- Ribosomal RNA
- Missense mutation
- a Type of nuclear division. A reduction division. The chromosome number is halved. It involves two divisions. It produces cells that are genetically different from each other and from the parent cell.
- b A change in DNA sequence that leads to a change in the amino acid sequence coded for by a gene.
- c A stretch of DNA consisting of two or more genes that are transcribed together and coregulated.
- d Three types of RNA that form an important structural and functional role within the ribosome.
- e Alleles present within cells of an individual, for a particular trait/characteristic.
5 Multiple choice questions
- Genes that control the development of polarity within a body segment during development.
- Eukaryotic cell or organism that has two identical alleles for a specific gene.
- Characteristic in which the allele responsible is expressed in the phenotype even in those with heterozygous genotypes.
- Eukaryotic cell or organism having only one set of chromosomes. Denoted by n.
- A change in DNA sequence within a gene that does not lead to a change in the amino acid sequence due to the degeneracy of the genetic code.
5 True/False questions
Insertion/deletion mutation → A change in DNA sequence within a gene that does not lead to a change in the amino acid sequence due to the degeneracy of the genetic code.
Discontinuous variation → Variation of genetic information in a gene pool.
Diploid → Eukaryotic cell or organism having only one set of chromosomes. Denoted by n.
Homeobox genes → Genes that control the development of the body plan of an organism.
Degenerate → A term applied to the genetic code that describes the fact that more than one triplet code is used to code for all amino acids other than tryptophan and methionine.
