1. Answer;
-secondary structure;
Explanation;
Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction. In the beta sheet secondary structure, the polypeptide backbone is nearly fully extended. The R-groups are alternately pointed above and then below the extended backbone.
2. Answer;
- Quaternary structure
Explanation;
-Many proteins are formed from more than one polypeptide chain. The Quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits.
3. Answer;
-Tertiary structure
Explanation;
Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.
The tertiary structure is the structure at which polypeptide chains become functional. At this level, every protein has a specific three-dimensional shape and presents functional groups on its outer surface, allowing it to interact with other molecules, and giving it its unique function.
4. Answer;
Primary structure
Explanation;
-It is the simplest level of protein structure and is simply a sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B. Each chain has its own set of amino acids, assembled in a particular order. For instance, the sequence of the A chain starts with glycine at the N-terminus and ends with asparagine at the C-terminus, and is different from the sequence of the B chain.
Answer:
p = 0.36
q = 0.64
p² = 0.13
2pq = 0.46
q² = 0.41
Explanation:
We need to use the Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1
p: the frequency of the dominant allele
q: the frequency of the recessive allele
p²: the frequency of homozygous dominant
2pq: the frequency of heterozygous
q²: the frequency of homozygous recessive
Here, we know that 328/800 people are homozygous recessive, which means that q² = 328/800 = 0.41.
Then, q = √0.41 = 0.64, and p = 1 - q = 1 - 0.64 = 0.36.
Now, we have p² = (0.36)² = 0.1296 ≈ 0.13 and 2pq = 2 * 0.36 * 0.64 = 0.4608 ≈ 0.46.
The answers are:
p = 0.36
q = 0.64
p² = 0.13
2pq = 0.46
q² = 0.41
Answer: The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
Explanation:
The nurse can follow
these following tips:
For temporary relief
of dryness of mouth from antihistamines:
1. the patient can
chew on sugarless gums
2. the nurse can let
the patient have bits of ice melt in their mouth
3. or the nurse can
give a saliva substitute
If dryness of mouth
does not go away after 2 weeks, seek doctor’s help.
