Chap 4.5 Vocab

the amino acids and stop signals that are coded for by each of the possible mRNA codons

a section of DNA on a chromosome used for making specific proteins

indicates where protein production should stop

• indicates where protein production should start
• - always AUG
• - codes for the amino acid "Met"

• a nucleic acid similar to DNA in three main ways:
• 1) RNA is a single sttrand
• 2) uses the base uracil instead of thymine
• 3) contains ribose instead of deoxyribose

• made up of three parts:
• 1) sugar- deoxyribose
• 2) phospate group
• 3) nitrogen base
• - adenine
• -guanine
• -cytosine
• -thymine
• 

when information on the DNA is transferred to mRNA

processing information from DNA to proteins

• single rings
• -thymine
• -cytosine

acts as an interpreter molecule

a permanent change in the DNA sequence of a gene or chromosome

when information on the mRNA is used to make a protein

a three nucleotide sequence on a tRNA that is complimentary to a codon

an RNA used as a blueprint for a protein

two strands of DNA twisted together

a three nucleotide sequence on an mRNA that is complimentary to an anticodon and serves as the instructions for making a protein

the process of synthesizing a new strand of DNA

becomes part of the ribosome

• double rings
• -adenine
• -guanine
