DNA polymerases are capable of editing and error correction, whereas the capacity for error correction in RNA polymerases appear

s to be quite limited. Approximately one error occurs in every 104 to 105 nucleotide incorporated in RNA. Given that a single base error in either replication or transcription can lead to an error in the protein coded by the gene or mRNA. Please suggest a possible explanation for this striking difference.

Explanation:

DNA polymerase replicates the DNA supplied to all new cells produced while RNA polymerase drives DNA copy RNA synthesis. Unless corrected, error in DNA replication could result in the transmission of the error DNA to all next-generation cells.

Protein synthesis error will cause faulty copies of RNA and degraded proteins. To order to ensure the transfer of key genetic information to future generations of cells, failure to DNA replication must be corrected.

Suppose a one-year old child is playing with a toy near an electrical out-let. He sticks part of the toy into the outlet. He get
Papessa [141]

Answer:

UCS: sticks part of the toy into the electrical outlet

UCR: frightened and crying

CS: toy

CR: frightened to toy

Explanation:

Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.

<u>Unconditioned stimulus</u> (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.

<u>Unconditioned response</u> (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.

<u>Conditioned stimulus</u> (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.

<u>Conditioned response</u> (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.

Dana is intending to breastfeed her baby after he is born. she has read that human breast milk differs significantly from cow's
ycow [4]
The hormones send signal to the mammary glands in the body for it to start to produce milk to feed the baby. However there are times humans rely on to cow's milk. There are differences though between the two.Human milk has more whey protein compared to the cow yet they has less casein which is another type of protein compared to cow's milk. For carbohydrates, human milk is higher than the cow's milk. For the fatty acid, the cow's milk contains more unsaturated fat.

You begin as one cell. Compare the DNA in your brain cell to the DNA of your heart cells. Explain. PLZZ HELP
andrew11 [14]
Certain genes that allow for a certain thing to happen are turned on or turned off as needed. A brain cell may have the gene needed to send electrical pulses to other brain cells or other parts of the body, whereas a heart cell may have the genes that allow it to contract to pump blood. (I don't know if those are real genes, but hopefully you get the idea)
