Answer:
A) A transgene integrated into a heterochromatic region of the genome.
Explanation:
This is most likely the reason why the transgene is not expressed in the fifth cell line. It is likely that the transgene was integrated into a heterochromatic region of the genome. Heterochromatin consists of genetically inactive satellite sequences, and many of these are repressed to various extents. Moreover, because this is a tightly packed form of DNA or condensed DNA, it is inaccesible to polymerases and thus not transcribed.
Answer:
d. 28,650 years
Explanation:
Since 14C has a single half-life of 5,730 years
The number of years that is going to make up 5 half-lives for 14C will be;
5,730 years × 5 = 28,650 years
Answer:
haploid daughter cells
Explanation:
Meiosis involves two divisions of the parent cell resulting in four daughter cells. Each daughter cell has half the number of chromosomes as the parent cell. In meiosis I, the number of chromosomes is reduced by half thus called reduction division. The product of meiosis I is two diploid daughter cells.
Answer:
It's responsible for cellular respiration in both plants and animal cells. The difference is that plants also have chloroplasts that perform photosynthesis. Animals get their energy by eating food, digesting it, and turning it into the base sugars, proteins, and lipids that the cells can burn to perform cellular respiration (which makes ATP).
