What is the function (Job )of mRNA?
It carries amino acids to the growing protein.
It makes up the ribosomes and provides the site for protein synthesis.
It is transcribed from the DNA and carries the information to the ribosome.
If a nucleic acid contains the bases AUU GCA UCG, it would most likely be?
Messenger RNA
DNA
A gene is:
A segment (piece) of DNA that codes for a specific protein.
An RNA sequence that carries information to produce codons and anticodons.
a DNA nucleotide sequence that carries information to produce an amino acid.
Given the DNA sequence CAC-GTA-TGC-AAA-ATT, use the table above to describe the order of the amino acids.
Valine – Proline -- Threonine--Leucine and is incomplete.
Valine - Histidine – Threonine -- Phenylalanine and is complete.
Histidine -Valine – Alanine – Lysine -- Isoleucine and is complete
What is the form ( shape) of mRNA ?
Double Helix
Single Strand
Double strand
Name the process that makes mRNA
transcription
translation
replication
A group of 3 bases is called a ?
nucleotide
anti-codon
codon
A mutation occurs in a gene that changes one mRNA codon from UCC to UCG. No other codons were affected by the mutation. Which of the following statements is true? (Use the codon chart)
This is a point mutation and there will be no effect on the final protein structure
This is a point mutation and the final protein structure will be affected
This is a frameshift mutation and the final protein structure will be affected
A mutation that involves the insertion or deletion of one nucleotide is called a(an)
frameshift mutation
substitution.
Genetic changes can occur as a result of exposure to chemicals and radiation, and exposures in the womb or early childhood may affect health later in life. This is due to:
changes to production of proteins.
genes turned on or off.
Both answers
All of the following are considered high risk for changes (mutations) in DNA Except:
smoking
exposure to lead
exercising daily
