(LO 2.8) Think about antiparallel alignment of nucleic acids and complementary base pairing. The 5' and 3' below indicate which end of the nucleic acids is which. Which of the following is the DNA strand complementary to the DNA strand 5'-GATCT-3'? 5'-AGAUC-3' 5-AGATC-3' 5-CTAGA-3' 5-CUAGA-3' 5'-GATCT-3'
(LO 2.8) Which of the following pairs would you find across two molecules of DNA in a double helix? thymine (T) paired to cytosine (C) adenine (A) paired to uracil (U) guanine (G) paired to adenine (A) adenine (A) paired to thymine (T)
(LO 2.8) A single molecule (strand) of DNA is half of a double helix. The backbone that makes the polymer of this single molecule of DNA is made of covalent bonds between phosphate groups and nitrogenous bases. covalent bonds between phosphate and sugar groups. peptide bonds between sugars and amino groups. peptide bonds between amino and carboxyl groups. hydrogen bonds between nitrogenous bases.
(LO 2.12) The enzyme family tRNA synthetase makes the ribosomes that tRNA binds do during translation. adds the correct amino acid to each tRNA. makes tRNA from the sequence of nucleotides in DNA at the tRNA gene. binds to the A site of ribosomes. reads the codons on the tRNA by complementary base pairing.
(LO 2.11) Which of the list below happens most immediately after free ribonucleotides first base pair with the template strand of DNA during transcription? Covalent bonds are made between sugars and phosphates of ribonucleotides. The TRNA with the start codon initiates transcription. The DNA is replicated by RNA polymerase. The RNA polymerase reaches the stop codon, which terminates transcription. Covalent peptide bonds are formed.
Some segments of a protein strand coil, somewhat like a metal spring, because a. amino acids at different places along the strand are chemically attracted to each other. b. the protein strand has been denatured by acid. c. the protein strand is missing one or more essential amino acids. d. a coil structure allows access by enzymes for digestion.
(LO 2.9) What amino acid sequence would be made by the following MRNA 5'-AUGACAUUUUCGCACUAA Thr-Phe-Ser-His Met-Ser-Ala-Lys-Pro-Phe Met-Asp-lle-Phe-Ala-Leu Met-Thr-Phe-Ser-His Asp-lle-Phe-Ala-Leu

LO 53- Determine the type of mutations based on the effect in the amino acid chain "missense, nonsense, silent and neutral"- that occurred in a sequence. A mutation in a DNA sequence leads to a shorter protein when compared to the wild-type protein. This means: The mutation is missense because the protein is shorter The mutation is neutral because it leads to a stop codon earlier than the wild-type sequence The mutation is nonsense because it leads to a stop codon earlier than the wild-type sequence. The change represents a gain of function mutation The mutation is nonsense because it leads to a stop codon at a later codon than the wild-type sequence
Draw out the following DNA sequence on a white sheet of paper along with itscomplementary strand. Challenge yourself by not using any notes to begin with. Use hexagon and hexagon/pentagon shapes within the nitrogenous bases to depict purines and pyrimidines. Use circles and pentagons to show phosphates and sugars in the backbones. Label the ends (5’ and 3’) and make sure to associate those ends with the correct functional group. Include the proper number of hydrogen bonds between base pairs. 3’ CCAGGTACT 5’
Correctly match the complementary base pairs in DNA. Adenine Guanine 1. Uracil 2. Cytosine 3. Thymine
