The answer would be D.: <span>Helicases separate the two strands of the double helix, and DNA polymerases use each of the original strands as templates to create two new strands. :)</span>
Answer:
A zinc finger is also known as zinc-binding repeats or ZnF that are molecular scaffold which is characterized by the coordination of Zn²⁺ ions so it can stabilize the fold.
The zinc fingers consist of several amino acid sequence 2 histidine and 2 cysteine residues at intervals. These residues bind to the zinc atom covalently and form finger-like motifs.
They are a major family of eukaryotic transcription factors. These are identified in a significant regulatory state such as developmental control genes and proto-oncogene by binding to the DNA, RNA, or protein.
Answer:
An Endoplasmic reticulum
Explanation:
A living organism can either have prokaryotic or eukaryotic cells.
Eukaryotic cells have a defined nucleus and other membrane bound organelles whereas prokaryotic cells lack membrane bound organelles such as mitochondrion and chloroplast.
Endoplasmic reticulum are membranous system that forms a system of flattened sacs in the cytoplasm.
These organelles can only be found in eukaryotic cells and not prokaryotic cell.
A primary role for the glucose molecule is to act as a source of energy; a fuel. Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy.
