Overview Of Protein Synthesis Flashcards
1
Q
RNA
A
Single stranded AU CG nucleus and cytoplasm Many copies Ribose sugar
2
Q
mRNA (messenger)
A
RNA version of the gene encoded from DNA sequence via transcription and may vary in length
Translated into protein by ribosomes “middle man”
3
Q
tRNA (transfer)
A
Delivers amino acids to ribosomes synthesize protein very short only 70-90 base pairs long
4
Q
rRNA (ribosomal)
A
Bonds with proteins to form ribosomes
Varies in length
5
Q
Genetic code
A
20 different amino acid
4 nitrogenous
Sequence of 3 nucleotides codes for 1 amino acid
6
Q
Wobble hypothesis
A
More than one codon could be used to code for an amino acid
This indicates redundancy in genetic code
Minimizes errors that may lead to serious mutation
7
Q
Stop codon
A
Signals the end of translation to ribosome has many sequences
Evidence that organisms descended from one common ancestor
8
Q
DNA
A
Double stranded ATCG only in nucleus Only 1 copy Deoxyribose sugar
