Mutations 1
When a incorrect nucleotide is put into a DNA molecule.
What is an insertion mutation?
When a segment of a chromosome is lost and not repaired
What is a chromosome deletion mutation?
These are composed of amino acids.
What are proteins?
These molecules are enzymes, transporters, messengers, and are structural.
What are proteins?
Vitamins are this type of nutrient.
What are micronutrients?
When a nucleotide in DNA is changed.
What is a mutation (in DNA)?
When a segment of a chromosome breaks off and is reattached backwards.
What is an inversion mutation in a chromosome?
These contain long chains of H-C-H.
What are lipids or fats?
These molecules provide rapid energy for cells.
What are carbohydrates, simple sugars?
Food energy is measured in these.
What are calories?
What is thymine?
What is a nucleotide in DNA?
When a pair of almost identical chromosomes do not separate during reproductive cell production.
What is nondisjunction?
DNA and RNA are both this type of molecule.
What are nucleic acids?
These molecules make proteins.
What are nucleic acids?
These organic molecules contain the most energy per gram.
What are lipids?
When a nucleotide in DNA is lost or removed when it should not be.
What is a deletion mutation?
When part of a chromosome breaks off and reattaches to a different chromosome.
What is a translocation mutation?
Polysaccharides are composed of many, 100s or 1000s, of these.
What are simple sugars?
These molecules are made of nucleotides.
What are nucleic acids?
Our red blood cells require this to transport oxygen, O2.
What is iron?
When nucleotides for a stop codon are put in DNA where they do not belong.
What is a nonsense mutation?
What type of mutation can affect 100s of genes and proteins?
What is a chromosome mutation?
These molecules store energy, are insulators, and are structural.
What are lipids (or fats)?
These molecules can dissolve most types of organic molecules.
What is water, H2O?
Protein and carbohydrates are both this type of nutrient.
What are macronutrients?
