Module 3A Flashcards
What happens in the Mitochondria ?
Respiration that will provide energy for important life processes.
Why do the Liver cells have large numbers of mitochondria?
They require a lot of energy for metabolic reactions.
Why do the muscle cells have a lot of mitochondria?
They require a lot of energy for contractions and movement.
Where are chromosomes found?
In the nucleus.
What are Chromosomes
Long strands of coiled up DNA
Describe three points about the structure of DNA
1) two long strands coiled to form a double helix
2) each strand contains chemicals called bases that cross link across the strands
3) it contains genes
What are genes?
A section of DNA that contains it’s own sequence of bases
Because each gene has a different sequence of bases, what is the result overall?
A unique protein will be coded for.
A gene codes for a…
specific protein
What is every single protein made from?
A chain of amino acids
Every single protein has its own number and order of amino acids. What does this mean?
Every single protein will have a different shape and therefore different function.
Every single protein has a different shape and function, why is this?
Every single protein has a different number or order of amino acids.
3 bases makes …
1 amino acid
1 amino acid is made from…
3 bases
What will the order of bases in a gene determine?
The order of amino acids in a protein.
