1. Special enzymes open two strands of a DNA molecule. 2. Nucleotides floating in the nucleus bind to a DNA strand following the rules for basepairing.
3. ?
4. The two strands of separated DNA reattach and restore the double helix.
Which step is missing from this description of transcription?
A.
The DNA strand leves the nucleus and attaches to a ribosome in the cytoplasm.
B.
The RNA strand permanently bonds to the DNA strand in the nucleus.
The DNA strand dissolves as all the DNA in the nucleus is converted to RNA.
C.
D.
The RNA message that is made from DNA seperates from the DNA strand.

Which plant has a visible leaf modification that will it conserve water in extremely dry environments?

Name one similarity and one difference between the morphology of a brachiopod and a bivalve

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.
