Mutations
100
RNA has this many strands.
What is 1 strand?
100
This is the name of the enzyme that creates RNA.
What is RNA polymerase?
100
Where does the translation process occur?
What is the ribosome organelle?
100
Describe what a codon is
What is a group of 3 nucleotide bases in mRNA that specifies a particular amino acid
100
Define mutation
What are heritable changes in genetic information?
200
These are the nitrogenous bases of RNA
What are Adenine, Uracil, Guanine, Cytosine.
200
This is the location where transcription takes place in eukaryotic cells?
What is the nucleus?
200
Translation starts at what specific codon
What is the start codon(AUG)?
200
This is a region in DNA where the RNA polymerase attaches to create mRNA.
What is a promoter?
200
Name the two basic types of mutations
What are gene mutations and chromosomal mutations?
300
This is the sugar that RNA cointains.
What is ribose sugar?
300
These regions of DNA show RNA polymerase exactly where to begin making RNA.
What is a promoter?
300
This carries the anticodons to pair up with the corresponding condon on the mRNA
What is the transfer RNA or tRNA?
300
In E.coli when this is not present, the repressor protein binds to the operating region, blocking the RNA polymerase from creating mRNA.
What is lactose?
300
This is a point mutation where a base is inserted into the DNA sequence
What is insertion or frameshift mutation
400
These are the three main types of RNA.
What are the messenger RNA, transfer RNA, ribosomal RNA?
400
These are the portions of RNA that are cut out and discarded.
What are introns?
400
Translation stops at one of three of these
What is a stop codon?
400
These are DNA-binding proteins that are one of the most critical in transcription of eukaryotic cells.
What are the transcription factors?
400
This mutation occurs when one part of the chromosome breaks off and attaches to another
What is translocation
500
If DNA is the master plan what is the RNA?
What is a blueprint?
500
These are the remaining pieces after RNA editing, they are spliced together to form the final mRNA.
What are exons?
500
After translation is finished, this is the result
What is a polypeptide(chains of animo acids)
500
These are very small strands of RNA that are double stranded and are not the same as mRNA, tRNA, rRNA.
What is microRNA?
500
What are the effects of mutations?
What is vary widely from catastrophic to beneficial
