Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.
Answer:
They are composed of molecules that contain carbon-carbon bonds.
They undergo chemical reactions to use energy they acquire from the environment.
Living things are organisms that displays characteristics of life. These characteristics includes the ability to grow, reproduce, use of energy, excrete out waste, respond to the environment and have organised structure.
The biggest terrestrial mammals on Earth are African elephants. Their wider ears, which resemble the continent of Africa somewhat, help to distinguish them from their Asian kin. (Elephants in Asia have more compact, rounder ears.)
<h3>What are the large species of elephant?</h3>
Scientists have discovered that there are actually two species of African elephants, despite the fact that they were previously considered to be a single species. Both of these species are endangered.
While forest elephants are smaller creatures that dwell in the woods of Central and West Africa, savanna elephants are larger creatures that wander the plains of sub-Saharan Africa. Savanna elephants are classified as endangered by the International Union for the Conservation of Nature, whereas forest elephants are classified as severely endangered.
