Explanation:
Watson & Crick discovered that DNA is composed of two (2) strands of DNA running antiparallel to each other. One strand is oriented in the 5’ -> 3’ direction while the other is oriented in the 3’ -> 5’ direction. The nitrogenous bases of the strands are found in between the two-strand backbones and they form hydrogen bonding with each other. Specifically, pyrimidines (Cytosine and Thymine) pair with purine (Adenine and Guanine).
The space between the strands is even throughout like a ladder with rungs of equal lengths. However during the twisting on the DNA helix, there are major grooves and minor grooves that form along the helix because of the nature of how the nitrogenous bases are attached to their respective strand. They do not project from their strands at 90 degrees.

Answer:
Bet
Explanation:
1. The radiaton from the X-ray waves can be harmful
2. Lack of resources comes on part of both the provider as well as the patient as the provider may not necessarily have the appropriate equipment or updated technology yet to detect such conditions such as in smaller town hospitals or even the patient may not have the financial or transportation resources in order to obtain these. Another one but while being a little subjective I think could even be a lack of knowledge on both of our parts as well as healthcare providers don't always have all the answers to everything let alone the resources as mentioned earlier or even perhaps the patient doesn't know the earlier signs and symptoms of certain cancers and even more so some cancers are VERY difficult to detect, especially until its too late.
3. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white
4. An X-Ray will be neccesary, ultrasounds exam organs while x-rays examine bones
