PLEASE HELP ME ASAP!!!!!!!!!! EVEN IF YOU DONT GIVE ME THE ANSWER TO THIS QUESTION AT LEAST HELP ME UNDERSTAND HOW TO GET THE AN
SWER!!!!!!! The structures of the amino acids lysine and aspartic acid are shown:
The tertiary structure of a given protein contains an interaction between aspartic acid and lysine. Discuss the effect that replacing the lysine with another amino acid may have on the tertiary structure and function of the protein. Predict which types of amino acids would cause the least amount of change to the tertiary structure of the protein and explain why.
Replacing lysine with aspartic acid is really a change in the primary structure (the sequence of the amino acids - think in a chain). But because they are really different amino acids, the effect is much more profound and will affect the tertiary structure of the protein.
Lysine has a basic, positively charged side chain. Aspartic acid has a negatively charged carboxyl group for its side chain. So, they are two very different amino acids.
Since the tertiary structure of a protein is a result of the interactions of the various interactions of the amino acid side chains, you have to think about what a swap of a basic positive amino acid with a negatively charged amino acid could cause.
For example, if the lysine side chain interacted in ionic interactions (i.e. attraction to a negatively charged amino acid), if you swap it for aspartic acid which is negatively charged it will now repel the other amino acid's side chain and that would disrupt the tertiary structure of the protein. It would also likely cause disruption to the quaternary structure as well.
If this change was in an important part of the protein (e.g. the active site of an enzyme) then it would likely disrupt the proper functioning of this protein.
If you wanted to make the least amount of change to a protein by making a mutation to that lysine amino acid, you would choose other basic amino acids which are histidine and arginine.
It is choice B. Haploid cells contain one copy of genetic information. (ex sperm, egg) Diploid cells contain two copies of the genetic information. (ex muscle, bone brain, eye, etc.)
Elevation is the altitude (height) above the sea level. The Florida being at the height of less than 100 feet is its elevation.
The major factor that affects the climate of that region is its elevation.as the elevation increases i.e. the height of the place from sea level increases the temperature of that place lowers.
For every 1 kilometer rise in elevation the temperature decreases by 6.5 degree Celsius. Hence, Jena is concerned about the elevation.
