| Question | Answer |
|---|---|
| where does transcription take place | nucleus |
| where does translation take place | cytoplasm |
| does transcription involve dna | yes |
| does translation involve dna | no |
| does transcription involve rna | yes |
| does translation involve rna | yes |
| what type of rna is involved with transcription | mrna |
| what type of rna is involved with translation | trna mrna rrna |
| what type of organic molecule is in transcription | nucleic acid |
| what type of organic molecule is in translation | nucleic acid |
| end product of transcription | mrna |
| end product of translation | protein |
| during dna replication the dna molecule blank into two strands | seperates |
| at the end of dna replication blank strands have been produced | two |
| making a total of blank strands of dna | four |
| new dna is replicated in strands complementary to old dna because production of new dna follows the rules of blank | base pairing |
| is the structure of eukaryotic chromosome compact in mitosis | yes |
| copying part of a nucleotide sequence of dna into a complementary sequence in rna is called blank | transcription |
| an enzyme that binds to dna during transcription is blank blank | polymerase rna |
| during the process of blank the information carried by mrna is used to produce proteins | translation |
| each trna molecule contains three bases called the blank which ensure that amino acids are added in the correct sequence | anticodon |
| what is dna and rna | long chain of nucleotides |
| mrna | carries proteins assembly instructions |
| trna | carries amino acids used by construction of proteins |
| rrna | helps assemble proteins |
| genetic information is altered when changes in the DNA sequence called | mutations |
| changes in the dna sequence of an entire chromosome is affected by | chromosomal mutations |
| process in which one strain of bacteria appears to change into another one | transformation |
| virus that infects and kills bacteria | bacteriophage |
| proteins that dna wraps around in eukaryotic chromosomes | histones |
| signal in dna that indicates to enzymes where to bind to make rna | promoter |
| the principal enzyme involved in dna replication | dna polymerase |
| three nucleotides that specify a single amino acid to be added to a polypeptide | codon |
| a change in dna sequence that affects genetic information | mutation |
| gene that is transcribed into rna | expressed gene |
| a blank is made up of three parts a deoxyribose molecule a phosphate group and a nitrogenous base | nucleotide |
| the principle of blank states hydrogen bonds can form only between certain bases in dna | base pairing |
| the decoding of an mrna message into a protein is known as | translation |
