DNA + Traits
Where do genes come from
they are inherited from parents
What does adenine (A) pair with
thymine (T)
What is the shape of the structure of DNA
double helix
What are traits
characteristics that are inherited (eye color, height, etc.)
what makes up the 'rungs' of the ladder
nitrogenous bases
How is your DNA related to your parents' DNA
it is similar
What are the 4 nitrogenous bases
adenine (A), thymine (T), guanine (G), cytosine (C)
What is a gene
the section of DNA that codes for a specific protein
What is inheritance
genetic information passed down from parent to child
what makes up the 'sides' of the ladder
sugars and phosphates
every living thing
What is the section of DNA that codes traits called (where genes are located)
the coding section
What does most of a cell's work
proteins
Write the other strand of bases for this sequence:
A T T C G A C T
T A A G C T G A
how many nucleotide bases form one codon
3
What does DNA code for
proteins that determine traits
What is a bundle of DNA or genes called
a chromosome
What part of DNA 'writes' the information for traits
the nitrogenous bases
If a section of DNA has 15% thymine, how much adenine will it have
15%
if a section of DNA has 30% thymine, how much cytosine will it have
20%
What is DNA made up of
nucleotides
What is semi-conservative replication
each strand has half old DNA and half new DNA
What are proteins made from
amino acids
What will happen to a cell if all of its DNA is removed
it will no longer be able to create proteins
what are 3 things that could happen if a mutation occurs
the gene could be...
expressed in the wrong cell, unaffected, or permanently broken
