- primary transcript
- template strand
- frameshift mutation
- A site
- a 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.
- b An initial RNA transcript; also called pre-mRNA when transcribed from a protein-coding gene
- c 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.
- d One of a ribosome's three binding sites for tRNA during translation. Holds the tRNA carrying the next amino acid to be added to the polypeptide chain.
- e The DNA strand that provides the template for ordering the sequence of nucleotides in an RNA transcript.
5 Multiple Choice Questions
- A change in a gene at a single nucleotide pair
- A three-nucleotide sequence of DNA or mRNA that specifies a particular amino acid or termination signal; the basic unit of the genetic code.
- An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA.
- The synthesis of a polypeptide using the genetic information encoded in an mRNA molecule. There is a change of languagefrom nucleotides to amino acids
- The synthesis of RNA on a DNA template.
5 True/False Questions
promoter → A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA
exo- → A coding region of a eukaryotic gene or expressed region
trans- → opposite ex: anticodon
RNA processing → Modification of RNA before it leaves the nucleus, a process unique to eukaryotes.
poly-A tail → The modified end of the 3' end of an mRNA molecule consisting of the addition of some 50 to 250 adenine nucleotides.
