Answer:
b. thick wall.
Explanation:
Endospore is a structure formed by some bacteria, that help them survive unfavourable conditions (e.g. lack of nutrients). This survival strategy of some bacteria (usually Gram+ bacteria) help them stay dormant for a while, until stressful conditions stop. A thick wall composed of many layers (exosporium, spore coat, spore cortex, core wall) of the endospore is what provides resistance to different stressful chemical and physical factors such as UV radiation, temperature, chemical damage etc.
Answer:
Explanation:
This is evident that all enzymes are proteins but not all proteins are enzymes. The specific activity can be define as the number of enzyme units per milliliters that is divided by the available concentration of the proteins typically in mg/ml. Thus the value of the specific activity can be measured in units/mg.
In others words this can be said that how much enzymes units can be found in the 1 mg of the total protein. So in the total concentration of the proteins the estimation of the enzyme units is possible. Thus protein concentration is necessary for calculating the number of the enzyme units.
<span>The answer is
c. .mitochondrion</span>
Answer:
The correct answer is -
A. a, c, g
B. e, b, f & d
Explanation:
Part A- the options a, c, g are the options that show mutation or replacement by a single base change
a) Phenylalanine: UUU UUC
Leucine: UUA UUG
Only one base change
c) Alanine: GCU GCC GCC GCG
Thr: ACU ACC ACA ACG
only one base change
g) Prolin: CCU CCC CCA CCG
Serine: UCU UCC UCA UCG
Part B:
All other replacements will not be consistent with the Genetic Code if single base substitutions occur in option e, b, f & d
