In cold temperatures, phospholipid bilayers with saturated fatty acid tails are more rigid, while phospholipid bilayers with uns

inessss [21]

Answer:

The reason why, in cold temperatures and depending on the type of fatty acids, the phospholipid bilayer is less or more fluid is due to the different molecular interactions that occur between the tails of both types of fatty acids. the unsaturated - which determines the fluidity of the cell membrane.

Explanation:

Temperature and saturation of fatty acid tails are two factors that affect the fluidity of the phospholipid bilayer in cell membranes.

Under normal conditions, low temperatures decrease the fluidity of the phospholipid bilayer, since it decreases the kinetic energy and increases the molecular interactions, which increases the stiffness.

However, unsaturated fatty acids - those that contain double bonds in their molecules - have a configuration that allows their tails to be more separated in their arrangement in the bilayer, which avoids the increase in molecular interactions and maintains to a certain extent the membrane fluidity, despite low temperatures.

Identify all the amino acid-specifying codons where a point mutation (a single base change) could generate a nonsense codon.

Murrr4er [49]

Answer:

Glutamic Acid (Glu): codons GAA, GAG

Glutamine (Gln): codons CAA, CAG.

Lysine (Lys): codons AAA, AAG, UCG

Serine (Ser): codons UCA, UCG

Leucine (Leu): codons UUG, UUA

Tyrosine (Tyr): codons UAC, UAU

Tryoptophan (Trp): codon UGG

Arginine (Arg): codons CGA, AGA

Glycine (Gly): codon GGA

Cysteine (Cys): codon UGU

Explanation:

Non sense codons are: UAA, UAG, UGA. Then following the genetic code (see attached file) a single base substitution in any of the codons indicated in the answer could generate a stop codon. This single base substitution might happen in the first, second or third base of the codon.

Nataly_w [17]

Answer:

The correct answer is "Red shift"

Explanation:

Blue shift: When the source and observer approach one another, the evident frequency increments or apparent wavelength diminishes. Here the Doppler shift is positive. This is known as blue shift.

Red shift: When the source and observer move away from one another, the clear frequency diminishes or apparent wavelength increments. Here the Doppler shift is negative. This is known as red shift.
