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 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 the 3 types of point mutations
substitution, deletion and inserting
What is the shape difference in DNA and mRNA?
DNA is a double Helix, RNA is a single stranded or helix.
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 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.
when a portion of the chromosome is taken out, which can make that chromosome less functional.
deletion
What are 2 processes or steps of protein synthesis called?
Transcription and Translation
Transcription takes place between what?
DNA and mRNA
Transfer RNA
What must DNA to do first to make an mRNA strand?
a portion of the chromosome is flipped in the opposite direction, which may or may not cause disease.
inversion
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?
Anticodon and amiod acid
How many amino acids are there?
20
a portion of the chromosome is copied more than once, resulting in extra genetic material.
duplication
Where is DNA and mRNA located at?
DNA is found in the nucleus, mRNA is found in the nucleus, cytoplasm, ribosome
Using a codon wheel what is AUG?
Methionine or start codon
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
a portion of a chromosome breaks off and reattaches to another chromosome.
translocation
