Final answer:
RNA can be considered a disposable copy of a DNA segment, as mRNA is transcribed from DNA and used for protein synthesis before being degraded. Uracil (U) is found in RNA instead of thymine (T), and RNA is typically single-stranded, not forming a double helix like DNA. The statement is True.
Step-by-step explanation:
During the process of transcription, a segment of DNA is copied into RNA, specifically messenger RNA (mRNA). This mRNA then serves as a template for protein synthesis in a process called translation, making it akin to a disposable photocopy of DNA that is used for a particular function and then degraded. True or False, A, C, G, and T represent the bases in RNA? This statement is false because RNA contains the bases adenine (A), cytosine (C), guanine (G), and uracil (U), with uracil replacing thymine (T) found in DNA. True or False, the two polynucleotide chains of RNA twist into a double helix shape? This statement is generally false because RNA is typically single-stranded and does not form a double helix like DNA, although it can form complex three-dimensional structures through internal base pairing.
