IB Biology - Unit 7 - Nucleic Acids HL 100% Solved Antiparallel strands DNA is anti-parellel, meaning the strands run in opposite directions to each other. If one has a 3' at the top the other has a 3' at the bottom, Purines Adenine and Guanine. Pyrimidines Cytosine, Thymine and Uracil Nucleosomes Used for packing DNA, made up of a length of DNA around a group of 8 histones Supercoiling of DNA Winding of DNA strands, this can reduce the size of DNA by 10000x, using nucleos...

Biology 198 Module 4 Exam with Complete Solutions What is the Central Dogma of molecular biology? The central dogma of molecular biology explains that DNA encodes RNA through a process called transcription and RNA encodes protein through a process called translation. Describe how the information in DNA is used to produce specific proteins and can ultimately determine the characteristics of an individual organism. because of your DNA the certain RNA strand is coded from genes resulti...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANSWER Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the develop...
