DNA: life's code. =. What does DNA mean?. DNA=. D eoxyribo- N ucleic A cid. _____________. DNA looks like. A ladder. twisted. ...that has been __________ over and over. It's called a "________________". Double helix. What's its function?.
...that has been __________
over and over.
It's called a
DNA makes up genes that determines the ______ of all living things….such as:
Eye color, skin color, texture, freckles, hair color, style…etc
Found in the __________ of all cells
Each rung is a combination of ______ ________________ bonded together.
The Nitrogen bases are:
C = CYTOSINE
G = GUANINE
T = THYMINE
A = ADENINE
2 nitrogen bases
DNA code work?
“C” bonds ONLY with “___”
This goes on for the entire length of the DNA molecule, which consists of __________ of nitrogen bases.
The ____________________ in DNA will determine what the trait is.
sequence of letters
For example: Lets take a look at the letters of the alphabet…
If you change the letters to
“L O W”
it no longer means…
“O W L” means
“A predatory bird”
“A predatory bird”
Since DNA consists of billions of nitrogen bases, the amount of variation among organisms is HUGE. If you change only one letter, the entire code will be changed, and therefore the organism will be different!!
A gene is a
________________________that codes for one __________________.
There are about __________ genes in an entire DNA molecule
RNA is a “__________” molecule. It helps carry the DNA code to the __________ so it can make the protein.
DNA contains the code for what protein will be made by the cell
carry the DNA code to the ribosome
A random change in the DNA code
A chromosomes is made up of DNA, which is consists of about 30,000 genes
bc it’s the sequence of nitogen bases that makes us different
SIDE PARTS RUNG PARTS
nucleus, chromosome, genes, and DNA?
How are they related?
How are they related? _____________________________
A MUTATION is any _________________ in copying the DNA message.
CHANGE = WRONG ______________
A wrong base in the DNA gives the cell the wrong __________________.
If a cell has the wrong message, the wrong type of ________________ is made.
If the wrong protein is made, the wrong ________________ may appear.
__________________: Any agent that can cause alterations to DNA
Any trait that interferes with the ______________________
and _________________ of an organism.
Any trait that enhances an organisms ability to______________________
and _________________ in its _____________________.
