Biol 1001 Exam 4 hrincevich Test
Questions with Complete Solutions.
DNA contains the ____ ____ of every cell - Answer molecular blueprint
proteins are the ____ ____ of the cell - Answer construction workers
proteins control - Answer cell shape
function
reproduction
synthesis of biomolecules
there is a flow of information from ____ to _____ - Answer DNA; protein
DNA in eukaryotes is kept in the - Answer nucleus
Protein synthesis occurs at ____ in ____ - Answer ribosomes; cytoplasm
DNA infor is carried by ____ from the nucleus to the cytoplasm - Answer RNA
RNA differs from DNA - Answer single-stranded
uses sugar ribose
base uracil
messenger RNA - Answer carries DNA gene information to the ribosome
single-stranded "intermediate copy" of DNA - Answer mRNA
transfer RNA - Answer carries amino acids to the ribosomes for addition to the growing
protein
have a "cloverlead" shape - Answer tRNA
ribosomal RNA - Answer part of the structure of ribosomes
, each ribosome consists of two subunits - one small and one large - Answer rRNA
genetic information is transcribed into ____ and then translated into ____ - Answer RNA;
protein
information in a DNA gene is copied into mRNA in the process of - Answer transcription
mRNA, tRNAs carrying amino acids, and a ribosome, synthesizes a protein in the process of -
Answer translation
genetic code - Answer translates the nucleotide sequence into amino acids in proteins
bases in mRNA are read by the ribosome in triplets called - Answer codons
individuals who cracked genetic code - Answer nirenberg and matthaei
nirenberg and matthaei's experiment - Answer created artificial mRNAs of known sequence
and observed what proteins they produced
mRNA start codon - Answer AUG
three stop codons - Answer UAA, UAG, UGA
transcription of a DNA gene into RNA has three stages - Answer 1. initiation
2. elongation
3. termination
transcription initiation stage 1 - Answer RNA polymerase binds to the promoter region at the
beginning of a gene
transcription initiation stage 2 - Answer the DNA molecule is unwound and strands are
separated at the beginning of the gene sequence (this creates single strand regions of the DNA)
transcription elongation - Answer - generates a growing strand of RNA
- knows what to make since it "reads" the DNA template strand
- the bases in the newly synthesized RNA strand are complementary to the DNA template strand
