Concept explainers
A.
To find: Whether the given statement “Each eukaryotic chromosome must contain the following DNA sequence elements; multiple origins of replication, two telomeres, and one centromere” is correct or not.
Concept introduction: In a eukaryotic chromosome, roughly about 3.2 billion
B.
To find: Whether the given statement “Nucleosome core particles are 30 nm in diameter” is correct or not.
Concept introduction: In a eukaryotic chromosome, roughly about 3.2 billion nucleotides are spread over 23 different chromosomes. Each chromosome consists of enormously long linear DNA molecules associated with proteins that fold and pack the fine thread of DNA into a more compact structure. There are many important regions in a chromosome that are concerned with several vital functions. During the time of cell division, eukaryotic chromosomes condense into highly coiled four-armed structures. The high degree of coiling and systematic organization of genetic content in its arms reveals the high efficiency of eukaryotic chromosome.

- Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.arrow_forwardH gene assorts independently from the I gene. Both on autosomes. One man and one woman, both of HhIAIB genotype. Determine the blood type of progeny and fractions out of 16arrow_forwardAlleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…arrow_forward
