What does 5 and 3 mean in DNA?
Each end of DNA molecule has a number. One end is referred to as 5' (five prime) and the other end is referred to as 3' (three prime). The 5' and 3' designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.

Which sequences is complementary to a DNA strand with sequence 5 3?
The correct answer is c. 5' GTCTA 3'. The complementary strand will run in an antiparallel direction, that is, from 3' to 5'. In addition, cytosine…
What should be the complementary strand of 3 Atggcttga 5 *?
ATGGCTTGA…. 5'? Explanation: The complementary of A is T and for G is C, therefore the complementary sequence should be …. TACCGAACT….
How are complementary strands written?
Complementary strands Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions.
What is complementary base pairing in DNA?
Base pairing takes place between a purine and pyrimidine. In DNA, adenine (A) and thymine (T) are complementary base pairs, and cytosine (C) and guanine (G) are also complementary base pairs, explaining Chargaff's rules (Figure 7).

What are complementary strands?
Definition of 'complementary strand' 1. either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases. 2. a section of one nucleic acid chain that is bonded to another by a sequence of base pairs.
Which one of the following is the complementary sequence for the DNA with 5 ‘- contact 3?
If the sequence of one strand of DNA is written as follows: <br> 5-ATGCATGCATGCATGCATGCATGCATGC-3 <br> Write down the sequence of complementary strand in `5 to 4` direction….

Which of the following RNA sequences is complementary to 5 ‘- Cgtata 3?
The correct answer is c. 5' GTCTA 3'. The complementary strand will run in an antiparallel direction, that is, from 3' to 5'.
Which of the following is true about Z-DNA helix?
Which of the following is true about Z-DNA helix? It has more base pairs per turn than B-DNA.
How many forms of DNA are present?
three different types The three different types of DNA include: A-DNA. B-DNA. Z-DNA.
How do you write a complementary strand?
Complementary Sequence: Since DNA has two strands, every DNA sequence has a complementary sequence running parallel. In the complementary sequence, Adenine (A) is always paired with Thymine (T), and Cytosine (C) is always paired with Guanine (G).
What is 5 end and 3 end in DNA?
Each end of DNA molecule has a number. One end is referred to as 5' (five prime) and the other end is referred to as 3' (three prime). The 5' and 3' designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.
How do you write A complementary strand?
Complementary Sequence: Since DNA has two strands, every DNA sequence has a complementary sequence running parallel. In the complementary sequence, Adenine (A) is always paired with Thymine (T), and Cytosine (C) is always paired with Guanine (G).

What is the base sequence for 3 → 5 Strand?
According to complimentary base pairing, A pairs with T and C with G. For the given sequence, the complementary strand will be 3'- TACGTACGTACGTACGTACGTACGTACG − 5'. So, the sequence of the complimentary strand in 5' to 3' direction is 5'- GCATGCATGCATGCATGCATGCATGCAT− 3'.
What is the difference between B-DNA and Z-DNA?
DNA is a right-handed double helix composed of deoxyribonucleotides….Key Difference between B DNA and Z DNA.
| B DNA | Z DNA |

| Right-handed | Left-handed |
| Occurrence | |
| Common | Less common comparatively |
| Description of major and minor groove |
Where is Z form DNA found?
Z-DNA is a left-handed helical form of DNA in which the double helix winds to the left in a zigzag pattern. DNA containing alternating purine and pyrimidine repeat tracts have the potential to adopt this non-B structure in vivo under physiological conditions, particularly in actively transcribed regions of the genome.

What does 3 ‘- 5 mean in DNA?
Each end of DNA molecule has a number. One end is referred to as 5' (five prime) and the other end is referred to as 3' (three prime). The 5' and 3' designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.
Do humans have Z-DNA?
In human cells, Z-DNA was found to form in actively transcribed regions of the genome and was confirmed using ChIP-Seq (Shin et al. 2016).
What is the difference between A-DNA B-DNA and Z-DNA?
The key difference between B DNA and Z DNA is that the B DNA is the commonest form of DNA, which is a right-handed helix while the Z DNA is the long and thin version of B DNA, which is a left-handed helix. James Watson and Francis Crick in 1953 discovered the double helix structure of DNA.
What is Z-DNA helix?
Z-DNA is a left-handed helical form of DNA in which the double helix winds to the left in a zigzag pattern. DNA containing alternating purine and pyrimidine repeat tracts have the potential to adopt this non-B structure in vivo under physiological conditions, particularly in actively transcribed regions of the genome.
