Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
Answer:
evolutionary theory of sexual behavior.
Explanation:
Answer:
I think this is the answer
Explanation:
Chloroplast. Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
Coral reefs have a symbiotic relationship with algae. Because of human activity, the ocean is absorbing high levels of carbon dioxide, which causes an increase in ocean temperature. <span>Due to these unfavorable conditions, corals expel algae, leading to bleaching. If corals go too long without algae, the corals will die. </span>
Answer:
Pollen
Explanation:
Flowering plants are plants classified as Angiosperms. They are the most diverse group of plants in the Kingdom Plantae. Angiosperms or flowering plants as their name implies are characterized by the possession of reproductive structures called FLOWER. The male reproductive flower called STAMEN produces their gamete in a structure called POLLEN while the female reproductive flower called PISTIL contains an ovary that produces egg cells called OVULES.
In flowering plants, the pollen of a male flower is transported to the receptive part of the female flower called STIGMA in a process called POLLINATION. The pollen contains the gamete (sperm cell) that conveys the genetic material (DNA) of the male plant. A fertilized ovule develops into a seed, hence, the reason flowering plants are called SEED-BEARING.
Therefore, pollen is the structure containing the genetic material (DNA) that is transported from one plant to another (same species) in flowering plants.
