Studied by 13 peopleWhat process is nucleus involved in?
Transcription
How is the nucleus involved in Protein Synthesis?
Where is DNA is transcribed
What process is mRNA involved in?
both
How is mRNA involved in Protein Synthesis?
mRNA is produced from DNA in transcription. mRNA is then transcribed into amino acids
What process is the ribosome involved in?
translation
How is the ribosome involved in Protein Synthesis?
where mRNA is translated to amino acids
What process is tRNA involved in?
translation
How is tRNA involved in Protein Synthesis?
the link between mRNA and the chain of amino acids
How is DNA involved in Protein Synthesis?
The original code that is translated and transcribed
What process is the cytoplasm involved in?
Translation
How is the cytoplasm involved in Protein Synthesis?
where translation occurs
What is an intron?
DNA that codes for nothing
What is an exon?
DNA that contains important information
Do introns or exons exit the nucleus to move onto translation?
Exons
DNA traits
sugar = deoxyribose
phosphates present = yes
letters of nitrogen bases = A,T,C,G
complementary base pairs = A-T, C-G
number of strands = 2
RNA traits
sugar = ribose
phosphates present = yes
letters of nitrogen bases = A,U,C,G
complementary base pairs = A-U, C-G
number of strands = 1
What process is DNA involved in?
transcription
What is the difference between codons and anticodons?
Codon - 3 letter nucleotide sequence on mRNA that codes for an amino acid
Anticodon - 3 letter nucleotide sequence on tRNA that binds to and “reads” a specific mRNA sequence
What is the role of mRNA during protein synthesis?
complements DNA, travels from nucleus to cytoplasm and directs synthesis of protein, !!!codes for amino acids!!!
What is the role of rRNA during protein synthesis?
binds with proteins to make ribosomes
What is the role of tRNA during protein synthesis?
transports amino acids that match the mRNA code to the ribosome
What is point mutation/substitution?
one letter gets switched (1 potential different amino acid)
What is insertion?
one letter gets added to the code, all amino acids after the mutation are changed
What is deletion?
one letter gets removed from the code, all amino acids after the mutation are changed
