Question

Различия ДНК и РНК??

Answer 1

Различия ДНК и РНК:


1) ДНК:Содержит сахар -- дезоксирибоза
    РНК: Содержит сахар -- рибоза

2) ДНК: 4 азотистых оснований -- Аденин (А), Тимин (Т), Гуанин (Г), Цитозин (Ц)
    РНК: 4 азотистых оснований -- Аденин (А), Урацил (У),Гуанин (Г), Цитозин (Ц).

3) ДНК имеет структуру в форме спирали, двухцепочная.
    РНК имеет одноцепочную молекулу.

4) ДНК: Совершает функцию хранения наследственной информации и передача ее из поколения в поколение.
    РНК:  Участвует в матричном биосинтезе белка на рибосоме,то есть реализация наследственной информации

5) ДНК находится в ядре,митохондриях и хлоропластах
    РНК находится в ядрышке,рибосомах,цитоплазмах,митохондриях и пластидах.

6) ДНК способна к самоудвоению
    РНК не способна к самоудвоению

Answer 2

Differences Between DNA and RNA

DNA (Deoxyribonucleic Acid): - DNA is a double-stranded molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. - It is the primary information-carrying molecule in the cell and is found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. - The structure of DNA is a double helix, consisting of two long chains of nucleotides twisted around each other.

RNA (Ribonucleic Acid): - RNA is a single-stranded molecule that is involved in various biological roles, including coding, decoding, regulation, and expression of genes. - It is usually found in the cytoplasm as well as within the nucleus of a cell. - RNA is typically involved in protein synthesis, but it also plays a role in the transmission of genetic information in some viruses.

Key Differences: 1. Structure: DNA is double-stranded, while RNA is single-stranded. 2. Location: DNA is primarily found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells, whereas RNA is found in both the nucleus and the cytoplasm of a cell. 3. Function: DNA carries genetic information, while RNA is involved in various biological roles, including protein synthesis and gene expression.

In summary, DNA and RNA differ in their structure, location, and biological functions, with DNA being double-stranded and primarily located in the nucleus, and RNA being single-stranded and found in both the nucleus and cytoplasm, with various biological roles including protein synthesis and gene expression.
