Upcoming test to be labeled later Flashcards
Definition:
An important body structure made from atoms
Proteins
Definition:
Composed bundles of cells, which make up small strands
Muscles
The two proteins in muscle cells are:
Actin and myosin
What is the job of actin and myosin?
Help the muscles by grabbing each other and pulling so the muscle fibers can contract
Fill in the blank:
Exercise and diet play a role in ________ _______
building muscle
Fill in the blank:
_______ has a large influence on musculature.
Exercise
Fill in the blank
Diet has a small influence on __________.
Musculature
If the offspring is heavily muscled what might the parents be?
Extra muscled or medium muscled
If the offspring is typically muscled what might the parents be?
Both of them will be typically muscled
How many chromosomes are passed down to the offspring during the fertilization of the egg and sperm?
30 chromosomes to each
What is called when muscle cells have two of each chromosome?
Karyotype
What specific region of the chromosome controls how specific protein is made?
Gene
What is the function of myostatin?
To fit into the cell receptors of the cell
Fill in the blank:
When the myostatin fits correctly into the cell receptor ________ _________ ________.
Muscles develop typically
Different forms of protein have different variations, like _____ ______ _____ _______ ________.
Extra-big or typically muscled
Different versions of a gene are called _______.
Alleles
What determines the proteins that gets produced, which leads to the phenotype?
An animal genotype
The structure of a gene has a different Helio causing different shaped myosin protein. What is the result in those animals phenotypes?
Heavily muscled
Partial myostatin protein does not fit into receptors on cells, so no message is sent causing want to happen?
Animals to have extra big muscles
The mix of partial and complete myostatin proteins results in _________ _________.
Medium-muscled
The physical structure that carries genetic information
Genetic material
The instructions stored in genes for making specific proteins
Genetic instructions
What does heterozygous mean?
Having two different alleles for a particular gene
What does homozygous mean?
Having two of the same alleles for a particular gene
