Answer:

Explanation:

The objective is to conclude if the statements are true or false based on facts.

1)\text{ Turtles and leopards all have four limbs and an amnion.  } True

2) \text{The common ancestor of lamprey and lancelets had a vertebral column. } False

This is because their ancestor is a Chordate who doesn't have a vertebral column but a notochord.

3) True

\text{Frogs are the sister taxa of turtles and leopards because they are more }

\text{related to a common ancestor.}

4) \text{Leopards and bass are more closely related than turtles and bass}  False

This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).

5) \text{The taxon that shares the most recent common ancestor with frogs is the bass.} False

The taxa of turtles share a more common ancestor with frogs compared to bass.

6) \text{Leopards and lancelets have no common ancestor. } False

The common distant ancestor for leopards and lancelets is known as  Chordates

I believe the correct answer among the choices listed above is the last option. Plants seemed to evolve in the order of bryophytes, gymnosperms,angiosperms. Bryophytes are mosses that lack vascular tissue. Gymnisoerm do not have seeds but have vascular tissue. Angiosperms have flowers and seeds for mating.

The dicer enzyme processes dsRNA and forms siRNAs, which suppress the expression of target genes by cutting mRNA. 1) siRNA 2) RNA.

<h3>What are siRNA fragments?</h3>

siRNA means small interfering RNA. This is a silencing RNA molecule involved in the RNA interference mechanism, intervening in the expression of a specific gene.

siRNAs are complementary double-stranded RNA molecules composed of about 20-21 nucleotides. siRNA originates from a long double-stranded RNA (dsRNA).

The dicer enzyme cuts dsRNA molecules and produces siRNA. siRNAs suppress the expression of target genes when cutting messenger RNA.

siRNAs suppress the expression of target genes by cutting the complementary messenger RNA (mRNA) into two halves. This is accomplished by the interaction of the siRNA with the RISC complex (RNA-induced silencing complex).

The two mRNA halves are later degraded by the cellular machinery, leading to the suppression of the gene expression.

siRNAs also participate in other pathways related to RNAi, such as in antiviral defense or in the chromatin structure organization.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme dicer cuts dsRNA into smaller fragments called (1) siRNA, which form a complex with RISC and degrade specific (2) RNA.
