What is Deoxypentose nucleic acid?
: any of various nucleic acids yielding a deoxypentose on hydrolysis especially : deoxyribonucleic acid.
What is the molecular structure of nucleic acids?
Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
What is the monomer of nucleic acids?
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
What did the Watson and Crick paper say about the biology of DNA?
Watson and Crick realized at the time that their work had important scientific implications beyond a “pretty structure.” In this statement, the authors are saying that the base pairing in DNA (adenine links to thymine and guanine to cytosine) provides the mechanism by which genetic information carried in the double …
What is the biggest chemical difference between RNA and DNA?
One of the major structural differences between DNA and RNA is the sugar, with the 2-deoxyribose in DNA being replaced by ribose in RNA.
What are the four kinds of bases found in DNA?
Adenine, thymine, cytosine and guanine are the four nucleotides found in DNA.
What are the 4 bases in RNA?
RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.
What are the 3 key roles of DNA?
What are the three key roles of DNA? Storing, copying, and transmitting information.
What are the pairs in DNA?
DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
What is the structural difference between DNA and RNA?
So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
How many base pairs are in DNA?
3 billion base pairs
Why does a only pair with T?
The only pairs that can create hydrogen bonds in that space are adenine with thymine and cytosine with guanine. A and T form two hydrogen bonds while C and G form three. It’s these hydrogen bonds that join the two strands and stabilize the molecule, which allows it to form the ladder-like double helix.
What does T pair with in RNA?
The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn’t contain thymine bases, replacing them with uracil bases (U), which pair to adenine1.
Why can’t AC and GT pairs form?
The arrangements of atoms in the four kinds of nitrogenous bases is such that two hydrogen bonds are formed automatically when A and T are present on opposite DNA strands, and three are formed when G and C come together this way. A-C or G-T pairs would not be able to form similar sets of hydro- gen bonds.
Is DNA a base 4?
DNA is more 2-based rather than 4, since you can have only 2 types of base pairs (AT and GC). However they can sit in 2 ways, which adds to overall 4 combinations.
What is base 5 called?
Quinary /ˈkwaɪnəri/ (base-5 or pental) is a numeral system with five as the base. A possible origination of a quinary system is that there are five digits on either hand.
What are the 5 bases of DNA?
Five nucleobases—adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U)—are called primary or canonical. They function as the fundamental units of the genetic code, with the bases A, G, C, and T being found in DNA while A, G, C, and U are found in RNA.
What is the largest four digit number in base four?
What is the 4 digit greatest number?
What is the largest four digit number in base nine?
Which number is the smallest?
0 is the smallest whole number. 1 is the smallest natural number.
What are the smallest and greatest 4 digit numbers?
The smallest four-digit number is 1000 and the greatest is 9999.
What is the largest four digit number in base sixteen?
So the largest number you can represent with 4 digits in base 16 is: Counting any higher than that would require that you utilize more digits. The very next number is 10000 in hexadecimal, or 65536 in decimal. It is a well-known value in computer science and is called “64K.”
What is the largest four digit number in base seven?
What is the largest six digit number in base sixteen?
What is the largest four digit number in base eight?
CAT Question In base 8, the largest number is 7777. It is equivalent to 4095 in decimal. The perfect square it is close to is 4096 = 64×64 and 3969 = 63×63. So the greatest four digit number which is a perfect square is 7601.
What is the highest octal number?
The highest three digit octal-number (77778) can represent 4095 binary digits.
- The octal number system uses 8 numbers from 0 – 7. (
- In octal number system the weight of the value of a digit will increase with power of 8.
- The decimal number can be converted to octal number by repeated division by 8 method .
What is the largest hexadecimal number?
What is the largest digit in the decimal number system?
