In snapdragons, there is one allele that produces red flowers and another allele that produces white flowers. Neither allele is

dominant and heterozygous individuals have pink flowers. A plant breeder decides to cross a red-flowered snapdragon with a pink-flowered snapdragon. What percentage of the offspring do you expect will have red-flowers? ( Enter the number only without the percent sign. For example, enter 100% as 100 and enter 12.5% as 12.5)

Answer:

50

Explanation:

A punnet square can be described as a diagram which illustrates all the possible outcomes of a cross. It is used to tell about the percentage chances for the kinds of genes being transferred to offsprings.

In order to check the percentage of red flowers we can draw a punnet square. As red flower is a recessive trait and pink flower a heterozygous trait,the punnet square shows that a cross between them will give 50 percent red flowers and 50 percent pink flowers.

irina [24]

Answer:

Binding of glucose to hexokinase causes a conformational change in the enzyme. This is an example of the<u> induce-fit </u>model of enzyme catalysis.

Explanation:

The induce- fit model is generally the most accepted theory for enzyme catalysis. This theory states that the active site of an enzyme is not always a perfect fit for a substrate. The substrate induces changes in the active site so that it can fit into the active site. This theory is contrary to the theory of lock and key model, which stated that substrates exist as a perfect match for particular active sites of an enzyme.

Select the correct answer from each drop-down menu.
chubhunter [2.5K]

Answer:

It contains Uracil (U) instead of Thymine (T).

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Explanation:

Primers:

Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.

Primer removal:

After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Best Answer:

Because It contains Uracil (U) instead of Thymine (T).
