Question: In prokaryotes, genes can exist as operons that are transcribed into a polycistronic mRNA, containing multiple genes in a single transcript. In eukaryotes, transcripts exist only as monocistronic mRNA containing a single gene. What fundamental genetic difference is responsible for this distinction?
(A) mRNA is transported outside of the nucleus in eukaryotes.
(B) Prokaryotic mRNA has a five-prime GTP cap.
(C) Prokaryotes use a single start codon for multiple genes.
(D) In eukaryotes, each gene has its own transcription initiation site
Answer:
(D) In eukaryotes, each gene has its own transcription initiation site
Explanation:
Eukaryotic mRNAs are monocistronic in nature which means that one mRNA carries the single transcript to be encoded. Each monocistronic mRNA is encoded by a stretch of a gene that has a specific initiation site to start the process of transcription. On the other hand, prokaryotes have some mRNAs that carry the code for two or more different polypeptides. These mRNAs are called polycistronic. For a polycistronic mRNA, multiple transcripts are transcribed under the single transcription initiation site.
Answer: Fungus
Explanation:
Fungi are microorgnaims characterized by the cell walls which is made of the substances known as chitin.
Most of the fungi are harmless and some of them are edible. Other fungi are infectious and can cause many fungal infections in the skin, lungs and nails of the organism.
It also causes itching, scaling and cracking of skin. Thrush is the condition which is caused by fungus Candila albicans which can infect the vagina, mouth and urinary tract.
The stimulus modality is one in which the body response to the stimulus and respond in each way accordingly. Two different stimulus can be used at two different time to sense different operation
Explanation:
There are five different types of sensory modalities and they are the visual auditory gustatory olfactory and the receptors. They function to identify the taste, smell, heat, light and sound. When a specific function is done the following sensory receptors are activated and they respond to the stimulus.
The sensory receptors at the finger tip are stimulated when we touch a hot or a cold object this is one type of function. On the other hand the synapses which occurs at the brain are due to the modulus of the brain activities like vision and responding to the activities.
Answer:
AUG- methionine, ,UCU- serine, UCG- serine
Answer:
B
Explanation:
All endothermic reactions need added energy and the phase is going from liquid to gas.
