Answer: gravity and an environmental factor
Explanation:
The solar system formed dust and many gases in a nebula. The center of the nebula eventually became the sun. The flat rings of outside the nebula became the orbit paths, and that is where the planets stay and rotate around the sun. After that dust particles and gases that were found were all combined up to create planets and moons.
Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.
CHECKPOINT M in the cell cycle is affected by paclitaxel.
Paclitaxel (PTX) is a compound that is sold under the brand name "Taxol" which is used to treat cancer. G1, G2 and M are the 3 checkpoints where all the chromosomes get attached attached to the spindle fibers. Paclitaxel inhibits the assembly and disassembly of the microtubules and prevents the separation of chromosomes during cell division.
Answer:
nonsense codon; shift in reading frame; nonsynonymous codon.
Explanation:
The mutation that affects the single nucleotide of nucleic acid are called as point mutation. It includes substitution, insertion or deletion of single base pair.
- When a premature nonsense or stop codon is inserted in the DNA sequence nonsense mutation occurs such as UAU is replaced by UAA (stop codon).
- A single nucleotide is added or deleted (shift in reading frame) in frame shift mutation.
- The amino acid are changed because of change in codon (nonsynonymous codon) by missense mutation.
- The mutation does not change the codon thus does not change the amino acid (synonymous codon) and does not express it are called as silent mutation.
