Answer:
DNA--> RNA --> Protein
Explanation:
The central dogma of molecular biology describes the flow of genetic information in cells from DNA to messenger RNA (mRNA) to protein. It states that genes specify the sequence of mRNA molecules, which in turn specify the sequence of proteins.
Answer: true
Explanation: is on quizlet :)
Answer:
Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by endoplasmic reticulum _______ and the sugars are added in ___ ER/Golgi__ apparatus.
Explanation:
The protein part of all glycoproteins are synthesized from polyribosomes that then bind to the endoplasmic reticulum (ER). Then the processing of the sugar groups occurs co-and post-translational in the light thereof continuing in the Golgi apparatus for the N-linked glycoproteins.
There are some proteins that are glycosylated inside the ER and then pass to the Golgi (N glycosylation) and others in the Golgi directly (in case of O-glycosylation)
Environmental Impacts
With a hierarchy of prey and predators that control population growth, ecosystems are carefully balanced. Species that become extinct are removed from the food chain. Animals that consumed the recently extinct species must discover alternative food sources or risk going hungry.
The populations of other plants or animals may suffer as a result. Additionally, if a predator goes extinct, the population of its prey may increase, tipping the balance of nearby ecosystems.
Effects on People
Humans and endangered creatures must coexist in the same ecosystem. That implies that human existence will change if a species' population is declining. For instance, when the American bison population started to decline, people who depended on its meat or fur for warmth or trade suffered and had to turn to alternative sources of nutrition and revenue.
Economic Repercussions
The endangered honey bee is an illustration of how the economy is dependent on specific species. Bee numbers have decreased significantly in recent years, by more than 60% in the United States since 1947.
Bees pollinate a wide variety of plant species, including those that make up a large portion of the average person's diet. The U.S. Department of Agriculture values bee pollination highly, valuing it at billions of dollars annually to the economy.
