Suppose you discover a new form of a nucleic acid, XNA. Like DNA, it is double-stranded. You are interested in its mode of repli
victus00 [196]

Answer:

A: Unlike DNA, XNA replicates conservatively

Explanation:

<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>

In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.

Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.

In rabbits, black fur (B) is dominant to white fur (b). A purebred black furred male is bred with a female that had the recessiv
ValentinkaMS [17]

Answer:

All the offsprings will be black-furred (Bb)

Explanation:

This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.

According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:

BB - B only

bb - b only

Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:

Bb, Bb, Bb, Bb

All Bb (heterozygous) means that all of the offsprings will be black-furred.
