Document Summary
Mitosis exact duplication genetically between parent and offspring cells and between offspring cells. Meiosis (virtually) infinite genetic variability among offspring cells. Synapsis of homologous chromosomes and crossing-over occurs between homologues. Homologous chromosomes remain paired, non-homologous chromosomes align independently from one another. Allign align: interphase , replication of a chromosome, replication occurs during interphase. Dna acts as a template (i. e. , a master stand for copying) in the formation of another strand: two chromatids are produced. Each chromatid consists of one parental strand and one newly synthesized strand: gene, comments, def. A gene is a segment of dna(that is a sequence of nucleotides) that codes for production of a protein ( a macromolecule consisting of amino acids that is functional in the body: def. Amino acids are smaller molecules that are building blocks of proteins: correspondents between gene and protein. A gene consists of a sequence of nucleotides. A protein consists of a sequence of amino acids.
