Bennett Biology - DNA and Protein Synthesis 2

messenger RNA

What kind of RNA is made from DNA in the nucleus?

ribosome

Make proteins or assemble amino acids into proteins.

translation

The process of assembling proteins.

protein synthesis

Another term for translation.

codon

three nucleotides on a mRNA molecule

anticodon

three nitrogen bases on a tRNA molecule

3

How many nitrogen bases are needed to make a codon? And an amino acid?

4

How many codons are there given the following DNA strand? A T C G C G A T C G A T

2

How many complete codons are there in the following RNA Strand? A U G C G G A

transcription

Which comes first, transcription or translation

RNA

Is this DNA or RNA? A U C A G C C A A U U C

enzymes

Speed up reactions

ase

Enzymes end in these three letters.

RNA polymerase

This enzyme helps split DNA apart and make RNA.

mutation

change in the DNA

frame shift mutation

Occurs when a nucleotide is added or removed which causes a change in the codon which causes a change in the amino acid(s). This is the worst type of mutation because it changes many amino acids.

substitution mutation

When one nitrogen base is switched with a different nitrogen base. This may or may not be a bad mutation since there are several codon possibilities for a given amino acid.
