Hardy-Weinberg equilibrium in a concept that states that a population's genotype frequencies stay the same over time as long as certain conditions are met. There are five conditions needed for a population to stay in equilibrium. Populations that meet these conditions are not evolving. The conditions are that the population must be very large, so no genetic drift can occur; no emigration or immigration, so no gene flow can occur; no mutations can occur; mating must random, so no sexual selection can occur; and there must be no natural selection, with all traits equally aiding survival. However, all these conditions are rarely met by real populations.
Answer/Explanation:
If a protein has a quaternary structure it is formed when many subunits get together.
- true. The quaternary structure of a protein is the final stage in its assembly, when structures from multiple polypeptides come together, forming a multi-subunit protein (e.g. a dimer if 2, a trimer if 3 and so on)
Monomers form the secondary structure of proteins.
- false, they form the tertiary structure
The charges on the functions groups of the amino acids creates the beta pleated sheets and alpha helix structures that are the secondary level of structure in proteins.
- false, it is mostly the peptide backbone that causes the alpha helices and beta sheets to form
The order of the amino acids is the primary structure of proteins. - true. The amino acid sequence linked together by peptide bonds is the polypeptide sequence, which then forms increasingly complex structures when folded.
The tertiary structure of proteins is formed when the B sheets and alpha helices organize themselves into a more complex shape. - true. These complex structures can further interact with one another to form increasingly organized domains. The amino acid side chains possess different properties that form different bonds with one another.
The primary structure of proteins is formed from the amino groups on the proteins. - false, the primary structure is formed by the sequence of amino acids in the chain, determined by the mRNA sequence from which the protein is synthesised.
Answer:
Calcium is a mineral that people need to build and maintain strong bones and teeth. It is also very important for other physical functions, such as muscle control and blood circulation.
