- 1Some cells have several nuclei per cell. How could such multinucleated cells be explainedThe cell underwent repeated mitosis, but cytokinesis did not occur
- 2All the following about RNA polymerase are correct exceptthe start point for transcription is AUG
- 3The following are enzymes involved with DNA replication exceptcarboxylase
- 4Work out the amino acid sequence produced from this region of DNA given that the top strand is the coding (non-transcribed) strandLys-Ala-Leu-Arg-Gln
- 5Independent assortment occurs duringMetaphase I
- 6Meiosisresults in the production of haploid gametes
- 7A cross is set up between individuals with the following genotypes. AAbb and aaBB. If the two loci assort independently, which of the following statements is trueF2 progeny will display a 9:3:3:1 phenotypic ratio
- 8This image below displays a normal DNA template, the mRNA transcript and the amino acid that codon encodes (left). to the right are four hypothetical point mutations and the resulting amino acids from the altered codons. Mutation number 1 is known as:Silent
- 9A mating of two heterozygous F1 dogs with black coats and normal vision was set up sa follows: BbNn x Bb Nn to produce the F2 generation Given that the two genes show independent assortment, what are the genotypes of the F1 gametes?BN, Bn, bN, bn
- 10Analysis of the cross AaBb x AaBb, where the genes A, with alleles A, a, and B, with alleles B, b are independently assorting, would be expected to show?the AaBb individual produces four types of gametes in equal proportions
- 11The central dogma of molecular biology suggests thatthere is a sequence of information flow from DNA to RNA to protein
- 12Which of the following statements about DNA replication is correctthe lagging strand is synthesised discontinuously in the 5' to 3' direction
- 13A kidney cell and a liver cellexpress a different subset of genes from the same chromosomes
- 14All the following statements about the cell cycle are correct exceptthe G2 stage of interphase is when chromosomes begin to condense
- 15An RNA transcript may include all these excepta promoter
- 16Mature messenger RNA from eukaryotes contains which of the following elementsexons
- 17A particular form/variant/state of a traitPhenotype
- 18If one strand of a DNA molecule has the sequence of bases 5'ATTGCA3' the other complementary strand would have the sequence5'TGCAAT3'
- 19Given the cross Dd x Ddthere would be a 3:1 ratio of dominant to recessive progeny
- 20The pedigree below shows the inheritance pattern of a human disease. there is a single gene with two alleles (A is dominant to a) found to be responsible.The mother is heterozygous
