Protein Synthesis 1
What is DNA?
A make up of genes for all living things.
Where does transcription take place?
In the nucleus
A codon is a sequence of how many bases?
3 bases
What tRNA codons would be needed to translate the sequence from mRNA in (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
What is the structure difference in DNA and mRNA?
DNA is a double Helix, RNA is a single Helix.
What mRNA bases would pair with DNA in this 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
Translation takes place between what two molecules?
mRNA and tRNA
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 1 Start and 3 Stops in a codon, What are they?
Start is AUG and the stops are UGA, UAA, and UAG
What are 2 parts of protein synthesis called?
Transcription and Translation
Transcription takes place between what two molecules?
DNA and mRNA
Transfer RNA
Whatever group picked this gets...
300 points!
If A matches with T, C matches with G what would this strand of genes make (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 mRNA have?
DNA has deoxyribose sugar and mRNA has ribose sugar.
Any change in a DNA sequence.
A mutation
What is located at each end of the tRNA molecule?
Codon and amino acid
How many amino acids are there?
20
If a codon of mRNA codes for U instead of T, what would change in this strand (A-T-G-G-C-C-T-G-G-A-C-T-T-C-A)?
(A-U-G-G-C-C-U-G-G-A-C-U-U-C-A)
Where is DNA and mRNA located at?
DNA is found in the nucleus, mRNA is found in the nucleus and cytoplasm
Using a codon wheel what is AUG?
Methionine
Where must an mRNA attach before protein production can begin?
mRNA must attach itself to a ribosome
Using a codon wheel what amiod acid is UUG?
Leucine
During translation, the strand from mRNA combines each 3 letters into amino acids. What would the amino acids be in this strand (A-U-G-G-C-C-U-G-G-A-C-U-U-C-A)
Met(methionine), Ala(Alanine),Trp(Tryptophan), Thr(Theroline), Ser(Serine)
