Answer:
Translation will not occur.
Explanation:
The start codon is responsible for the initiation of translation in both prokaryotes and eukaryotes. AUG is the start codon in both which code for methionine in eukaryotes and formyl methionine and prokaryotes.
Therefore if the starts codon becomes mutated than the tRNA would not able to recognize the initiation codon and no methionine would be added as the first amino acid so the translation process might not start and no protein forms. Then the ribosome scans further for the next start codon to start translation.

Explanation:
The cross of a pea plant with round seeds (RR) with another pea plant with wrinkled seeds (rr) is shown as under :
P RR x rr
F1 Rr Rr Rr Rr
It is clear from the cross above, all the 4 probable progenies in filial 1 (F1) generation will be heterozygous with Rr genotype. Not even a single progeny will have homozygous recessive genotype which is responsible for producing wrinkled seeds. Also, even though the genotype of the progenies will be Rr not RR yet phenotypically they all will have round seeds i.e. they will show dominant trait. The reason behind it is that one of the alleles R which is responsible for dominant trait will mask the expression of recessive allele r. So, wrinkled phenotype which is a recessive trait will not be observed in any of the progenies.
BTX or batrachotoxin is a type of steroidal alkaloid which was first derived from the skin of Dendrobatidae or poison dart frogs. This neurotoxin prevents the muscle and nerve cells from transmitting electrical signals. The toxin permanently blocks electrical signal transmission from the nerves to the muscle by binding and inactivating the sodium channels.
The answer will be b: because every one is saying something about it.
