Answer:

Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.

Examples

AO (genotype) = A (phenotype)

BO (genotype) = B (phenotype)

Answer: I am a Shrub

Explanation:

A Shrub also called a bush is medium-sized woody plant with many stems which is shorter than a tree but taller than a herb having a range in height of about 6-10 metres Shrubs are divided into two --- Deciduous and evergreen.

Many Shrubs are planted in homes and gardens because of the aesthetic value they provide, including serving as wind breaks when many of them are planted together.Example of Shrubs include Rose, jasmine,Hibiscus tulsi, etc.

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu

uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
Forward and reverse primers (to customize the start of the enzyme reaction)
DNA polymerase (Enzyme required for replication of desired DNA region.)
DNA Template (the DNA to be copied)
PCR-grade water
Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
