DNA structure/replication
A double helix with a sugar-phosphate backbone and nitrogen base pairs
DNA
A set of 3 nucleotides on mRNA
Codon
A single base change (substitution); may be silent (no effect), missense (changes amino acid), or nonsense (creates a stop codon).
Point mutation
When does Crossing over occur?
Prophase I
1000ml is called what?
A liter
A section of DNA (and thus of a chromosome) that has instructions to code for a protein is
A gene
A chain of amino acids that can bind to other polypeptides and fold into a protein
Polypeptide
Insertion or deletion of a base that shifts the reading frame, often resulting in nonfunctional proteins.
Frameshift mutation
What does Meiosis produce?
What is 12x12
144
The macromolecule that holds our genetic material
Nucleic Acid
What is the role of the Ribosomes?
Assemble amino acids into polypeptide chains.
Factors that cause mutations (radiation, chemicals, UV light).
Mutagens
Why is genetic variation important?
Ensures species survival by increasing adaptability to environmental changes
Who is playing in SuperBowl 60?
The New England Patriots and Seattle Seahawks
Ensures genetic information is accurately passed to new cells.
What are the 3 stop Codons and the 1 start Codon
UAA, UAG, UGA and AUG
What kind of mutation is Sickle Cell Disease?
Point Mutation
What is a Karyotype?
An organized profile of a persons chromosomes
How many bones are in the Human body?
206
What are the 3 key enzymes in DNA Replication?
Helicase, DNA Polymerase and Ligase.
DNA → mRNA (occurs in the nucleus, uses RNA polymerase) and mRNA → Protein (occurs at the ribosome, involves tRNA bringing amino acids).
What is a Translocation mutation?(Chromosomal mutation)
What is the difference between Meiosis I and Meiosis II?
Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids.
Who was the 35th President of the United States?
John F. Kennedy
