Answer:
Codominance
Explanation:
<em>Codominance is a genetic situation in which the two alleles representing a particular gene exert equal effects on each other when in heterozygous condition. Both alleles are phenotypically expressed in the heterozygous organism.</em>
In this case, the black and brown coat color were expressed in the resulting offspring of the cross, a clear indication of codominance.
Answer:
When the first replication takes place, 50% of the DNA will be radioactive, that is, one strand of each sister chromosome. After another round of replication, the percentage of radioactive DNA goes down to 25%.
Explanation:
Every time replication occurs, half the DNA is used as template and the other half is newly synthesized. After two rounds of replication, there will be 4 chromosomes.
Hope that answers the question, have a great day!
Answer:
C. The base
Explanation:
The nitrogenous bases, Adenine, Guanine, Thymine and Cytosine in DNA are the variable elements in the nucleotides. Nucleotides are constituted by three elements: The sugar (deoxyribose) and the phosphate group constitutes the backbone of the double helix and are constant in all nucleotides. Also, all nucleotides have carbon and nitrogen atoms.
B) mitochondria
