What are stem cells and how are they being used?

Answers

Answer:

Stem cells are special human cells that are used to repair damaged tissues

Answer:

In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and divide indefinitely to produce more of the same stem cell. Stem cells are undifferentiated cells that can turn into specific cells, as the body needs them. Scientists and doctors are interested in stem cells as they help to explain how some functions of the body work, and how they sometimes go wrong.

How many times does the rrTt combination appear in this Punnett square?

Answers

Answer: The combination produced is RRtt.

The combination rrTt does not appear in this punnett square.

Explanation:

As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.

A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment. It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.

Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.

The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.

To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.

Which is the role of restriction enzyme.

Answers

The role of a restriction enzyme is essentially used to cut a single gene from a larger piece of DNA. It has a very important role to play in experiments investigating cloning, and in the construction of particular DNA molecules.

Answer:

Pepsin, a common enzyme found in the stomach, is most active at pH values between 0.5 and 2.5. It works slowly between pH values of 2.6 and 3.4. Beyond a pH of about 3.5, it becomes completely inactive. Why does this happen? A) The enzyme inactivates because it melts into a liquid when it is not at the right pH. B) The protein chain in the enzyme is denatured, permanently inactivating it as the pH approaches 7. C) The enzymes slow down, because changing the pH changes the temperature as well, and affects the reaction.
