1. is/arewouldcando/ does couldwill When When the nucleotide is part of DNA when the DNA molecule it is copying, has an adenine base only when the tRNA base sequence is complimentary to the mRNA At high temperatures or extreme pHs when an RNA molecule is synthesised if it is an RNA nucleotide What the proteomeMessenger RNA the protein will no longer carry out its function which could affect structural components of a cell or cell metabolism mRNA moves into the ribosome (rRNA) and the base sequence is ‘read’ and translated into the appropriate polypeptide chain “new” shape could prevent normal functioning of protein, eg active site no longer can catalyse reaction a gene may code for more than one protein depending on its cell environ, ie its location in the organism Why DNA bases determine the sequence of amino acids, which in turn help the protein form its four levels of structure, that determines its function It contains more that one polypeptide chain determine the shape and thus function of proteins, & carry out critical functions, eg enzymes, incorrect formation of proteins can be detrimental because of the interaction between proteins, and the reliance that some have on others the ribosomes wouldn’t be able to read the correct base sequence and translate into right polypeptide chain many diseases are due to the malfunction of proteins, not just mutations. Hence targeting genes alone is not sufficient to combat all types of diseases Where a) cytoplasm b) nucleus at the ribosomesat the receptors of the cell In the rough ER, although question a bit confusing as a structural component of ribosomes in the nucleus of the cell Which it has been man-made polypeptide ultimately both will have the same effect; a mutation or change in the tertiary structure will result in a faulty protein and hence will limit or disable its function thymineribosomeMessenger How because continual research will enable scientist to mimic a protein to perform a certain activity a change in the secondary structure would affect the H- bonding b/n amino acids and would hence affect the protein’s overall shape (or active site) DNA contain deoxyribose sugar and bases GTAC, RNA contain ribose sugar and GUAC Only “matching” tRNA (carrying amino acid) can have amino acid added to chain Inhibit the action of an enzyme or mimic the enzyme (if it was faulty) if two polypeptides combine together a protein reach its quaternary level? a designer drug affect a biochemical pathway? an RNA strand get translated in the ribosome? one tell the difference between RNA and DNA nucleotides? a mutation in the secondary structure of a protein ultimately affect the protein's function? the research of proteomics benefiting in designing certain drugs? type of RNA will be responsible for the transcription process of protein synthesis? organelle (could) synthesise proteins? nitrogenous base (does) get replaced by uracil in RNA? more greatly affect the function of a protein: a mutation in the genes or in the tertiary structure? substance (would) be created after translation of mRNA? a characteristic of a designer drug that makes it differ from something our body would produce? transcription occur? rRNA be found in a cell? amino acids characterise the packaging of proteins? a designer drug have an impact on a cell so that the invading virus cannot enter a host cell? the translation of an mRNA molecule occur? DNA located in a) Prokaryote cell b) Eukaryote cell designer drugs be designed to target mutations in the genes not help in fighting all types of diseases? a ribosomes mutation affect the making of a protein? proteomics concentrate on a range of different proteins rather than just one? a simple mutation in ones genes, be detrimental? you call haemoglobin an example of a protein with a quaternary structure? the bases of DNA so important in the synthesis of proteins? cause the same gene to code for different types of proteins? happen if a protein is synthesised with a mutation? the rRNA molecule do in the synthesis of proteins? result in the manufacturing of a faulty protein? substance (would) be produced from transcription of DNA? is the sum of all proteins produced in an organism referred to as? a uracil be present in the nitrogenous base of a nucleotide? Uracil replace Thymine? proteins get denatured? the mRNA bond to the tRNA during the translation stage of protein synthesis? uracil be added to a growing mRNA molecule? a sugar deoxyribose part of a nucleotide?

2. is/arewouldcando/ does couldwill When is a cell not undergoing mitosis? the rate of respiration exceed photosynthesis? water pass across a membrane into a cell? ATP get used for movement across cell membranes? enzymes be denatured? alcohol begin to be produced in plant cells and yeast? What glucose broken down into during glycolysis? be an element in proteins that is not in lipids? be made from a chain of nucleotides? endoplasmic reticulum do in a cell? be the stage of mitosis where chromatids are pulled apart? the main waste product of aerobic respiration? Why bacteria referred to as prokaryotes? osmosis also be referred to as a special case of diffusion? active transport move molecules from low to high concentration? cells have a certain size limit? a cell with a cell wall not necessarily be a plant cell? the reaction rate be affected by substrate concentration? Where 2 ATP produced during glycolysis? photosynthesis occur in a plant cell? you find in a cell the process of fermentation occurring? plant cells produce glucose? you place a RBC for it to lyse (burst open)? amino acids be combined to form proteins? Which is the organelle involved in aerobic respiration? be a protein, galactose or carbonic anhydrase? pass through the membrane bi-layer, sugar or H 2 O? more membrane damage, a hypotonic or isotonic sol? affect photosynthesis more, no CO 2 or no chlorophyll? lower enzyme activity, decrease in pH or temperature? How carbohydrates chemically different to lipids? ions pass across a plasma membrane? you identify a eukaryotic cell? a fungal cell differ to that of a plant cell? you identify the main role of a cell is to release hormones?
