What is the sequence of bases in DNA?
ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases. Adenine pairs with thymine, and cytosine pairs with guanine.
What is the sequence from left to right of the complementary DNA strand?
Complementarity between two antiparallel strands of DNA. The top strand goes from the left to the right and the lower strand goes from the right to the left lining them up.
What is the sequence of bases on DNA strand B?
The sequence of bases on DNA can be in any order, and bases can include any from adenine, guanine, cytosine and thymine. The bases on DNA strand b will be complementary to those present on strand a.
Why is the sequence of bases in DNA important?
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases pair up with each other, A with T and C with G, to form units called base pairs.
What is A complementary DNA strand?
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template. From: Encyclopedia of Genetics, 2001.
What is the complementary strand of Acgtt?
Answer: Explanation:Uracil (U) is found in its place and complements adenine (A) instead. Therefore if the original DNA template strand read ACGT, the RNA strand will attach uracil to adenine so the complementary RNA strand will read UGCA.
What is the complementary DNA strand?
Complementary deoxyribonucleic acid (DNA) is DNA in which the sequence of the constituent molecules on one strand of the double stranded structure chemically matches the sequence on the other strand. In the chemical “lock and key” fit, an A on one strand always pairs with a T on the other strand. …
What would be the sequence of bases on the complementary strand?
Complementary sequence: Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.
What is the sequence of bases in mRNA?
If the sequence of bases in a section of DNA is ATCCGATT, what is the corresponding sequence of bases in mRNA? However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.
What makes up the backbone of a DNA strand?
Covalent bonds join the sugar of one nucleotide to the phosphate group of the next nucleotide, forming the DNA strand’s sugar-phosphate backbone. A nitrogenous base is an organic molecule that contains nitrogen and has the chemical properties of a base.
Which is base pair arises in complementary strands of DNA?
UAGGCUAA First, think about which base pairs arise in complementary strands of DNA: DNA → DNA adenine → thymine (A → T) thymine → adenine (T → A) cytosine → guanine (C → G) guanine → cytosine (G → C) However, mRNA does not consist of the same four bases as DNA.
How are the bases on each strand of RNA joined?
The bases on each strand are joined to the bases on the other strand with hydrogen bonds, but different bases have different chemical structures. Cytosine and thymine (and uracil in RNA) are pyrimidines, containing one ring. Adenine and guanine are purines, containing two rings.
