BSC 1010 Lecture Notes - Lecture 27: Exon, Transfer Rna, Helicase
Document Summary
The genetic code has more codons than amino acids. degenerate. This enzyme adds repeated units of dna to the ends of chromosomes. When the trna"s anticodon binds to the mrna"s codon, it is called codon ____ recognition. An organism that does not have a true set of chromosomes (one or more chromosomes have greater or lesser than normal number) is said to be __. aneuploid. Meselson-stahl experiment with n14 and n15 proved that dna replicates ______ -conservatively. semi. A mutation that changes dna sequence but does not change amino acid sequence. silent. Part of trna that binds to the codon of mrna. anticodon. Codes for amino acid sequence in mrna of eukaryotes. exon. Dna has two strands (sugar phosphate backbones) that run in opposite direction is called __. anti-parallel. Enzyme that unwinds dna helix during replication. helicase. __ linked genes are found on the x chromosome in humans sex.
