DNA
What does DNA stand for?
Deoxyribonucleic Acid
What are chromosomes?
strands of tightly wound DNA
What is a genotype?
the genetic make-up of an individual
What is a trait?
Characteristics that are past down from your blood-line.
What is a gene?
sections of a chromosome that carry the code for a particular trait.
What is DNA?
A double helix molecule
What do most eukaryotic chromosomes include?
Packaging proteins called histones
What is the opposite of a genotype?
Phenotype
Is inheriting reading ability possible?
No
What is an alternate form of a gene?
An allele
What do DNA molecules include?
Sugars (deoxyribose), nitrogenous bases (Adenine pairs with Thymine; Cytosine pairs with Guanine), and phosphates.
How many chromosomes do you receive from each of your parents?

What is an example of a genotype?
Bb
Do dominant traits always hide the recessive traits?
Yes
What is the relation between DNA and genes?

ATTCGGCAC
What are chromosomes made of?
Protein and a single molecule of deoxyribonucleic acid
What are the three genotypes?
PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive)
Can characteristics that are acquired through environmental influences, such as injuries or practiced skills be inherited?
No
Name one historical contributions and significance of discoveries related to genetics.
The discoveries of Rosalind Franklin (provided X-ray diffraction images), James Watson and Francis Crick (proposed the double helix or spiral staircase structure of the DNA) helped lay the foundation of the DNA, or Gregor Mendel- Father of Genetics
