Section II Flashcards
What is the second step in transcription
Free floating RNA nucleotides line with the appropriate DNA base
What is the first step in transcription
An enzyme, RNA polymerase, unzips DNA
3rd step in transcription
Continues until the RNA comes to a “stop” sequence and releases the DNA
Last step in transcription
RNA moves out of the cell nucleus
The formation of proteins using information coded on the DNA and carried out by RNA
Protein synthesis
Proteins may consist of hundreds or thousands or ___
Amino acids
Amino acids are connected by ___ bonds
Peptide
___ amino acids are found within our body
20
In the amino acid code proteins are read as ___
Codons
Process of making proteins from the mRNA
Translation
Translation is also referred to as ___
Protein synthesis
Translation occurs at the ___
Ribosome
The first 3 steps in translation
- mRNA passes out of the nucleus through the nuclear membrane and moves to a ___
- The mRNA attaches to the ribosome at the ___
- The ___ is always AUG
- Ribosome
- Start codon
- Start codon
The 4,5,6 steps in translation
- The mRNAnis read in a series of 3 nitrogen bases at a time-referred to as ___
- Ribosome signals the tRNA w/ the matching ___ to bring in the appropriate amino acids
- The tRNA at the __-site is releases, but the on at the __-site stays
- Codons
- Anticodons
- P, A
The last two steps in translation
- Ribosomes move to open up the __-site
- The amino acids bond by a ___ bond to form ___
- A
