To choose the strand the promoter acts to aim the RNA polymerase.

<h3>What does RNA polymerase do?</h3>

RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.

Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.

Iteru [2.4K]

Answer:

<h2>As transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location,  post-transcriptional processing in eukaryotes. </h2>

Explanation:

The transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location and can be co-translation.

As, in eukaryotes, the transcription occurs in the nucleus and then this transcript have to move in the cytoplasm to translation, so before reaching in the cytoplasm, various modifications occur in this transcript known as post transcriptional modification or processing ( include 5' capping, 3' poly-adenylation and RNA splicing).

As, in prokaryotes, both transcription and translation occur at same place so there is no time for modification for transcript because translation starts as the transcription is still going on.

Sketch and label a food-web that includes at least 6 different items. Make
astra-53 [7]

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
