Answer:

The answer is when the cell express different genes.

Explanation:

Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.

What does it mean when scientists say that living organisms share a universal genetic code?
lesya [120]
When scientists say they share a universal genetic code it means that all organisms it can mean either DNA as the main source of hereditary information in all life forms we know of  or more likely that all organisms we know of use a three base pair code for the synthesis of proteins, DNA produces mRNA. This mRNA is read three base pairs at a time by a ribosome and this is called the genetic code.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enz
Andre45 [30]

The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.

Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second.  It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.

What type of allele will be expressed if both dominant and recessive alleles are present for a given trait?.
posledela

Answer:

The dominant allele will be expressed.

Explanation:

When both alleles are present in the genotype, the dominant allele "masks" the recessive allele so that only the dominant trait is expressed.
