Is the complementary strand transcribed?

During transcription, a strand of mRNA is made that is complementary to a strand of DNA. Transcription uses the sequence of bases in a strand of DNA to make a complementary strand of mRNA. Triplets are groups of three successive nucleotide bases in DNA. Codons are complementary groups of bases in mRNA.

Which strand is the complementary strand of DNA?

sense strand
Two strands of complementary sequence are referred to as sense and anti-sense. The sense strand is, generally, the transcribed sequence of DNA or the RNA that was generated in transcription, while the anti-sense strand is the strand that is complementary to the sense sequence.

Can both strands of DNA be transcribed?

Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand. Transcription ends when the RNA polymerase enzyme reaches a triplet of bases that is read as a “stop” signal.

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 a complementary strand of DNA example?

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 A complementary strand of DNA example?

Why are both the strands of DNA not transcribed?

(i) Both strands of DNA are not copied during transcription. One segment of the DNA would be coding for two different proteins, and this would complicate the genetic information transfer machinery. Second, the two RNA molecules if produced simultaneously would be complementary to each other.

What are two strands of DNA held together by?

Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.

What would be the complementary DNA bases for this strand Attgac?

Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine. To compliment the given strand, you’d have to choose the base that would pair with each individual nucleotide. For example, The pair to ACCTGAC would be TGGACTG.

What does complementary DNA strand mean?

Complementary strands. (Science: molecular biology) two single strands of dna in which the nucleotide Sequence is such that they will bind as a result of base pairing throughout their full length.

What is the complementary base pairing of DNA?

In DNA, the nitrogen bases are named guanine, cytosine, adenine, and thymine, and they will connect with each other by forming bonds (specifically, hydrogen bonds) with their hydrogen atoms. Guanine always bonds with cytosine, which makes them a pair of complementary bases.

What happens if both the strand of DNA are transcribed into RNA at same time?

It seems reasonable that only one strand is used, because transcription of RNA from both strands would produce two complementary RNA strands from the same stretch of DNA, and these strands presumably would produce two different kinds of protein (with different amino acid sequences).

How to write the complementary strand of DNA?

Practice writing a strand of the complementary strand of dna and completing a strand of messenger RNA. When you have DNA, adenine pairs with thymine, and cytosine pair with guanine. Whenever you have mRNA uracil replaces thymine.

Which is strand of DNA is transcribed in RNA synthesis?

1 When transcription starts, DNA must unwind, aided by RNA polymerase, which catalyzes the process. 2 In transcription only one of the DNA strands is transcribed, the strand that has the initiator sequence. 3 mRNA that is transcribed is normally a copy of the sense strand, however, it is the antisense strand that is transcribed.

Where does transcription take place in a prokaryotic cell?

Transcription in prokaryotes (and in eukaryotes) requires the DNA double helix to partially unwind in the region of mRNA synthesis. The region of unwinding is called a transcription bubble. Transcription always proceeds from the same DNA strand for each gene, which is called the template strand.

How is transcription aided by RNA polymerase enzyme?

The process of transcription is aided by the RNA polymerase enzyme, which copies the right sequences on the DNA template to produce a complementary RNA copy of the gene. The basic mechanism of transcription is the same in both eukaryotes and prokaryotes, however, it may differ in a number of ways between them.
