases pair together to form RNA? - CORRECT
ANSWER A - U
C - G 2 / 3
Genes - CORRECT ANSWER A segment of a DNA molecule that information or directions on how to build a protein Gene Expression - CORRECT ANSWER When a gene in DNA is "turned on" or used to make the protein is specifies
Includes 2 Stages: Transcription and Translation
Nucleotides - CORRECT ANSWER Basic units of DNA molecule, composed of a sugar, a phosphate, and one of 4 DNA bases Antiparallel - CORRECT ANSWER The opposite arrangement of the sugar-phosphate backbones in a DNA double helix (5'-
3', 3'-5')
Complementary (coding) Strand - CORRECT ANSWER A strand of DNA or RNA that has complementary bases to the template strand, another strand of DNA or RNA
