Answer:
The correct answer is option E. "nucleotides can only be added to an available 3'-OH group on the transcript terminus".
Explanation:
RNA synthesis is catalyzed by an enzyme called RNA polymerase. RNA polymerase always catalyze the synthesis of new RNA from 5' to 3' because nucleotides can only be added to an available 3'-OH group on the transcript terminus. This has been confirmed in labeling experiments with γ-32P substrates which establish the presence of a triphosphate moiety in transcripts with either pppG or pppA.
Answer:correcting yourself
Explanation: they key to that question is “self correction” it’s when you find your mistake and correct it
Answer:
The correct answer is - contains many genes for transcription factors that are present in cnidarians and bilaterian animals.
Explanation:
Placozoans are the simplest known metazoan organism known on earth and found in warm water and all over the globe. Placozoans are very small approximately 2 to 3 mm.
These are basal forms of marine free-living multicellular organisms. In the molecular studies, it is found that they have similar genes that are present in cnidarians and bilaterian animals for transcription factors.
Answer:
Explanation:
Lysosomes and peroxisomes. These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell components.
The seahorse is found in many different locations around North and South America. They are typically located in the shallow tropical waters that are quite warm. They will be found living along the coral, the sea grass, and the mangroves. In Europe they are known to reside in the Thames estuary. Many of the larger species are living in the Mediterranean Sea.
Many species of seahorses are very territorial. The males often have about 11 square feet of territory. The females have up to 1,100 square feet. What they live though will influence how much area they have. In many regions that habitat range has gotten smaller and smaller.
In captivity the seahorses will be limited to a large aquarium. This can be a huge change in home range habitat for them. That is why the stress levels are very high and the survival rate low. Young in a captive state are more likely to do well because they haven’t become accustomed to the wide territory.
As a result the seahorses living in a given area have become more aggressive. They have also suffered from higher stress levels and more forms of disease. The aggressive behavior is typically when males are looking for females that they can mate with. It is also common when they are fighting for territory or food and that extends to both genders.
