Which of the following best describes how a liver cell and skin cell have the exact same DNA

Though not exact, the statement that best describes how a liver cell and skin cell have the exact same DNA sequence and yet look different and perform different functions is the last one, the DNA is expressed differently, which leads to proteins being "expressed" differently in each cell.

During early embryonic development, the few cells that make up our organism are totipotent in nature. A totipotent cell is one with the capability to produce any tissue in the human body. All the cells that later make up our bodies are derived from these.

This explains that although not all of the DNA sequence is expressed at all times, the DNA is still present in the cell, meaning that option 1 is false. Option 2 is also false due to the fact that although mutations can occur from time to time, they are certainly not a common process nor are they normal. Finally, option 3 is false given that tRNA's only role is to apport the correct amino acid for each sequence.

As development continues, cells specialize into specific tissues. They do this by compressing certain areas of their DNA, making it unreadable and therefore limiting the expression of that area of the genetic code. This causes the proteins that are synthesized to be unique for each type of tissue.

Which way does earth rotate—from east to west, or west to east? Explain your answer.

Offspring grow up to exhibit many of the same characteristics as their parents because of the _______ they receive from their pa

faust18 [17]

Answer:

Genes

Explanation:

A gene is a hereditary unit that parents pass to their offspring, and they will determine the kind of characteristics the baby will have like will they be short or tall, have blue or brown eyes, will they have blond or black hair. The offspring will get different genes from its parents and it will therefore be genetically unique. Some traits or characteristics may be dominant over others. For example the mother has brown eyes and the father has blue eyes, so in this case eye color has two alleles (an allele is a specific version of a gene, in this case allele for blue eye color and an allele for brown eye color), and now the baby is born with brown eyes, so brown eye color was dominant over the blue eye color so that is the trait that we will see in the baby. The genetic is a lot more complex but this is a more simplified explanation of how offspring express certain traits from their parents.
