What is DNA?
The blueprint for all life.
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 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 a structure difference in DNA and mRNA?
DNA is a double Helix, RNA is a single Helix.
A deoxyribose sugar in DNA and a ribose sugar in RNA
nitrogen bases U in RNA and T in DNA
What anticodons 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?
mRNA and tRNA
What is the monomer of a protein?
Amino acids
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 goes from what to what?
DNA and mRNA
Transfer RNA
What type of bond is formed between amino acids?
Peptide bonds
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 codes for the amino acid
codon on mRNA
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 /ribosome
Using a codon wheel what is AUG?
Methionine
anticodon
Using a codon wheel what amiod acid is UUG?
Leucine
During translation, the strand from mRNA combines each 3 letters of amiod acids to form into polypeptides. What would the peptides 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)
