1. Compare and contrast the functions of DNA and RNA.
xz_007 [3.2K]

Answer:

  • compare and contrast
  • DNA replication works
  • process of transcription

Explanation:

COMPARE AND CONTRAST:

DNA is a double-stranded molecule while RNA is a single-stranded molecule. DNA is stable under alkaline conditions while RNA is not stable. ...DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine

HOW IT WORKS:

How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

PROCESS OF TRANSCRIPTION:

Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase is the maintranscription enzyme. Transcriptionbegins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).
