Explanation:
The degree to which chromatin is compacted greatly affects its accessibility for transcription, and thus, gene expression.
<h3>What is Transcription?</h3>
This is the process which involves copying a segment of DNA into RNA in organisms.
When chromatin is condensed, DNA becomes less accessible for transcription factors and vice versa which was why it was chosen as the most appropriate choice.

Answer:
Most birth defects can't be prevented, but you can take some steps to reduce the likelihood of environmental effects. Remember to always discuss your concerns with your healthcare provider and follow their instructions regarding screening tests, medications, etc.
Explanation:
Answer:
1: Light-dependent reactions:
Reactants: H2O, ADP, NADP
Products: O2, ATP, NADPH
Location: Thylakoid membranes of chloroplasts in cells of leaves
2: Light-independent reactions
Reactants: CO2, H2O, ATP, NADPH
Products: C6H12O6 (glucose), ADP, NADP
Location: Stroma of chloroplasts in leaf cells
Explanation:
Photosynthesis takes place in two stages:
1: Light-dependent reactions: This stage includes splitting of water in the presence of sunlight and release of electrons and oxygen gas. The electrons are channeled into the electron transport chain and result in the formation of ATP and NADPH. This stage includes photosystem I and II present in the thylakoid membrane. Hence, light-dependent reactions of photosynthesis occur in the thylakoid membrane of chloroplasts and form ATP and NADPH.
2: Light-independent reactions: Also called as Calvin cycle, the light-independent reactions use ATP and NADPH formed during light reactions of photosynthesis to fix CO2 into glucose. The enzymes of the Calvin cycle are present in the stroma of chloroplasts and hence, this stage of photosynthesis occurs in the chloroplast stroma.
