Intro Flashcards
What is the role of DNA in the cell?
Holds all of the genetic information in the cell.
What is the role of mRNA in the cell?
Has a copy of some of the information - transient, short term.
What is the role of proteins and some other RNA in the cell?
Proteins and rRNA, tRNA are the “doing molecules”
What is the genome?
DNA in the cell.
What is the transcriptome?
RNA transcribed off of DNA
What is the proteome?
Proteins translated from RNA - perform active tasks in the body.
What are the different things the transcriptome can become?
Small nuclear RNA, transfer RNA, messenger RNA, ribosomal RNA, micro RNA.
What are the different things the proteome can become?
Ion channels, receptors, antibodies, enzymes, transcription factors
At what point does the process of DNA to Proteins cross over from the nucleus to the cytoplasm?
During translation when proteins are being made.
What is the central dogma of molecular biology?
DNA is transcribed into RNA and RNA is translated into proteins.
Can DNA directly make proteins?
No
Can proteins become RNA?
No
Can DNA become DNA?
Yes, this is called replication.
Can RNA become DNA?
Yes, this is called reverse transcription.
What controls gene expression?
Transcription. Really, DNA in almost every cell in your body contains the same information
