Question | Answer |
---|---|
What is the structure of a nucleotide? | The structure of a nucelotide consists of sugar and one of four bases: Cytosine (C), Thymine (T), Adenine (A), Guanine (G) and a phosphate. |
What is the structure of a molecule of DNA? | A Double Helix. (DNA) a double strand with 2 complementary bases~ |
Where is DNA found in the cell? What does the cell make from the instructions in DNA? | DNA is found within the nucleus of the cell and the cell makes mRNA |
How is DNA copied? When in the cell cycle does the cell make copies of DNA? | DNA is copied by making a replica in smaller DNA regions through a biological process. It makes copies when the cell is about to split/divide. |
What are the complementary base pairs in DNA? | Adenine, Cytosine,Thymine, Guanine |
What are the three types of RNA? Which type of RNA carries instructions from DNA to the ribosome? | mRNA,rRNA,tRNA are the three types. the RNA that carries instructions is mRNA |
What do tRNA molecules use their anticodons for? | They use their anticodons for to recognize other codons and identify them. |
Describe the relationships among the following terms: mRNA, tRNA, ribosome | |
What is a codon? | Three bases on an mRNA molecule that code for a specific amino acid. |
What is the start codon? | AUG is the start codon or aka: MET |
What is the stop codon | UGA UAG UAA |
