Pollen grains land on the stigma and move down the pollen tube into the ovary.
It is translation. Transcription is from DNA to RNA and Translation is from RNA to proteins
Answer:
Mitotic phase
Explanation:
Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:
- G1 (gap 1 phase)-the cell grows and becomes larger
- S phase- replication of DNA, duplication of centrosomes
- G2 (gap 2 phase)-proteins and oranelles are made
Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:
- prophase-condensation of chromatin into chromosomes, the nuclear envelope breaks down, mitotic spindle formation
- metaphase-the chromosmes line up (metaphase plate)
- anaphase-the siste chromatides move toward opposite cell poles
- telophase-the nuclear envelope forms again, cell division is almost complete
Answer:
24 chromosomes
Explanation:
The Human Genome Is Composed of 24 Different Types of DNA Molecules. Human DNA is packaged into physically separate units called chromosomes.
