ANP 201 Lecture Notes - Haplotype, Somatic Cell, Allosome
Document Summary
Dna is the chemical that makes up each chromosome, contained in. Within each chromosome, dna molecules (nucleotides) form a. *dna the nucleus of the cell sequence, or code. 3 big questions: what is the genetic code, what does the genetic code (dna) do, what is the genetic structure of human variation. *chemical template for every aspect of an organism. *contains coding regions (genes) and non-coding regions ( junk dna) Sugar phosphate backbone paired with a nitrogen base. The characteristics (#, size, type, etc. ) of the complete set of chromosomes contained within each somatic cell for an organism or a species. *cells in our world have two basic types. *results in four, non-identical haploid gamete cells (4 sperm cells/1 egg cell) *cross-over: the process by which homologous chromosomes wrap around each other and exchange genetic info during meiosis. *recombination: the exchange of genetic material between homologous chromosomes as a result of cross-over.
