Topic 1.1 Quiz (Science 10)Summary:Concept 1: DNA contains the code for all living things. It is the reason for diversity; even small changes in DNA can cause dramatic differences.Concept 2: Review structure of DNAConcept 3 (focus): DNA is packaged in chromosomes for cell division. Homologous chromosomes have the same length, centromere position, and genes, but may have different alleles (versions of genes). During meiosis, homologous chromosomes are split to produce gametes. During fertilization, half the chromosomes are inherited from each parent makes new combination of allelesA karyotype is a picture of all the organism’s chromosomes: it contains autosomes and sex chromosomes. Concept 4: In DNA replication, complementary base pairs are formed. Learning Map Criteria:RelevanceExtendingProficientDevelopingEmerging?Given the code of a template strand of DNA, write the mRNA code and the amino acid sequence with its associated protein. Explain how DNA is transcribed into mRNA and translated into amino acids. Given a chromosome (with genes/alleles), draw its homologous pair. Explain any similarities and differences.Given the karyotype of a haploid cell (e.g. sperm cell), draw the karyotype of a matching haploid cell (e.g. egg cell.Recognize that DNA contains the code for proteins. List three functions that proteins can have. Identify and differentiate between different chromosomes and homologous pairs of chromosomes, in a karyotype. Count the number of chromosomes and homologous pairs in a karyotype.Determine the sex of an individual organism from its karyotype.Define autosome and sex chromosome.Identify and differentiate between genes and alleles. Given the code of a template strand of DNA, write the complementary strand. Label the structures and components of DNA (double helix, nucleotide, adenine, thymine, cytosine, guanine).Recognize that in meiosis, homologous chromosomes are separated. In fertilization, chromosome number doubles as one set of chromosomes is inherited from each parent.Understand that nucleic acids (DNA and RNA) contain the information for all living things, and that it is inherited by future generations.
