- a A type of RNA, synthesized from DNA, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein.
- b A change in a gene at a single nucleotide pair
- c The removal of noncoding portions (introns) of the RNA molecule after initial synthesis.
- d opposite ex: anticodon
- e out, outside, without
5 Multiple Choice Questions
- 1) A deficiency in a chromosome resulting from the loss of a fragment through breakage. (2) A mutational loss of one or more nucleotide pairs from a gene.
- An enzyme that links together the growing chain of ribonucleotides during transcription.
- The synthesis of a polypeptide using the genetic information encoded in an mRNA molecule. There is a change of languagefrom nucleotides to amino acids
- A specialized base triplet at one end of a tRNA molecule that recognizes a particular complementary codon on an mRNA molecule.
- A rare change in the DNA of a gene, ultimately creating genetic diversity.
5 True/False Questions
RNA processing → The removal of noncoding portions (introns) of the RNA molecule after initial synthesis.
base-pair substitution → A mutation occurring when the number of nucleotides inserted or deleted is not a multiple of three, resulting in the improper grouping of the following nucleotides into codons.
poly- → many
trans- → opposite ex: anticodon
template strand → The DNA strand that provides the template for ordering the sequence of nucleotides in an RNA transcript.
