- sex chromosome
- deoxyribonucleic acid:
- uniparental inheritance
- dioecious species
- a A cell formed by the fusion of an egg and a sperm; the unique diploid cell that will divide mitotically to create a differentiated diploid organism.
- b Inheritance pattern in which the progeny have the genotype and phenotype of one parent only, for example, inheritance of mitochrondrial genomes.
- c A chain of linked nucleotides (having deoxyribose as their sugars). Two such chains in double helical form are the fundamental substance of which genes are composed.
- d A chromosome whose presence or absence is correlated with the sex of the bearer; a chromosome that plays a role in sex determination.
- e A plant species in which male and female organs are on separate plants.
5 Multiple choice questions
- An RNA molecule transcribed from the DNA of a gene; a protein is translated from this RNA molecule by the action of ribosomes.
- An individual organism that is homozygous.
- The phenotype shown by a heterozygote.
- A section of DNA that has been inserted into a vector molecule, such as a plasmid or a phage, and then replicated to produce many copies.
- An in vitro method for amplifying a specific DNA segment that uses two primers that hybridize to opposite ends of the segment in opposite polarity and, over successive cycles, prime exponential replication of that segment only.
5 True/False questions
cytoplasmic segregation → The ribosome- and tRNA-mediated production of a polypeptide whose amino acid sequence is derived from the codon sequence of an mRNA molecule.
forward genetics → An experimental procedure that begins with a cloned segment of DNA or a protein sequence and uses it (through directed mutagenesis) to introduce programmed mutations back into the genome to investigate function.
law of equal segregation → The two strains or individual organisms that constitute the start of a genetic breeding experiment; their progeny constitute the F1 generation.
genetics → (1) The study of genes. (2) The study of inheritance.
trait → More or less synonymous with phenotype.
