The looping of DNA around histone proteins... a. Produces the characteristic helix shape of the DNA b. Allow the room for cellular machinery to reach all genes so they may be transcribed c. Compacts the DNA allowing a large amount of DNA to fit into the cell d. PreventS the DNA from becoming kinked and breaking e.
Answer:
- Complete dominance: one allele masks the expression of the other gene variant or the phenotype is caused by the absence of gene function when both alleles are recessive.
- Incomplete dominance (codominance): both alleles are expressed and contribute to the phenotype
Explanation:
Complete dominance is a type of dominance by which one allele (dominant allele) completely masks the effects of another allele (recessive allele) in heterozygous individuals (i.e., individuals carrying two different gene variants or alleles). On the other hand, codominance refers to a type of incomplete dominance where both alleles in the genotype are observed in the phenotype. Complete dominance is caused when the recessive allele is not expressed, while if both alleles are expressed it is called incomplete dominance.
<span>A. free radical
</span>A substance continually produced in our cells that, over time, may cause damage to DNA and other important cell structures is known as a free radical.
NOT:
B. functional food
<span>C. direct additive </span>
<span>D. indirect additive</span>
The name of a structure that performs a specialized function within a cell is an organelle. These help do various things to keep the cell as healthy as possible and keep it running as quickly and efficiently as possible.
I believe the answer is 20, sorry if it’s wrong :(
