Mutations
A helpful mutation
What is a beneficial mutation?
These are the three types of RNA
What are mRNA, tRNA and rRNA?
The region/location that tells RNA where to begin Transcription.
What is the promoter?
This is the RNA that has the ability move between the nucleus and cytoplasm.
What is mRNA?
The number of bases that make up a codon.
What is three amino acids?
This is how often mutations occur.
What is one in 10,000,000 bases?
These are the 3 differences between DNA and RNA.
RNA contains ribose sugar.
RNA is single stranded.
RNA contains the base uracil.
A group of genes that are regulated together.
What is an operon?
The instructions for building mRNA.
What is DNA?
The three letter code found on tRNA.
What is an anticodon?
These mutations occur when a base is either deleted or inserted.
What are frameshift mutations?
This type of RNA carries the information from DNA to the ribosome.
What is mRNA?
This happens when an organisms genome is duplicated.
What is polyploidy?
These are the pieces of post-transcriptional editing.
What are introns and exons?
This is the start codon.
What is Methionine?
A chromosomal mutation where a broken segment is reversed and put back into the chromosome.
What is inversion?
This where protein synthesis takes place in a prokaryote.
What is the cytoplasm?
Proteins used during gene expression to turn on genes.
What are transcription factors?
Give the DNA sequence AGGTCAGCT the codons would be.
UCCAGUCGA?
These are the building blocks of polypeptides.
What are amino acids?
These occur due to chemical or physical agents in the environment.
What are mutagens?
This type of RNA is made of both RNA and protein.
What is rRNA?
These are genes that regulate organs that develop into specific parts of the body.
What are homeotic genes?
These are found at the ends of a post transcriptional mRNA strand.
What is the 5' cap and the polyA tail?
These are the amount of amino acids the body has to build a protein.
What is 20?
