First reason Viruses don't have any cells, like living organisms do. second reason is Viruses can't produce new proteins, DNA, or RNA and therefore are unable to reproduce on their own. third reason Viruses have no metabolic activity. They don't use or convert energy and have no ongoing interior processes
With continued symptoms of nerve agent exposure often you should self inject after 5 minutes. As long as one is experiencing symptoms associated, one should administer and ATNAA injection every 5 minutes. However, it is important to seek medical guidance before administering more than 3 ATNAA injections.
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.
If they are both heterozygous, then they both have alleles Bb.
Using a Punnett square, we draw the following:
B b
B BB Bb
b bB bb
Since B is dominant, so only bb will give white fur, i.e. 1 out of four is expected to give white fur.
Probability is therefore 1/4.
In all organic molecules, all carbon atoms always have four covalent bonds. organic compounds, carbon atoms are most likely to bond with hydrogen, oxygen, nitrogen, sulfur, and halogens such as chlorine. Hydrogen with one valence electron forms a single covalent bond.
