The DNA template strand is used to encode double-stranded RNA.
. The RNA is called messenger RNA because it carries the message or genetic information from the DNA to the ribosomes where the information is used to make proteins. Namely the DNA molecule unwinds at the site of the gene to be transcribed. The correct answer is A.
5-GGCATGGCAATATTGTAGTA-3 3-CCGTACCGTTATAACATCAT-5 Given this information a. For the original DNA strand of 3- TACCGAGATGTATCAACT -5 The transcribed mRNA would be 5- AUGGCUCUACAUAGUUGA-3. Altetnatively the atom from the same excited state can make a transition to the second.
Before leaving the nucleus mRNA is protected with which of the following. E A B and C are true. In transcription an mRNA messenger RNA intermediate is transcribed from one of the strands of the DNA molecule.
B Extensive RNA processing is required before prokaryotic transcripts can be translated. 7-21 Imagine that an RNA polymerase is transcribing a segment of DNA that contains the following sequence. MRNA binds directly to amino acids during translation.
M RNA is transcribed from a DNA template. Both DNA strands are used to transcribe a single gene. 5 -AGTCTAGGCACTGA-3 3 -TCAGATCCGTGACT-5 Page 6 of 29 A.
DNA is transcribed by an enzyme called RNA polymerase. After transcription the pre-mRNA is spliced and modified to produce mRNA c. For a protein-coding gene the RNA copy or transcript carries the information needed to build a.
The DNA nontemplate strand is used to encode single-stranded RNA. The formation of RNA from the DNA in the nucleus with the help of RNA polymerase enzyme is called transcription. 7-19 The following segment of DNA is from a transcribed region of a chromosome.
MRNA attaches to a ribosome. A Translation can begin while transcription is still in progress. The goal of transcription is to make a RNA copy of a genes DNA sequence.
Transcription is the first step in gene expression in which information from a gene is used to construct a functional product such as a protein. 7-20 You have a segment of DNA that contains the following sequence. If the polymerase is transcribing from this segment of DNA from left to right which strand top or bottom is the template.
B State which of the DNA strands the RNA synthesizing enzyme used as template for the transcription process. This makes option D correct answer. MRNA after processing moves from nucleus to the cytoplasm d.
5-ACCGAAUGGAGUCGUUAAUUAA-3 a Draw both strands of the segment of DNA that this mRNA was transcribed from. C Prokaryotic cells have complicated mechanisms for targeting proteins to the appropriate cellular organelles. B Extensive RNA processing is required before prokaryotic transcripts can be translated.
A-U Adenine to Uracil T-A Thymine to Adenine C-G Cytosine to Guanine G-C Guanine to Cytosine. In transcription the information stored in the DNA is copied in the RNA so that it will form the protein in a later process called translation. RNA and DNA use complementary coding where base pairs match up similar.
This excited atom can make a transitionn to the first excited state by successive emission of two photons of energies 1020 eV and 170 eV respectively. Uracil replaces thymine in RNA. C Prokaryotic cells have complicated mechanisms for targeting proteins to the appropriate cellular organelles.
There are three main steps to the process of DNA transcription. Consider the following piece of messenger RNA. 13 Which of the following statements are true about protein synthesis in prokaryotes.
All genes are transcribed from the same strand of DNA. MRNA is transcribed from a DNA template b. 12 Which of the following statements are true regarding transcription in most organisms.
A All genes are transcribed from the same strand of DNA b The DNA template strand is used to encode double- stranded RNA. RNA polymerase catalyzes the formation of an RNA molecule or transcript based on complementarity with DNA. The transcription would utilize complimentary base pairing rules for DNA to RNA.
Specific nucleotide sequences tell RNA polymerase where to begin and where to end. Which of the following represents an RNA strand that would be transcribed from the DNA strand above. You know that RNA polymerase moves from left to right along this piece of DNA that the promoter for this gene is to the left of the DNA shown and that this entire region of DNA is made into RNA.
In RNA Adenine bind with the uracil. RNA Polymerase Binds to DNA. C The DNA non-template strand is used to encode single- stranded RNA d Both DNA strands are used to transcribe a single gene.
The RNA sequence of given DNA strand would be UACGGAUCCUG. A hydrogen like species atomic number Z is present in a higher excited state of quantum number n. The RNA nucleotide sequence is complementary to that of DNA template strand except the presence of uracil in place of thymine.
D Only A and B are true. Which of the following represents a sequence of bases as they might. A 3 poly-adenine tail.
As we know that adenine base pairs with thymine and guanine with cytosine. That is a single strand of RNA is transcribed from one of the strands of a DNA helix. Which of the following is a stop sequence at the end of the DNA strand to stop adding to the sequence.
5-GGACTAGACAATAGGGACCTAGAGATTCCGAAA-3 3-CCTGATCTGTTATCCCTGGATCTCTAAGGCTTT-5 You know that the RNA transcribed from this segment contains the following sequence. RNA molecules originate from a DNA template through the process of transcription. MRNA is transcribed from DNA in the cytoplasm.
C Using the codon table give the amino acid sequence of the protein. Different genes may be transcribed from different strands of DNA.
