Answer:
anther
Explanation:
The anther is responsible for producing cells by meiosis
It could have the most direct effect on the amount of mitochondria in cells and also the system of the membrane.
<span>Additional facts:
A test cross between an organism whose genotype for a certain trait is unknown and an organism that is homozygous recessive for that trait so the unknown genotype can be determined from that of the offspring.
Answer:
You'd use it when you wish to see if the one that you think is a homozygous dominant is a purebred, because if you did get a recessive offspring then it proves that the animal is a heterozygous and not a purebred.</span>
Answer:
- multiple pathways
- ligands/signaling molecules
- inorganic phosphate
- inactive relay proteins
Explanation:
Receptor Tyrosine Kinase:
- Receptor tyrosine kinase (RTK) is the largest class of enzyme linked cell surface receptors.
- When a growth factor or a ligand binds to two neighboring RTK receptors, the two receptors bind together and form a dimer.
- This change in the conformation of the RTKs activates the associated tyrosine kinase enzymes.
- Tyrosine kinases break down ATP to ADP and phosphorylate the RTKs. Cross phosphorylation between the receptors helps activate multiple tyrosine kinases on the neighboring RTK.
- Once phosphorylated, the cytoplasmic ends of the RTKs are available for docking by relay proteins or signaling molecules with an SH-2 domain.
Answer:
Sister chromatids separate from each other during anaphase of mitosis and the anaphase II of meiosis II. During the anaphase stage of mitosis these chromatids separate and one chromatid goes into each daughter cell. During cell division they are separated from each other and each daughter cell receives one copy of the chromosome.
