Transcription (BIO) Flashcards
Carries amino acids to the mRNA through the ribosome, used in translation, makes an anticodon
tRNA
Transfer
Makes up the ribosome used in translation, has a large subunit and a small subunit
rRNA
ribosomal
Carries the genetic info from DNA that tell the ribosomes what amino acids should be added, used in transcription and translation
mRNA
messenger
mRNA is translated to what?
Protein
Are the key to cellular structure and metabolism
Protein
are proteins that help turn specific genes “on” or “off” by binding to nearby DNA.
Transcription factors
is the process where a gene’s DNA sequence is copied ( ) into an RNA molecule. ( ) is a key step in using information from a gene to make a protein.
Transcription
is when a gene in DNA is “turned on,” that is, used to make the protein it specifies. Not all the genes in your body are turned on at the same time, or in the same cells or parts of the body.
Gene Expression
What are the 3 transcription factors?
- Activators
- Repressors
- Binding Sites
a protein that binds to DNA and stimulates transcription of a gene
Activator
to inhibit expression of a particular gene.
Repressor
what is often called “junk DNA” that seem to make up the majority of the code?
bases that are transcribed but are later removed
Introns
bases that code for amino acids
Exons
biological catalysts that are RNA molecules
Ribozymes
removes introns from a transcribed pre-mRNA, a type of primary transcript.
splicesomes
