Answer:
During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
Explanation:
The answer is : Light waves would be more likely to be refracted or diffracted, thus failing to reach plants and phytoplankton
Sunlight is needed by the producer(plants, phytoplankton) in the ocean to do photosynthesis. When an are is attacked by severe storm, the area will be covered by cloud of the storm which impede the light, cause it to be refracted or diffracted. This will cause less light comes to the producer of the plants and phytoplankton.
A. Sediments. Geologic refers to rocks and rock processes over time.
Answer:
B. positive
Explanation:
Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.
Answer:
(B) DNA polymerase I synthesizes DNA on lagging strands and DNA polymerase III synthesizes DNA on leading strands
Explanation:
Both the enzymes DNA polymerase I and DNA polymerase III involved in the process of DNA Replication with specialised functions. DNA polymerase I synthesize DNA on lagging strand where it degrades RNA primer and replace it with DNA. On the other hand, DNA polymerase III synthesize DNA from 5' to 3' end on the leading and lagging strand but stops at the RNA Primer.
