Answer:
a) both parents
Explanation:
autosomal recessive means that both copies of the "no tail" allele must be inherited in order to produce a dog with no tail, therefore the answer is both parents
Answer:
it is expected that the mutation results in a reduced initiation of translation and thereby decreasing the level of the protein A, while it does not change the level of mRNA A
Explanation:
Translation in bacteria starts with the formation of the initiation complex which is composed of the small ribosomal subunit, the messenger RNA (mRNA), initiation factors and the initiator transference RNA (tRNA) containing N-formyl-methionine. The small ribosomal subunit binds to a polypurine stretch of variable length in the mRNA called 'the Shine-Dalgarno sequence'. A mutation in this sequence reduces the affinity of the ribosome for the mRNA, thereby, in this case, decreasing the level of protein A. Since transcription occurs before translation, it is expected that this mutation does not change the level of expression of the mRNA A.

Answer:
Chordates
Explanation:
The notochord is a flexible, rod like supporting structure, running dorsally for almost the whole length of the body. This is a distinctive feature of a chordate / animals with a back bone (vertebral column) Such animals belong to phylum Chordata.
