There are three types of RNA listed below. Name each one and tell its function in
transcription/translation (protein synthesis)
21. mRNA messenger- single stranded molecules that carries the
instructions from a gene to make a protein (carries a message)
22. rRNA- ribosomal- part of the structure of ribosome, ribosomes are
made of rRNA and many proteins
23. tRNA- transfer- transfers amino acids to the ribosome to make
protein

Here is a list of point mutations/framshift. Describe each:
34. Insertion- addition of a nucleotide
and framshift occurs
35. Deletion-loss of a piece of a
nucleotide, cause a frameshift
36. Substitution-one nucleotide
replaces another
Here is a list of chromosomal mutations. Describe each:
37. Deletion- loss of a piece of a chromosome due to
breakage
38. Duplication- addition of a sequence
39. Inversion- segments breaks off, flips around
and reattaches
40. Translocatioin breaks off and reattaches to
non homologous chromosome
41. Nondisjunction- chromosome fails to
separate from its homologous during
meiosis, get and extra copy (trisomy 21)
