QuestionAnswer
What are the 5 key features in an animal cell Nucleus, Cytoplasm, Cell membrane, Ribosomes, Mitochondria
What are the 8 key features in a plant cell Nucleus, Cytoplasm, Cell membrane, Cell wall, Ribosomes, Mitochondria, Chloroplast, Vacuole
What are the 7 key features in a yeast cell Nucleus, Cytoplasm, Cell membrane, Ribosomes, Mitochondria, Cell wall, Vacuole
What are the 6 key feartures in a bacterial cell Cytoplasm, Cell membrane, Cell wall, Ribosomes, Plasmid, Free floating DNA
What is the function of the nucleus controls all cell activity
What is the function of the cytoplasm where all chemical reactions occur
What is the function of the cell membrane controls what enters and exits the cell
What is the function of the ribosomes the site of protien synthesis
What is the function of the mitochondria the site of aerobic respiration (makes energy)
What is the function of the cell wall supports the cell
What is the function of the vacuole stores cell sap
What is the function of the chloroplast the site of photosythesis
What is the function of the plasmid extra circular piece of DNA
What is the function of the free floating DNA it contains genetic information
What is the cell wall made of in plant cells cellulose
What is Genetic Engineering when genetic information is transfered from one cell to another
What is the first stage in Genetic Engeneering identify the section of DNA that contains the required gene from source chromosome
What is the second stage in Genetic Engeneering extract required gene from chromosome using enzymes
What is the third stage in Genetic Engeneering remove plasmid from bacterial cell using the same enzymes
What is the fourth stage in Genetic Engeneeing insert required gene into bacterial plasmid using enzymes
What is the fith stage in Genetic Engeneering inset modified plasmid into host bacterial cell to produce a product
What are 2 examples of Genetic Engeneering for medicine insulin and human growth hormone
Name 3 examples of Genetically Modified foods Tomatoes with a longer shelf life Golden rice with added nutrients Potatoes with a disease resistance
What is the function of DNA DNA carries the genetic information for making protiens
What is the section of DNA that codes for a specific protien gene
how many bases are there in DNA and what are they called 4 Adenine Thymine Guanine Cytosine
What kind of stucture is DNA double helixed
How is DNA held together by the complementry base pairs
Where is DNA found in the nucleus
Where are protiens made at the ribosomes
Why can DNA not go straight to the ribosomes DNA is a double helix strucure and it to big to pass through the selectivley permeable membrane
How does the genetic information get to the ribosomes DNA makes a single stranded copy of itself that can now fit through the membrane and travel to the riobosomes
What is the single stranded molecule called mRNA (messagerRNA)
