Document Summary
Nitrogen base (a, g, t, c or u) New bases line up and bind with complementary bases. Sugar, phosphate and base (a, g, c, u) Transfer rna (trna) brings specified amino acids to ribosome trna binds to codon. Amino acids join together: polypeptide chain: the genetic code and protein. Segment of dna specifying sequence of amino acids in particular protein. More than 1 codon may code for single amino acids. 1st and 2nd letter of codon will generally change amino acid (3rd letter seldom changes) Clogging of blood cells: dna and cells. Chromosome: tightly coiled strands of dna and protein. Alike in shape, size and influence same traits. Wild type: most frequent or normal form of phenotype or allele. 1 pair (xx or xy: human karyotype. Mitosis: somatic cells: dna replication, chromosomes line up at center of cell, split from each other at centromere.
