Karten in diesem Stapel (44)
- 1WHAT DOES THE CELL MEMBRANE DO ?CONTROLS WHAT GOES IN AND OUT OF THE CELL
- 2CYPTOPLASMCHEMICAL REACTIONS TAKE PLACE HERE
- 3NUCLEUSDONT CALL IT THIS BUT THE BRAIN
CONTROLS THE CELL - 4MITOCHONDRIARESPIRATION
- 5CELL WALLMADE OF CELLULOSE
KEEPS THE CELLS SHAPE ( BIT LIKE TUMMY TUCK ) - 6LARGE VACUOLECONTAINS CELL SAP AND KEEPS CELL RIGID
- 7CHLOROPLASTSABSORB LIGHT
- 8WHAT ABOUT CELLS AND SEEING …LIGHT MICROSCOPES ARE USED TO SEE CELLS IN DEPTH
- 9BACTERIAL CELL HAS WHAT ?CELL WALL
CELL MEMBRANE
CHROMOSOMAL DNA
PLASMID DNA
FLAGELLUM - 10FLAGELLUMTAIL TO ALLOW BACTERIAL CELL TO MOVE
- 11WHAT IS A GENEA SECTION OF DNA THAT CODES FOR A SPECIFIC PROTEIN
- 12DNA ARE TWO STRANDS OF MOLECULE CALLEDDOUBLE HELIX
- 13WHAT ARE THE STRANDS LINKED BYCOMPLIMENTARY BASE PAIRS
- 14COMPLIMENTARY BASE PAIRS ARE JOINED BY WHATWEAK HYDROGEN BONDS
- 15LIST THE COMPLIMENTARY BASE PAIRSADENINE & THYMINE
CYTOSINE & GUAMINE - 16WHO DISCOVERED DNA FIRST ?WILKINS AND FRAKLIN
- 17HOW DID WILKINS AND FRANKLIN DICOVER DNAUSED XRAYS AND SHONE THEM AT PURIFIED DNA
- 18HOW DID THEY RECORD THERE RESULTSPHOTOGRAPHED THE DNA
- 19WHO DEVELOPED THE DNA DISCOVERYWATSON AND CRICK
- 20WHAT DID THEY USETHE PHOTOS WITHOUT PERMISSION AND GOT THE
- 21WHAT DID THE TWO PAIRS DISCOVERTHEY DEVELOPED THE DOUBLE HELIX MODEL
- 22WHAT IS THE HGPHUMAN GENOME PROJECT
- 23WHAT DID IT WORK OUTTHE ORDER OF THE BASES IN HUMAN CELLS A's T's G's C's
- 24WHO WORKED ON IT AND HOW LONG DID IT TAKE1000'S OF SCIENTISTS WORKED ON IT FOR 13 YEARS IN 18 COUNTRIES
- 25WHAT DOES THIS MEAN / WHAT HAS IT HELPEDTEST FOR GENETIC DISORDERS
STUDY EVOLUTION
PERSONALISE MEDICINES
DEVELOP NEW TREATMENTS - 26WHAT DOES GENETIC ENGINEERING DO ?CREATE GENETICALLY MODIFIED ORGANISMS
- 27WHAT DOES GENETIC ENGINEERING CREATE ---- GMGENETICALLY MODIFIED CELLS
- 28A GENE IS __________________________________CUT OF THE DNA
- 29HOW IS IT CUT ?USING CUTTING ENZYMES
- 30WHAT HAPPENS NEXTTHE CUTTING ENZYMES THEN CUT OPEN A DNA PLASMID
- 31THE GENE IS NOW PUT INTO THE PLASMID USING __________STICKY ENZMES
- 32THE PLASMID IS NOW PUT INTO AN _______OORGANISM
- 33WHAT HAS HAPPENEDTHE GENE HAS BEEN GENETICALLY MODIFIED
- 34WHAT IS A CLONE ?AN ORGANISM THAT IS GENETICALLY TO THE PARENT CELL ORGANISM
- 35LIST THE ADVANTAGES OF CLONING+ GENETICALLY IDENTICAL CHARACTERISTICS
+ CLONE ANIMALS THAT HAVE BEEN GENETICALLY ENGINEERED - 36LIST THE DISSADVANTAGES OF CLONING- THE PROCESS IS VERY DIFFICULT AS YOU CANNOT JUST CLONE A ARM OR LEG
-EXPENSIVE
-VERY FEW EMBROYS DEVELOP SUCSESSFULY continue - 37MORE DISSADVANTAGES=MANY ATTEMPTS FOR IT TO WORK
- POSIBBLE HELATH RICKS CAN OCCUR TO CLONED ANIMAL - 38STATE HOW TO CLONE !!!!!=THE DIPLOID NUCLUS IS TRANSFERED INTO THE ENUCLEATED EGG
= THE CELL IS THEN STIMULATED BY AND ELECTRIC PULSE TO START MIOTIC DIVISION .... CONTUINE - 39CLONING CONTIFUED-THE EMBRYO THEN BEGINS TO GROW
-THE EMBRYO IS IMPLANED INTO THE UTERUS OF THE SURROGATE MOTHER
HERE IT DEVELOPS !!! - 40WHAT CAN A STEM CELL DO WHEN IT DIVIDES- PRODUCE MORE STEM CELLS
- PRODUCE DIFFERECNIATED STEM CELL - 41WHAT IS WRONG WRONG WITH PRODUCING DIFFERENCIATEC STEM CELLSONCE DIFFERENCIATED CANNOT TURN INTO DIFFERENT TYPE OF CELL
- 42EMBRYONICE STEM CELLS CAN /......DEVELOP INTO EVERY TYPE OF HUMAN CELL
- 43LIST THE ADVANTAGES OF STEM CELLS+ INJECTEING STEM CELLS CAN TREAT DISEASES ie - LUKEMIA
+ EMBRYONIC STEM CELLS CANNOT BE REJECTED
+ CELLS CAN BECOME ANY OTHER TYPE OF CELL MEANING BEING ABLE TO TREAT MORE DISEASES - 44LIST THE DISSADVANTAGES OF USING STEM CELLS- ADULT STEM CELLS CAN BE REJECTED
= COULD BE USED ILLEGALY TO MAKE HUMAN CLONES
-CLONED CELLS COULD TURN INTO CANCER CELLS
