1) RNA polymerase finds the promoter sequence on DNA.
2)RNA polymerase reads the DNA and builds complementary sequence.
3) Intron séquences are spliced out and exons are joined together.
4) The ends of the mature transcript are protected before it leaves the nucleus.
5) The mRNA attachés to the ribosome.
6) transfer RNA arrives at the ribosome and the anticodon complements to the mRNA codon.
7)amino acids form peptide bonds as tRNA molecules match the mRNA.
Label O is organic material, label A is topsoil, label B is subsoil and label C is weathered rock. They represent different soil layers.
<h3>Soil layers</h3>
Soli layers, also called horizons, refer to the different layers observed on the ground.
The topsoil is a layer of soil composed of a mixture of sand, silt, clay and organic material referred to as humus.
Weathering rocks refer to the dissolved rocks and/or minerals on the Earth's surface.
Subsoil refers to the layer under the topsoil on the surface of the ground.

Answer:To be considered a source of water pollution, the source must include a chemical.
Explanation:
Answer:
This question lacks options, options are: a.related. b. homologous. c protein-coding, d. comparative. The correct answer is b.
Explanation:
Homology refers to the fact in which the sequences of two or more proteins or nucleic acids are very similar due to the fact that they have the same evolutionary origin. Normally two sequences have a high similarity because they are homologous, that is, they share a common ancestor.
If two sequences in an alignment are from a common ancestor, mismatches can be interpreted as point mutations (substitutions), and gaps as insertion or deletion mutations introduced into one or both lineages in the time since they diverged.
