Answer: The frequency of the b allele is calculated as follows: since there are 2 alleles in each organism, total number of genes is 200. The number of white alleles is 10*2+30 (since there are 2 copies of the alleles in white organisms and 1 copy of the b allele in the white wings with blue blotches). So the total number of white alleles is 20+30=50 white alleles. The frequency of the white allele is then 0.25. So the frequency of the blue allele is 1-0.25=0.75. Since heterozygous term is 2*p*q, the frequency of the Bb genotype is 2*0.25*0.75=0.375. Hope that helped!
Traditionally, some textbooks from the United States used a system of six kingdoms<span> (Animalia, Plantae, Fungi, Protista, Archaea/Archaeabacteria, and Bacteria/Eubacteria) while textbooks in Great Britain, India, Australia, Latin America and other countries used </span><span>five kingdoms</span>
Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
True.
Parenchyma cells are the most abundant type of cells in a plant since they make up parenchyma tissue which is the most common tissue in plants.
Parenchyma cells have thin walls, and posses large vacuoles as well as distinct intercellular spaces.
Parenchyma cells have many functions. Each function is largely determined by where the cell located.
Those found in roots and stems are used to store food in form of starch, and water. The large vacuoles in the cells is where the food and water are stored.
