Labeled parts of a DNA molecule

Biology

IceJOKER [234]3 years ago

Answer:

A DNA molecule is a polymer, specifically being a type of polymer known as a polynucleotide. In other words, it is made up of many nucleotides. Each nucleotide is made up of three main parts: one or more phosphate (P) groups, a nitrogenous base (adenine, guanine, cytosine, or thymine), and a deoxyribose (pentose, 5-carbon) sugar. Adenine always binds/hydrogen bonds to thymine, and guanine always to cytosine. (According to Chargaff's rules, the amount of pyrimidines is always equal to that of purines.) Hope this helps! :)

Answer:

DNA is made up of six smaller Molecules--- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine, and guanine).

Can life subsist on anything else but water?
guapka [62]
In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.

A positively charged molecule. This molecule consists of three hydrogen atoms bonded to an oxygen atom. What name is given to th
Romashka [77]

Answer:

The correct answer is d. hydronium ion.

Explanation:

Hydronium ion is a positively charged molecule that has three hydrogen atom bonded with an oxygen atom. Hydronium ion is formed when the water molecule gains an extra H+ ion from somewhere.  

This H+ ion easily form bonds with one of the lone pairs present on the water molecules. H2O is also a polar molecule and has a partially positive charge due to which the extra H+ ions get attracted to the negative pole of water and make hydronium ion. Therefore the correct answer is d.

mel-nik [20]

Answer:

A. Prions do not contain genetic information, which is affected by ionizing radiation.

B. Denaturants may affect the tertiary structure of prions.

C. Prions are proteins.

Explanation:

Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.

Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
