With respect to microRNAs, which, if any, of the following statements, is true?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. MicroRNA is a generic term that covers all tiny RNAs, ones that are less than 35 nucleotides long when mature.

  2. MicroRNA genes often occur in gene clusters within introns of protein-coding genes and are usually transcribed by RNA polymerase II.

  3. MicroRNAs regulate target genes by binding to complementary sequences on one DNA strand of the target gene.

  4. MicroRNAs normally regulate the expression of just a single target gene.

#Unit 8. Inheritance Biology

Genes that control coat color in mammals represent some of the best early examples of genes with multiple alleles exhibiting different phenotypes. A classic example is the C gene in hamsters. Three of the known alleles of this gene are C, ck and ca. Each supplies a different amount of black pigment to the coat hair. The phenotypes of three different homozygous strains are as follows.
Based on the concepts of dominance, determine whether ck and ca were dominant or recessive alleles by crossing the true-breeding sepia hamsters to true-breeding black hamsters. From the resulting F1 progeny phenotype, what would be the ratio of F2 phenotype
