RNA
The monomer (building block) for RNA is a(n):
nucleotide
Where does transcription occur?
Inside the nucleus
Where does translation occur?
at the ribosomes
How many bases make up a codon?
3
Which form of RNA is associated with the "Codons"?
mRNA
RNA stands for
Ribonucleic acid
In Transcription, _______ is being converted into __________.
DNA to mRNA
In translation, _________ is converted into _______________.
mRNA translates into amino acids
How many codons exist in the genetic code table?
64
Which form of RNA is associated with the "Anti-codon"?
tRNA
In RNA, Uracil replaces this base from DNA
Thymine
Non-coding segments of RNA:
Introns
The "bond" that joins amino acids together.
Peptide
How many amino acids exist within the genetic code table?
20
Another name for protein.
polypeptide
What are the (3) forms of RNA?
mRNA, rRNA, tRNA
Coding segments of RNA:
Exons
What role does tRNA serve in Protein Synthesis?
Delivers amino acid to the protein chain using anti-codons.
How many "stop" codons exist within the genetic code table?
3
Name two different types of mutations that can occur.
Substitution, deletion, insertion
What is structurally different about RNA in comparison with DNA?
1. RNA is single stranded (smaller)
2. RNA contains Uracil
3. RNA contains Ribose sugar
*Daily Double* Transcribe the following DNA sequence into mRNA:
AAG TTT ATG GCA CTC AAT
UUC AAA UAC CGU GAG UUA
*Daily Double* Translate the following mRNA sequence into the amino acid sequence:
UCA AUA AUG GAU CGC UAG
SER-ILE-MET-ASP-ARG-STOP
What is the "start" codon?
AUG or MET (methionine)
Describe what can happen to the "protein" as a result of a genetic mutation.
Mutations can cause different amino acids to be coded for or missing from the polypeptide chain. This changes the structure and function of the protein being built which can impact living organisms in various ways.
