The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
They are a fungi that harvest energy from what they are attached to and can collect the water from the water fall
Answer:
a unit of heredity that causes formation a phenotypic characteristics
Answer:
C. tumor suppressor
Explanation:
Tumor suppressor genes encode for proteins which inhibit cell proliferation in some way. One copy of this gene is sufficient to control cell proliferation so both the alleles must be mutated to promote tumor development. Mutation may be a deletion or point mutation.
Tumor suppressor genes are known to code for five classes of proteins:
- Intracellular proteins which inhibit cell proliferation through specific stage of cell cycle
- Receptors for hormones that inhibit cell proliferation
- Apoptosis promoting proteins
- Enzymes involved in DNA repair
- Check point control proteins that arrest cell cycle on detecting any abnormality
Answer:
Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.
Explanation:
If you are referring to the picture attached and the choices given:
- Hydrogen atoms in water molecules are only attracted to other hydrogen atoms.
- Oxygen atoms in water molecules are attracted to both oxygen atoms and hydrogen atoms.
- Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.
- Hydrogen atoms in water molecules are only attracted to an oxygen atom in the same water molecules.
What you can see there is what we call hydrogen bonding. The oxygen atoms are attracting the hydrogen of other water molecules. This type of bond forms in liquid water. Oxygen atoms of a water molecule are kind of negatively charged and can attract the partially positively charged hydrogen atoms of other water molecules.
