Study Notes
Plant Anatomy
- Plant anatomy examines the structure of plant tissues and cells.
- Cells combine to form tissues that share similar characteristics and functions.
- The area within the plasma membrane is referred to as the cytoplasm.
- Primary cell walls (C.W) are primarily made of cellulose, a polysaccharide polymer of glucose.
- Plant cell growth involves the processes of initiation, expansion, and specialization.
DNA Replication
- DNA replication includes four main stages: initiation, elongation, termination, and stabilization.
- Replication initiates at specific sites on chromosomes known as origins of replication (Ori C).
- This process is semi-conservative, meaning each new DNA molecule consists of one old strand and one new strand.
- DNA replication proceeds in one direction, ensuring accuracy and efficiency.
- Single-strand binding proteins (SSBs) stabilize exposed single-stranded DNA, preventing breakage and rejoining.
- The gyrase enzyme plays a key role by relaxing supercoiled DNA, allowing accessibility for replication machinery.
