<span>Additional facts:
A test cross between an organism whose genotype for a certain trait is unknown and an organism that is homozygous recessive for that trait so the unknown genotype can be determined from that of the offspring.
Answer:
You'd use it when you wish to see if the one that you think is a homozygous dominant is a purebred, because if you did get a recessive offspring then it proves that the animal is a heterozygous and not a purebred.</span>
RNA has Uracil instead of Thymine. All the other three bases also occurs in RNA, adenine, guanine and cytosine. Therefore a ATA DNA codon will be transcript to UAU by RNA. Both Thymine and Uracil have the same role in however have minor chemical differences.
Two examples of how the biosphere supports life is by reducing the amount of harmful radiation to reach the surface of the earth. It also gives oxygen for animals to breathe
Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.
What is enzyme activation of pathogen?
Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.
- TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
- The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
- The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
- Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.
Hence, the correct answer is option A

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
