Protein Synthesis 1
What is one difference between DNA and RNA
DNA is double stranded, RNA is single stranded
What mRNA bases would pair with this DNA strand (G-G-A-T-C-G-C-C-T-T-A-G-A-A-T-C)?
C-C-U-A-G-C-G-G-A-A-U-C-U-U-A-G
Where does translation occur?
The cytoplasm (on a ribosome)
What is the difference between an amino acid and a protein?
Amino acids are the building blocks of a protein (monomer). A protein is a chain of amino acids that are connected to each other (polymer).
What would be the complementary DNA strand to (A-T-G-G-C-C-T-G-G-A-C-T-T-C-A)?
T-A-C-C-G-G-A-C-C-T-G-A-A-G-T
What are the two steps of protein synthesis called?
Transcription and Translation
Transcription creates what?
mRNA
What does tRNA stand for?
Transfer RNA
What type of bond is formed between amino acids?
Peptide bonds
There are 3 stop codons, what are they?
UGA, UAA, and UAG
What sugars do DNA and RNA have?
DNA has deoxyribose sugar and RNA has ribose sugar
Any change in a DNA sequence is called
A mutation
What is located at each end of the tRNA molecule
Anticodon and amino acid
How many amino acids are there?
20
What mRNA would be created from this strand (A-T-G-G-C-C-T-G-G-A-C-T-T-C-A)
UAC CGG ACC UGA AGU
How does mRNA leave the nucleus?
through a nuclear pore
Methionine
Where must an mRNA attach before a protein can be made?
Using a codon wheel what amino acid is UUG
Leucine
What would the amino acids be for this strand of mRNA
AUG GCC UGG ACU UCA
Methionine, Alanine, Tryptophan, Theroline, Serine
What does DNA stand for?
Deocyribonucleic Acid
Where does transcription take place?
In the nucleus
A codon is a sequence of how many bases?
3 bases
What tRNA anticodons would pair with this mRNA sequence: U-A-G-C-U-A-U-C-A-A-A-U
A-U-C-G-A-U-A-G-U-U-U-A
What are the 3 types of RNA?
mRNA, tRNA, and rRNA
