How is the complementary strand made? If the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. The enzyme DNA polymerase The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule. During this proces…DNA polymerase
Are the two strands of DNA identical or complementary?
The two strands are internally connected by hydrogen bonding between complementary bases. The two strands of DNA are not identical because their sequence of bases has to be complementary to each other.. Why DNA is a double helix? The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like ...
What are the complimentary bases of a strand of DNA?
Complementary bases are: adenine (A) and thymine (T), and cytosine (C) and guanine (G). So if one strand of DNA reads A-C-G-C-T-A, then the complementary strand is T-G-C-G-A-T. You can find the sequence of the mRNA transcript in the same way, by using the complements of the bases shown in the DNA sequence.
How many individual strands is DNA composed of?
Zooming in on DNA Structure
- A molecule of DNA consists of two strands that form a double helix structure. ...
- Each DNA strand is composed of nucleotides—units made up of a sugar (deoxyribose), a phosphate group, and a nitrogenous base. ...
- The sequences of nitrogenous bases on the two strands of a DNA molecule are complementary. ...
What are the complementary bases for DNA?
What are the complementary bases in DNA? either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA.
What are the letters in DNA?
What is the name of the group of molecules that contain guanine?

What is the complementary strand of dna for attgcaattggcgaa ... - Answers
C binds to G and T binds to A. Therefore the complementary DNA strand for ATT-GCA-ATT-GGC-GAA is: TAA-CGT-TAA-CCG-CTT
What is the complementary strand of DNA AATGCCAGTGGT? - Quora
Answer (1 of 3): Oh dear. Some wrong answers here. The complementary strand of 5′-AATGCCAGTGGT-3′ is 5′-ACCACTGGCATT-3′. Don’t forget that the two strands of a DNA double helix are reverse complements of each other — in other words, not only is A paired with T and G paired with C, but the orient...

Is one strand of DNA that is complementary to the other strand opposite or matching? I don't know what you mean by complementary, so I'll use an example.
What is the complementary strand of the DNA molecule ATC GGG GCT CAT ...
Answer (1 of 5): A and T are complementary So are G and C So obviously the only right answer is TAG CCC CGA GTA TTA The result of assigning the complement base pair by base pair It really is that simple, honestly, whether this is a high school bio homework question or not. Now if you needed...
What is complementary strand of DNA of the following single strand DNA ...
3'T-A-G-T-A-C-G-5' DNA is a double helix structure made of phosphate, sugar and 4 nitrogen bases. Your 4 bases are guanine (G), cytosine (C), adenine (A) and thymine (T). Now, your nitrogen bases actually come in pairs so remember your pairs as GC and AT which means that guanine pairs with cytosine and cytosine pairs with guanine and similarly with adenine and thymine. Now, you might be ...
What are the letters in DNA?
The letters A, T, C and G represent the nucleotides or nitrogenous bases that make up a strand of DNA: Adenine and guanine are a class of molecules called purines and cytosine and thymine are in a class called pyrimidines.
What is the name of the group of molecules that contain guanine?
Adenine and guanine are a class of molecules called purines and cytosine and thymine are in a class called pyrimidines. Adenine pairs with thymine and cytosine pairs with guanine. The two opposite DNA strands in the double helix are made of of these base pairs. Purines are larger than pyrimidines so consistent spacing is maintained by each base pair having a purine and a pyrimidine. The sequence along one strand is the "complement" of the sequence along the other strand, so that when two strands are bonded each base is paired with its complementary partner.
Which direction is the complementary strand of DNA bonded to?
One strand of a double-stranded DNA helix is oriented in the 5' (carbon of the deoxyribose molecule) to 3' direction, while the complementary strand it is bonded to is oriented in the 3' to 5' direction.
What is the structure of DNA?
a. She created many models of DNA based on what was known about its properties, and eventually figured out that the structure of DNA is a double helix.
What happens to DNA at the 3rd prime?
DNA nucleotides are always added to an existing strand at the 3-prime end. This means that during replication a leading and lagging strand are created.
What happens to DNA strands during replication?
During DNA replication, a complementary strand of DNA is made for each original DNA strand. Thus, if a portion of the original strand is CCTAGCT, then the new strand will be
Which scientist hypothesized that DNA was a double helix?
Chargaff hypothesized that DNA was a double helix, but he did not produce the image that proved this fact. b. Chargaff showed that adenine and thymine were found in equal percentages in DNA, but he did not know this was because of base-pairing.This answer is correct.
Which two elements were found in equal percentages in DNA?
b. Chargaff showed that adenine and thymine were found in equal percentages in DNA, but he did not know this was because of base-pairing.This answer is correct.
How many bases does DNA have?
A particular sequence of parent DNA has four purine bases and two pyrimidine bases. According to base-pairing rules, which of the following sequences could be formed during replication?
What are the letters in DNA?
The letters A, T, C and G represent the nucleotides or nitrogenous bases that make up a strand of DNA: Adenine and guanine are a class of molecules called purines and cytosine and thymine are in a class called pyrimidines.
