1. DNA is composed of the bases adenine (A), cytosine (C), guanine (G), and thymine (T). RNA is composed of adenine, cytosine, guanine, and uracil (U). Look at the SIMULATION pane. Is the displayed segment a part of a DNA or RNA molecule? How do you know?

Answer:

The molecule is of DNA I know this because I see that adenine is paired up with thymine in RNA uracil replaces thymine

The segment is likely part of a DNA molecule, as it contains adenine, cytosine, guanine, and thymine. The absence of uracil and the double-helical structure confirm its DNA nature.

The displayed segment in the simulation pane appears to be a part of a DNA molecule. This determination is based on the presence of the bases adenine (A), cytosine (C), guanine (G), and thymine (T). In DNA, adenine pairs with thymine, and cytosine pairs with guanine through hydrogen bonds, forming the characteristic double helical structure. The presence of thymine is a key indicator of DNA, as uracil replaces thymine in RNA.

The absence of uracil (U) in the displayed segment further supports the conclusion that it is DNA. In RNA, uracil pairs with adenine, while the absence of thymine distinguishes RNA from DNA. Additionally, the structure of the displayed segment is indicative of DNA's double-stranded helical configuration.

In summary, the presence of thymine and the absence of uracil, along with the characteristic double-helical structure, strongly suggest that the displayed segment is part of a DNA molecule.
