]> Which of the following is a correct difference between prokaryotic and eukaryotic cells? prokaryotes have a cell wall, eukaryotes do not prokaryotes are larger than eukaryotes prokaryotes have larger ribosomes than eukaryotes prokaryotes have no membrane-bound organelles Which of these terms includes all others in the list? nucleic acid nucleotide phosphate deoxyribose In double-stranded DNA, which of the following base ratios always equals 1? (A+T)/(G+C) C/T (A+G)/(C+T) G/A If one DNA strand has the sequence 5' ATTCGGCTTC 3', the complementary DNA strand would have the sequence: 5' ATTCGGCTTC 3' 5' TAAGCCGAAG 3' 5' CTTCGGCTTA 3' 5' GAAGCCGAAT 3' The transcription of DNA to a molecule of messenger RNA occurs: on the ribosomes in the cytosol in the nucleus when amino acids are made available by transfer RNA If a circular piece of DNA has three sites for a particular restriction enzyme, into how many fragments will that restriction enzyme cut the DNA? 2 4 3 The answer cannot be predicted If a linear piece of DNA has three sites for a particular restriction enzyme, into how many fragments will that restriction enzyme cut the DNA? 2 4 3 The answer cannot be predicted. The gels used in the practicals/ or described in the tutorials were made of: acrylamide agar amber agarose Electrophoresis is used to: amplify small DNA samples to obtain enough for analysis cut DNA into fragments separate fragments of DNA clone genes DNA profiles used as evidence in a criminal investigation look something like horizontal supermarket bar codes (rather than vertical). The pattern of bars/bands in a DNA profile shows the order of bases of a particular DNA molecule the order of genes along particular chromosomes the presence of various-sized fragments of DNA all of the above
