Protein Synthesis 1
What is one difference between DNA RNA?
DNA is a double strand, RNA is a single strand.
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. A protein is a chain of amino acids that are connected to each other.
There are 3 STOP codons, what are they?
UGA, UAA, and UAG
What are the two steps of protein synthesis called?
Transcription and Translation
Transcription creates what?
mRNA
Transfer RNA
What type of bond is formed between amino acids?
Peptide bonds
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 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
Using a mRNA codon wheel what amino acid does AUG code for?
Methionine
Where must an mRNA attach before a protein can be made?
mRNA must attach itself to a ribosome
Using a codon wheel what amino acid is UUG?
Leucine
What would the amino acids be in this strand of mRNA
AUG GCC UGG ACU UCA
Met(methionine), Ala(Alanine),Trp(Tryptophan), Thr(Theroline), Ser(Serine)
What does DNA stand for?
de oxy ribo nucleic acid
deoxyribonucleic 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 3 types of RNA?
mRNA, tRNA and rRNA
