Word cards/games Activities used to enable learning new words and concepts in a fun and interactive way Concept map- Ask them to form groups of three and arrange a concept map with one set of the words. This is a useful activity to conceptualise the material. If time and resources permits this activity could be done individually. By doing the activity individually on a large sheet of paper and asking the students to write on the paper how the terms are linked. An increased insight into the student’s conceptions could be gained. Word game - Give students relevant word cards (see below) Ask them to pair the word with its definition Fun Interactive Word review game Place the students in groups of 3-4 students. Each group uses one set of cards Place the cards with the writing facing down on the desk One student takes the top card and gives clues to help the other students guess the word written on the card Students should be instructed to use only biological hints or clues (e.g. no "sounds like" or references to popular culture). If the student who picks up a card does not know how to explain it, show it to the other students and get help with a definition, then place the card at the bottom of the pack again. Pick up a new card The person who guesses the target word correctly gets the card and takes the next card from the deck to give clues to the other students. If a student picks up the cards with the definition on it he reads it out and whoever calls out the right term gets the card Once the deck is completed the student with the most cards is the winner. Alternatively, two students can play together and there will not be a winner (or loser). (Activity modified from activity from Bryn Mawr College, Pennsylvania, USA website http://serendip.brynmawr.edu/exchange/bioactivities/cellvocab) Material needed: A set of 34 relevant word and definition are enclosed below. (Photocopy and laminate). Reference: Words and definitions from the vcaa study site and pictures selected from Google images. tRNA Translation Transcription Stop codon UAA UAG Semiconservative replication UGA A molecule found in the cytoplasm of a cell which brings specific amino acids to the ribosome to be formed into a polypeptide The process of protein synthesis that occurs in the cytoplasm of cells. The mRNA molecule is read by the ribosomes and amino acids are ordered to form a polypeptide The synthesis of mRNA from a template strand of DNA in the nucleus A sequence of three nucleotides that codes for the end of a gene The replication of DNA that results in each new double stranded DNA consists of one strand from the original molecule and one newly synthesized strand RNA polymerase Primers Polypeptide Plasmid Mutagen An enzyme that produces RNA A short fragment of RNA that is complementary to a region of single stranded DNA and is able to bind to it, stimulating the enzyme DNA polymerase to copy the nucleotide bases on the exposed section of DNA near the primer and create a double stranded molecule A molecule consisting of a single chain of many amino acids linked together by peptide bonds A piece of DNA found in bacteria and yeast that is able to replicate independently of the main chromosome/s of the cell An environmental influence that is able to cause change in one or more nucleotide bases of the genetic material Genotype Phenotyp e PCR Nucleotides The genetic profile of an individual- the range of alleles of each gene the organism possesses. The visible physical or nonvisible physiological outcomes of gene expression ( also dependent on environment) a procedure in which the enzyme DNA polymerase is used to clone (copy exactly) a specific sequence of DNA without the need of a living cell a sub-unit of nucleic acids that has a distinct structure consisting of a 5carbon sugar, a phosphate group and a nitrogenous base Mutation A change in the sequence of nucleotide bases of the genetic material mRNA Locus Intron The group of RNA molecules that transcribes the genetic information from the DNA in the nucleus The position of a gene on a chromosome A nucleotide sequence of a gene that doesn’t code for a gene product or control sequence and is thus taken out during transcription Insertion Gene linkage Genome Gene expression the addition of one or more nucleotides to a DNA sequence Traits that tend to be inherited together as they are located on the same chromosome The total DNA of the haploid set of chromosomes in an organism Conversion of the information held in DNA to mRNA and then to a protein or other functional gene product Gene Frameshift mutation Exon An inherited unit of DNA molecules (chromosomes) that controls a structure or function of an organism A type of mutation caused by the deletion or addition of a single nucleotide in a codon that results in a change in the reading frame of the codonsshifts the whole sequence A nucleotide sequence of a gene that codes for an amino acid sequence or a control sequence DNA template The strand of DNA that acts as a ‘template’ for mRNA in the process of transcription DNA sequencing Sequencing methods for determining the specific base sequence in DNA DNA polymerase DNA ligase The enzyme that catalyzes the assembly of deoxyribonucleoside triphosphate building blocks onto the DNA in the 3’ to 5’ direction The enzyme that synthesizes bonds between adjacent nucleotides Deletion Allele Anticodon Chromosome The process of removal of one or more bases from DNA or of a section of a DNA molecule from a chromosome A variation of a gene A sequence of three nucleotides on a molecules of tRNA that is complementary to the base sequences on a codon of mRNA A structure containing DNA and proteins which carry genetic information (linear in eukaryotes, ring shaped in prokaryotes) A group of three nucleotides (triplet) of DNA or RNA Codon Reference: Words and definitions from vcaa study site and pictures selected from Google images.
