Table of Contents

Genome Sequences

Abundance and complexity of mRNA

Example of mRNA from chick oviduct,

Normalized cDNA libraries

ESTs from normalized cDNA libraries

cDNA clones and ESTs

Genome sequences available

Genome sequencing after mapping

Shotgun sequencing of whole genomes

Shotgun sequencing and assembly

Directed sequencing of BAC contigs

Identifying genes in genomic DNA sequences

Computational tools for predicting genes and important sequences

Genome size

Gene size and number

Compared to worm and fly, human has shorter exons and longer introns on the extremes of the distribution

As G+C increases, gene density increases and introns get shorter

Genome size increases exponentially, but not number of genes

Databases for genomic analysis

Genetic map around MYOD1, 11p15.4

Human Genome Browser view

Ensembl view

Programs for sequence analysis

Results of BLAST search, INS vs. nr

Large scale genome organization

E. coli genome with sequence features

New insights for E. coli

Human chromosomes sequenced

Segmental duplications are common

Comparative Genomics

Paralogous genes

Core proteomes vary little in size

Little change in core proteome size in eukaryotes

Core proteomes are conserved

Types of information one can get

Functional categories in eukaryotic proteomes

Distribution of the homologues of the predicted human proteins

Conserved segments in the human and mouse genome

Expression profiling using microarrays

PSU’s microarray spotting robot

Find clusters of co-regulated genes

OTC problems 1.46-1.49 illustrate use the Web resources from genome sequencing
