The period gene of Drosophila melanogaster encodes for a stretch of Thr-Gly repeated in tandem. In natural populations, the three most common alleles encode for 17, 20 and 23 Thr-Gly repeats. The amplification by PCR of the allele encoding for 20 Thr-Gly repeats produces a fragment of 320 bp. Using the same set of primers, what is the size expected when amplifying the 17 Thr-Gly allele?
317

In a certain species of plant loci A, B and C have an additive effect on the colour of the flower. Alleles A, B, and C are dominant and alleles a, b and c are recessive. Knowing that a plant with genotype AAbbCc has a pink flower, which genotype, among the ones listed below, will produce the same phenotype?
Aabbcc.

AaBbCc.

In pea plants, tall (T) is dominant to dwarf (t) and yellow (Y) is dominant to green (y). In a cross of true-breeding tall yellow peas x dwarf green…
Next-generation sequencing reveals that six new mutations have occurred in the coding regions of genes in an individual diploid fly. If the coding regions of this fly comprise 100 million nucleotides per haploid genome, what is the mutation rate per nucleotide?
The Dscam locus in Drosophila melanogaster has 24 exons. Four of these exons are able to undergo alternative splicing. Exon 4 has 12 possible splice variants, exon 6 has 48 variants, exon 9 has 33 variants, and exon 17 has 2 variants. If all splicing combinations are possible, how many different Dscam protein sequences could be encoded by a single allele at this locus?

- What are paralogous and orthologous genes?

- What is the first step in quantifying the relative amounts of mRNA in different tissues? Would this method be useful in determining which immune system genes might be over-expressed in severe Covid cases? Why or why not? Could quantitative PCR, which uses a DNA-binding dye, to show how many copies of the target DNA sequence could be used to quantify the amount of mRNA in a cell? Would you expect that a metabolically active tissue such as the liver would show more cDNA copies in such a method, compared to less metabolically active tissues such as skin cells? One reason that the types and amounts of mRNAs are quantified in different tissue types is to compare which genes are activated and which are inactive. It used to be thought that any gene that was transcribed was automatically translated. The discovery of RNA-degrading systems shows that the real situation in cells is more complemented.
