Answer:
The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".
Explanation:
Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.
Golgi bodies/ golgi apparatus/ golgi complex are the diff. names
Answer:
E. Photosynthesis is an anabolic reaction, and cellular respiration is a catabolic reaction.
Explanation:
Anabolic or endergonic reaction is a type of reaction that uses energy. In this type of reaction small, simple molecules join to make larger complex molecules. For example photosynthesis, during which carbon dioxide and water are react to synthesise glucose and oxygen.
Catabolic or exergonic reaction is a type of reaction that gives energy. in this reaction large molecules are broken down into smaller ones. For example respiration, during which glucose in presence of oxygen is broken into carbon dioxide and water.
