Identify the plasmid that must contain the CD3γ core promoter sequence but the fewest or no negative regulatory sequences. Based

on the data in Figure 2, describe the most likely cause of the variation in luciferase activity among the cells that contain plasmids pCD3γ-419 , pCD3γ-309 , pCD3γ-239 , and pCD3γ-199 . Calculate the approximate percent increase in luciferase activity between cells containing plasmid pCD3γ-59 and cells containing plasmid pCD3γ-149 . Round to the nearest whole number.

Answer:

Check the explanation

Explanation:

The luciferase mRNA is translated to its corresponding protein in the ribosome which is present in the cytoplasm of the cell.

In the cytoplasm, the chain of ribosome sits on the mRNA and forms a structure called a polysome. This helps in the fast synthesis of protein.

The three-nucleotide genetic code in the mRNA which is being read by the ribosome dictates the correct arrangement of amino acids through particular tRNA.

how does the random alignment of homologous chromosomes contribute to genetic variation in a population
SCORPION-xisa [38]

The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.

During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.

The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.

Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.

During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.

In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.
