Transciption
The process by which genetic information is copied from DNA to RNA, is called this
What is transcription?
These are the three nucleotide units on mRNA.
What are codons?
These are the three parts of a DNA nucleotide
What is deoxyribose, phosphate group, and nitrogen base.
The Central Dogma of Biology states this:
DNA goes through transcription to make mRNA. mRNA goes through translation to make proteins.
What are the three types of RNA?
What are rRNA, tRNA (Transfer RNA), mRNA (Messenger RNA).
This is the product of transcription
What is mRNA?
This is composed of rRNA and proteins, usually both free in the cytosol and attached to the endoplasmic reticulum?
What are ribosomes?
The codons UAA, UAG, or UGA are all examples of this.
What are stop codons?
What does tRNA bring to the ribosome?
What are specific amino acids.
What is the site of transcription in eukaryotes?
What is in the nucleus.
What is the site of translation? (hint: organelle)
What are ribosomes?
These are the three parts of a RNA nucleotide
What is ribose, phosphate group, and nitrogen base.
This molecule brings amino acids into the ribosome.
What is the tRNA?
After transcription, this cap is added to mRNA
What is a GTP cap?
This is the DNA strand where mRNA is made
What is the template strand?
The tRNA has this which pairs with the codons on mRNA
What are anti-codons?
RNA differs from DNA in these 3 ways.
What is has ribose, is single stranded, and has uracil instead of thymine?
The process of adding new amino acids to each other during translation is called this.
What is Elongation?
After transcription, this is added to the end of the mRNA
What is a poly-A tail?
This is the enzyme which does transcription.
What is RNA polymerase?
The anti-codon AAA would bind to the mRNA codon sequence of UUU and would be specific for which amino acid (check chart in notes)?
What is phenylalanine?
This molecule is made in the nucleus but later can leave the nucleus.
What is RNA?
What can cause natural mutations in the DNA?
What are errors in DNA replication by DNA polymerase?
After transcription, these sections of mRNA are removed.
What are introns?
