DNA
This is the shape of a DNA molecule called?
What is the double helix?
This is the meaning of when a cell "replicates" its DNA
What is making an exact copy of the DNA?
This is the part of the cell where transcription takes place.
What is the nucleus?
This is the location of translation
What is the ribosome in the cytoplasm?
Fill in the blank for the Central Dogma of Biology:
DNA -> _________ -> Protein
What is mRNA?
what is the nucleus
If an original DNA strand reads A-T-T G-C-A, this will be the new complementary DNA strand be after replication
What is TAA CGT?
During transcription, DNA is copied into this single-stranded messenger molecule
What is mRNA?
This special 3-letter code on mRNA tells the ribosome where to start building the protein
What is AUG or START Codon?
A 3-letter sequence on mRNA that codes for one amino acid is called a ________
If one side of a DNA strand is T-A-C, this would be the complemtary side.
What is ATG?
This molecule unzips the DNA strand during replication
What is helicase?
Transcribe this DNA strand into an mRNA strand: T-A-C C-T-T
What is AUG GAA?
This helper molecule brings amino acids to the ribosome
What is tRNA?
Name TWO differences between DNA and RNA.
What are
DNA has deoxyribose sugar, RNA has ribose sugar.
DNA is double-stranded, RNA is single-stranded.
DNA has Thymine (T), RNA has Uracil (U).
DNA stays in the nucleus, RNA leaves the nucleus.
These four nitrogen bases are found in DNA.
What are A, T, C, G?
This part of the cell is the location for DNA replication
What is the nucleus?
This base replaces Thymine in RNA.
What is Uracil?
These building blocks of proteins that connect together like beads on a necklace
What are Amino acids?
Name TWO important jobs proteins do in your body.
What are building muscle, breaking down food with enzymes, or fighting viruses?
DNA is made of repeating building blocks called nucleotides. These THREE parts make up a nucleotide
What are a Phosphate group, a Sugar (Deoxyribose), and a Nitrogen base?
This is the reason cells make a copy of its DNA before it divides
What is so that each new cell gets a full set of DNA instructions?
The mRNA leaves through these lttle doors.
What are the nuclear pores?
Translate this sequence CAUUCAAUGCCU as if you were a ribosome.
Put these 4 steps of Protein Synthesis in order from FIRST to LAST:
A. tRNA brings amino acids to the ribosome
B. mRNA leaves the nucleus through a nuclear pore
C. DNA is transcribed into mRNA in the nucleus
D. Ribosome binds to the start codon (AUG)
What is C-> B -> D->A?
