Each of these letters stands for a base (which is part of one nucleotide). Therefore because there are 12 bases, there would be 12 nucleotides in the strand.
The complementary strand for CGATTAC would be GCTAATG. C and G are always paired together, and A and T are always paired together.
tRNA does not copy a strand of DNA - that is what mRNA does.So for the DNA strand ATT-CGA-CCT-ACG:the mRNA strand would be UAA-GCU-GGA-UGCtRNA is responsible for carrying the correct amino acid to match up with the codon (three letter code) on the mRNA. The first codon here is UAA - which is a stop codon - meaning the peptide chain being created will not proceed beyond this.
Amino acids are formed by translating mRNA codons, not directly from DNA. In this DNA sequence, there are no stop codons present. It would be necessary to transcribe this DNA sequence into mRNA and then translate it into amino acids.

The sequence of nucleotides of the complementary strand will be the nucleotides which bind to the nucleotides of the template. In DNA, adenine binds to thymine and cytosine binds to guanine. The complementary strand will therefore have an adenine where the template strand has a thymine, a guanine where the template has a cytosine, etc. For example: If the template strand is ATG-GGC-CTA-GCT Then the complementary strand would be TAC-CCG-GAT-CGA
How many nucleotides are in one full twist of the DNA molecule?
To determine the first three nucleotides of the complementary RNA strand, you need to match the DNA bases with their RNA counterparts. In DNA, adenine (A) pairs with uracil (U) in RNA, thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). If the first three nucleotides of the DNA strand are, for example, A, T, and C, the complementary RNA strand would have U, A, and G as its first three nucleotides.
The restriction enzyme would cut between the nucleotides A and G on one strand and between the nucleotides C and T on the other strand to produce the fragment with the sequence AAGCTT.
G=C, G=C, T=A, A= T So, to answer the question: CGGTAAC
RNA is composed of a single strand of nucleotides, which are typically represented by the letters A, U, G, and C. Therefore, RNA consists of one chain of nucleotides.
During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.
A strand of DNA is a long polymer composed of four different types of nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). These nucleotides are connected in a specific sequence to encode genetic information.
It not 1, but four components that make up the strand. These 4 nucleotides are guanine, cytosine, thymine, and adenine (G-C-T-A)
During DNA replication, nucleotides are added to the 3' end of a DNA strand by an enzyme called DNA polymerase. This enzyme attaches new nucleotides to the existing strand in a complementary manner, following the base pairing rules (A with T, and G with C). The 3' end of the DNA strand provides a free hydroxyl group (-OH) that allows the DNA polymerase to add the new nucleotide, extending the DNA strand in the 5' to 3' direction.
It would be ATCAGT. A=T T=A G=C C=G for all the DNA sequences the complementary strand would be the opposite.
In DNA, the complementary strand would be: GGATCAGTAC.
