Which is NOT a true statement: whereas mitosis results in diploid daughter cells

Question

Which is NOT a true statement: whereas mitosis results in diploid daughter cells; meiosis results in haploid gametes. Whereas mitosis results in identical daughter cells, meiosis results in cells that are genetically unique. Unlike mitosis, in meiosis I, homologous chromosomes (tetrads) line-up during metaphase. Crossing-over takes place in Prophase I of meiosis and Prophase II of mitosis. None of the above (All of the statements are true) PART II (Ch. 11, DNA Biology & Recombinant DNA technology) True/False In eukaryotes, transcription occurs in the nucleoid. (T/F) Chargaff's rules state that the amount of DNA base pairs (G:c and A:T) varies from species to species. (T/F) The only difference between DNA and RNA is that DNA contains deoxyribose instead of ribose. (T/F) Gene expression can be regulated by post-transcriptional RNA editing/processing. (T/F) Gene expression can be regulated at the level of protein synthesis. (T/F) Three types of RNA (mRNA, rRNA, and tRNA) are required for translation. (T/F) Complimentary base-pairing is important for DNA replication, transcription and translation. (T/F) A point mutation is more likely to be damaging than a frameshift mutation. T/F The primary structure of a protein is encoded by the base sequence of DNA. T/F The DNA sequence 3'-TAC GAT-5' would be transcribed to RNA sequence: 5' ATG CTA-3' T/F The DNA code is considered unambiguous because a given codon only specifies one amino acid T/F

Explanation / Answer

19. Which of the statement is not true?

Unlike mitosis, in meiosis 1 homologous chromosome line up during metaphase.

During prophase 1 phase the homologous chromosomes line up side by side, physically touching one another at which point crossing over is initiated. So in the metaphase the homologous chromosome do not line.

All the rest of the statements are true.
