Benchmark #5 Flashcards
What type(s) of point mutations will not cause a frame shift
Substitution
What is the product of transcription
RNA molecules
Which type of RNA transports amino acids to the ribosome
TRNA
Where would an anti-codon be located
TRNA
What is/are used to cut DNA in specific locations?
Restriction enzymes
What did Watson and Crick discover?
The structure if DNA to be a double helix
What does helicase do?
Unzips the DNA molecule
Differences b/w DNA and RNA?
- ribose instead of deoxyribose
- singe not double stranded
- uses uracil in place of thymine
What does mRNA do?
Brings instructions from DNA to the cytoplasm
What does rRNA do?
Site where protein assembly happens (ribosomes are made of this)
What does tRNA do?
Brings amino acids to rRNA for assembly
What does transcription do?
Makes a mRNA copy of DNA
Transcription: what unzips the DNA molecule?
RNA polymerase (enzyme)
What are promoters?
Sequence of bases that tells RNA polymerase where to start transcription
What is the purpose of DNA replication?
Copy DNA
When in the cell cycle does this take place?
“S” phase
Made of monomers called nucleotides? DNA or RNA?
DNA
