DNA, or the instructions for making proteins, is found within the nucleus of the cell; while protein synthesis machinery is found in the cytoplasm of the cell. <span>The nucleus is the site of transcription, production of messenger RNA (mRNA) and after being post-transcriptional modified mRNA is exported from the nucleus. Translation of mRNA occurs within the cytoplasm (proteins are synthesized).</span>
Answer:
Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.
<span>The hydrologic, rock, and tectonic cycles are all interconnected. In the rock cycle, water moves regolith during erosion, and the tectonic cycle resurfaces rock through uplifting.The hydrologic, rock, and tectonic cycles are powered by the sun and by the Earth’s interior, the core.</span>
Answer:
The red one.
Explanation:
The red colour strands are the products of replication in which new DNA molecules are formed. The main purpose of replication is to produce extra set of DNA molecules for the new cell so that each cell receives extra molecules of DNA. Due to DNA replication, the cell has two types of DNA i.e. parent strands and new strands. The parent strands are blue in colour whereas the new strands are red in colour.
