Copy That!
What is semi-conservative?
This type of mutation does not cause a change in the amino acid formed.
What is a silent mutation?
What are adenine, thymine, guanine and cytosine?
What is an inducible operon?
mRNA cannot carry thymine. Instead is carries this nucleotide.
What is uracil?
What is helicase?
This type of mutation occurs when a STOP codon appears at the beginning of the gene.
What is a nonsense mutation?
Chargaff proposed that these bases are always complimentary.
What adenine and thymine or cytosine and guanine?
In prokaryotes, these proteins are activated to block transcription.
What are repressor proteins?
AAT-CGT-CCG of the noncoding strand of DNA becomes this in mRNA.
What is UUA-GCA-GGC
New DNA is built from this direction.
What is the 5' to 3' direction?
What is a frameshift mutation?
What is circular?
The regulation of the histones holding together the DNRA by tightening or loosening the strands is called this.
What is epigenetics?
These fragments of DNA are removed from the mRNA after transcription.
What are introns?
This new strand is built with the direction the replication is unwinding.
What is the leading strand?
What is a retrovirus?
What are bacteria (prokaryotes)?
This is an example of gene expression when a rabbit's fur color changes in response to the changing seasons.
What is phenotypic plasticity?
Alternative variations of the gene can be transcribed using this process.
What is alternative splicing?
This enzyme is needed to join the fragments of the lagging strand.
What is ligase?
Sickle cell anemia is caused by this type of mutation.
What is a point mutation?
What is a eukaryotic cell?
In eurkaryotes, when a protein is phosphorylated so it changes shape is called this type of modification.
What is a post-translational modification?
These are added to the end of the mRNA strand to prevent degradation as it moves out of the nucleus.
