<h2>Answer</h2>

The right option is (A).

<h2>Explanation</h2>

The RNA gets its information from DNA to synthesise the proteins. It is different from DNA also due to the difference in one nitrogen basis as uracil. The thymine, the nitrogen basis that is only present in DNA is replaced with uracil to form RNA coding. The uracil also contains the same features as thymine has in DNA strains. Uracil makes a double H-bond with the adenine but does not contain CH4 group which is present in thymine.

Importance of science in everyday life

Andrew [12]

Explanation:

Science is very important in every activities of our daily life. some of them are,

It is used for cooking as the cooking materials are made with various science ideas.
It is used for buying and selling purposes such as measuring amounts of quantities.
It is used for lightning our house and also run various type of electronic devices to make our life effective through electricity. 
We use science in medical sector as all the requirements in medical sector needs the knowledge and skill of science from medicine to surgery. 
when we make compost manure, there should be bacteria todecompose it.

In part A, you analyzed genes that contribute to two diseases. (cystic fibrosis and muscular dystrophy) How can scientists use t

N76 [4]

Answer:

By designing suitable gene therapies in order to restore target gene expression.

Explanation:

Cystic fibrosis and muscular dystrophy are inherited genetic disorders associated with serious health problems. Cystic fibrosis is caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, and it is a condition associated with abnormal production of sticky mucus that leads to problems in the lungs and the digestive systems. On the other hand, muscular dystrophy is produced by mutations in genes localized on the X chromosome such as, for example, the gene 'dystrophin'. Gene therapy is an experimental approach used to compensate abnormal gene function by introducing exogenous genetic material and thus restore their altered protein products. Consequently, personalized gene therapies can be useful to treat inherited disorders such as cystic fibrosis and muscular dystrophy.

Verizon [17]

Answer:

to have cell walls made of chitin
eukaryotic heterotrophs

Explanation:

Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.

The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.

Kingdoms include different phyla closely related.

The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.

All the members of the kingdom

Lack mobility, growing on the ground, organic matter, or other surfaces.
They all have a rigid cell wall composed of chitin.
They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.
Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.
Reproduction is by spores, which are resistant to adverse environmental conditions.
