Answer:
(D). true-breeding.
Explanation:
True-breeding can be defined as a type of breeding, in which parents produce offspring with same phenotype as present in parents. In plants, true-breeding takes place only when their is self-fertilization.
These true-breeding organisms or varieties have a pure genotype (genetic makeup for a trait) and they show only a certain phenotype (physical expression of that trait).
Thus, the correct answer is option (D).
Answer:
The correct answer is - Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Explanation:
According to the question, the life span differences were independent of reproductive investment, on the basis of this experiment, it is clear that the sexual gametes or egg which is a reproductive investment are independent of the lifespan of a female.
The life span of females could be slow growing or not but it will not affect the production of the gametes or eggs. Eggs production is dependent upon hormones produced.
Answer:
Its genetically identical to its parent
Explanation: Vegetative reproduction occurs asexually and involves only one parent. The offspring of vegetative reproduction is genetically identical to its parent.
Answer:
AUG CAG UUC UUG CGC GAA UAA GCA AU
Explanation:
tRNA pairs with mRNA to make a chain of amino acids that form a protein, through the process of translation. The anti-codons in the tRNA are complementary to the codons in the mRNA. Through the rules of complementary base pairing, A always pairs with T/U and G always pairs with C.
T/U is because in DNA, the base is thymine (T), but in RNA, the base is uracil (U).
Therefore, wherever you see a U in the mRNA sequence, the complementary tRNA is A. Whenever you see an A, the complementary tRNA is U. Whenever you see a G the complementary base is C, and whenever you see a C, the complementary base is G.
