level questions: DNA and the production of proteins
| Question | Answer |
|---|---|
| What is a gene? | a section of DNA which codes for making a protein to give you a characteristic |
| What is DNA? | a double stranded helix held together by complementary base pairs |
| what are the four bases that make up the genetic code? | Adenine Guanine Cytosine Thymine |
| Name the two base pairs that make up the genetic code | Adenine + Thymine Guanine + Cytosine |
| What are proteins made of? | many subunits called amino acids linked together in long chains by peptide bonds |
| what does the sequence of amino acids of a protein determine? | the structure and function of the protein |
| What does the DNA base sequence determine? | The amino acid sequence in proteins |
| how is mRNA molecule produced? | when genetic code is copied |
| what is an mRNA molecule? | molecule which carries a complementary copy of the genetic code from the DNA in the nucleus to a ribosome where the protein is assembled from amino acids |
| what happens after mRNA molecule has been produced? | it carries a complementary copy of the genetic code from the DNA out of the nucleus to a ribosome |
| what happens after mRNA molecule carries genetic code to ribosome? | amino acids arrive at ribosome and line up according to sequence of bases on the mRNA |
| what kind of bonds are formed between the amino acids? | peptide bonds |
