Molecular Biology of the Gene (7th ed)/Watson goudzwaard.info . an updated section on many genomics techniques routinely employed by molecular biologists. Thus , in the beginning of the genetic analysis of Drosophila, it was often impossible to .
If the loci we're analysing are very close less than 7 cM a double crossover is very unlikely. When distances become higher, the likelihood of a double crossover increases. As the likelihood of a double crossover increases we systematically underestimate the genetic distance between two loci.
During meiosis, chromosomes assort randomly into gametes , such that the segregation of alleles of one gene is independent of alleles of another gene. This is stated in Mendel's Second Law and is known as the law of independent assortment. The law of independent assortment always holds true for genes that are located on different chromosomes, but for genes that are on the same chromosome, it does not always hold true.
As an example of independent assortment, consider the crossing of the pure-bred homozygote parental strain with genotype AABB with a different pure-bred strain with genotype aabb. A and a and B and b represent the alleles of genes A and B. Crossing these homozygous parental strains will result in F1 generation offspring that are double heterozygotes with genotype AaBb. These gametes represent recombinant gametes.
Recombinant gametes are those gametes that differ from both of the haploid gametes that made up the original diploid cell. This is a consequence of independent assortment. When two genes are close together on the same chromosome, they do not assort independently and are said to be linked.
Better contrasts the complexities of transcription initiation in eukaryotes with events in prokaryotes. RNA polymerase is now presented as a biological machine in order to better integrate transcription and processing events in eukaryotes.
A brief discussion of self-splicing introns introduces the concept of the RNA world — a thread picked up in chapter 9. Proteins and their Translation For unity, the coverage of proteins has been combined into a single chapter, including a brief introduction to proteins and Yanofsky's proof of gene and protein colinearity from former chapter on "genetics of gene function," now eliminated.
Thoroughly rewritten and updated description of translation to convey the excitement surrounding the first molecular level glimpses of the ribosome and its interactions with mRNA and tRNAs during protein synthesis.
Regulation of Gene Transcription An all-new and expanded treatment of transcription regulation in eukaryotes emphasizes the role of chromatin and epigenetic mechanisms. Topics covered include: puzzling epigenetic mechanisms such as imprinting, position effect variegation and X-chromosome inactivation the role of yeast genetics in identifying the components of the epigenetic machinery. Gene Isolation and Manipulation Combines coverage of recombinant DNA technology in a single chapter through streamlining and elimination of excessive detail.
Includes new material on genetic engineering using specific model organisms. Genomics Entirely reconceived, and extensively rewritten and updated, to provide a clear, accessible view of the strategies used to sequence genomes and to locate genes within genome sequences.
Includes new section on bioinformatics describes how scientists are analyzing the information content of the genome. Includes new section discussing what genome sequencing has told us about the structure of the human genome.
The Dynamic Genome: Transposable Elements For unity, almost everything related to transposable elements has been combined into one chapter. The story moves into the genomics age with the remarkable discovery from the human genome project that more than half of our genome is derived from transposable elements.
New sections describe how transposable elements have evolved diverse strategies to thrive in the genomes of a variety of organisms without harming their host. Simplified and Streamlined descriptions of repair systems A new section on the repair of mutagenic double strand breaks provides a logical entry point for the discussion of recombination.
Large-Scale Chromosomal Changes Two chapters in the seventh edition have been merged to make the topic less onerous and more streamlined. Dissection of gene function A new chapter in IGA, Chapter 16 describes the strategies used for forward and reverse genetics, including cutting-edge techniques such as RNAi and other types of phenocopying.
Includes examples of screens used with several model organisms.
Genetic Regulation of Cell Number: Normal and Cancer Cells Revised to achieve a smoother, more easily followed flow from concept to concept. Includes a new section on applying genomic approaches to cancer research, diagnosis, and therapies. The Genetic Basis of Development Includes new sections on sex determination in humans and genomic approaches to understanding pattern formation.
Population Genetics Quantitative Genetics Evolutionary Genetics Includes new sections on genetic evidence of common ancestry in evolution and on comparative genomics and proteomics Genetic variation in the color of corn kernels.
Each kernel represents a separate individual with a distinct genetic makeup.
Humans were breeding corn thousands of years before the advent of the modern discipline of genetics.
