Answer: James Watson, Francis Crick, and Rosalind Franklin (these are just 3)
Explanation:
In 1952, Watson and Crick took the first X-ray picture of DNA. Created by Rosalind Franklin, she used a technique called X-ray Crystallography, that is how they discovered the helical structure of DNA
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits. DNA replication is an essential process and the basic mechanism is conserved in all organisms.

Bacteria without plasmid will only grow in the media without penicillin since it doesn't have immunity.
Bacteria with recombinant plasmid with VGP gene, n<span>on-recombiant plasmid, Recombinant plasmid but no vgp gene can grow in both media(with or without penicillin) because they can withstand penicillin.</span>
The maximum heart rate is calculated by removing the given age from 220. In this case, we are given 15 as the value for age. So, we have: 220 15 = 205.
To calculate the heart rate range, we have to calculate for three zones:
Zone 1= Maximum heart range * 0.6 = 205 * 0.6 = 123.
Zone 2 = Maximum heart range * 0.7 = 205 * 0.7 = 143.5.
Zone 3 = Maximum heart range * 0.8 = 205 * 0.8 = 164.
Therefore, the heart rate range = 123 - 164.
Thus, the correct option is B.
scientists MUST test the hypothesis several times and if they keep getting the same results, it is now considered a theory.
