Answer:

Primers should be:

3 'ACGTATGTCGCTTAGT 5'

5 'ACGTTCCAGTCAATGA 3'

Explanation:

DNA replication occurs with the need for the presence of primers that are a small sequence of nitrogenous bases that will allow the initiation of replication.

Primers are extremely important in PCR and are represented as small pieces of single-stranded DNA that specify the region of DNA that should be replicated during PCR. These primers attach to the single strand of DNA by pairing the nitrogenous bases allowing the DNA polymerase to recognize where replication begins.

Regarding the question above, the primers should be:

3 'ACGTATGTCGCTTAGT 5'

5 'ACGTTCCAGTCAATGA 3'

eimsori [14]

Answer:

Height is affected by multiple pairs of genes on different chromosomes.

Explanation:  

The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.

Photosynthetic pigments are found in all algae like chlrophyll a and yellow or orange carotenoids. Also, almost all algae is aquatic. Also, all algae are eukaryotes and the sex organs are unicellular in all algae.
