The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome.
Nitrogen base sequence for the start codon is AUG.
Answer:
The correct answer is "It prevents spontaneous muscle's contraction".
Explanation:
Muscle contraction is produce by the interaction of actin and myosin filaments. Basically, myosin binds to the active sites of actin, which produces a protein complex (known as actomyosin) that allows that the filaments slide past each other and generate a contraction. When troponin and tropomyosin block the active sites of actin prevents spontaneous muscle's contraction, because a nervous impulse is needed to remove the inhibitors and that myosin starts the contraction.
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
