People believed that zebras were white animals with black stripes, since some zebras have white underbellies. Embryological evidence, however, shows that the animal's background color is black and the white stripes and bellies are additions.
Answer:
A compound contains atoms of different elements chemically combined together in a fixed ratio. A mixture is a combination of two or more substances where there is no chemical combination or reaction. ... Mixtures contain different elements and compounds but the ratio is not fixed nor are they combined via chemical bonds.
Explanation:
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).
