What is a function of a gene? |
|
Definition
carry instructions for synthesizing protiens! |
|
|
Term
|
Definition
occurs in the nucleus When RNA polymerase enzyme binds to th promoter, located at teh start site of a gene, and makes a Mrna that is complementary to the dna gene. RNA differs from DNA in that the sugar is RNA is ribose(not deoxyribose) and the nitrogenous bases are adenine, cytosine, and uracil (**No thymines in RNA)

Definition
occurs in the cytoplasm o eukaryotic cells and involves mRNA, ribosomes, and trna. Messenger RNA carries the code from the DNA, and ribosomes are the site where amino acids are assembled to synthesize protiens. Transfer RNA(tRNA) carries amino acids, which bind to triplet nucleotide sequences on the mRna called codons.

Mutations are change to the DNA sequence that can affect protein structure and function. What is a nuetral mutation. |
|
Definition
| changes to the DNA that do not result in a different amino acids being incorporated. INsertions or deletions of nucleotides can result in frameshift mutations that change the protein drastically. |
