What is the new mRNA stand produced by this mutated gene?
The specific sequence of the new mRNA strand produced by a mutated gene will depend on the nature of the mutation. Mutations can cause changes in the coding region of the gene, leading to alterations in the mRNA sequence and potentially affecting the resulting protein or gene function. Further analysis and sequencing of the mutated gene would be required to determine the exact mRNA sequence.
What is mRNA?
A RNA copy of a DNA gene <--- Gradpoint/NovaNet Messenger RNA (mRNA) is a form of RNA that codes for amino acids. During transcription a sequence of mRNA is made from a corresponding sequence of DNA. In a eukaryote, the mRNA is then processed and sent outside the nucleus to be translated by a ribosome in the cytoplasm. As for a prokaryote (which has no nucleus), the mRNA is already in the cytoplasm and just needs to be translated by a ribosome also in the prokaryote's cytoplasm.
How is mRNA made in the process of protein synthesis?
mRNA is made during protein synthesis through a process called transcription. In transcription, the DNA sequence of a gene is copied into a complementary mRNA molecule by an enzyme called RNA polymerase. This mRNA molecule then carries the genetic information from the DNA to the ribosome, where it is used as a template to assemble amino acids into a protein.
What statement best compares the base sequence of an mRNA molecule with that of the cDNA made from the mRNA?
The base sequence of cDNA is complementary to the mRNA molecule from which it is synthesized. This means that the cDNA will have the same sequence as the mRNA, except that thymine in DNA is replaced with uracil in RNA.
A gene has the base sequence that starts with TCG GAC CAT CGAg b) What would be the mRNA base sequence formed from this DNA?
The mRNA sequence transcribed from the given DNA sequence is AGC CUG GUA GCU. The DNA base T pairs with A in mRNA, C pairs with G, G pairs with C, and A pairs with U.
What is the sequence of the mRNA made from the gene TTACAGGTCCCA?
The sequence of the mRNA transcribed from the DNA gene TTACAGGTCCCA would be complementary to the template strand of the DNA. Since mRNA is synthesized using uracil (U) instead of thymine (T), the corresponding mRNA sequence would be AAUGUCCAGGGU. This sequence reflects the direct transcription of the DNA template, replacing each thymine with uracil.

Further analysis and sequencing of the mutated gene would be required to determine the exact mRNA sequence.
What molecule contain anticodons?
The tRNA gene sequence is the anti-codon while mRNA is the codon sequence.
How is mRNA produced in a cell?
mRNA is produced through a process called transcription, which occurs in the nucleus of a cell. During transcription, the DNA sequence of a gene is copied into a complementary mRNA sequence by RNA polymerase enzyme. This mRNA transcript is then processed and modified before it is transported out of the nucleus to be translated into protein in the cytoplasm.
What is the new mRNA strand produced by a mutated gene?
The new mRNA strand produced by a mutated gene may contain errors in the sequence due to a change in the gene's DNA sequence. This can lead to changes in the resulting protein, affecting its structure or function. Mutations can range from single nucleotide changes to large deletions or insertions, altering the mRNA sequence accordingly.
Can a cell make a protein directly from gene?
Yes, a cell can make a protein directly from a gene through the process of transcription and translation. During transcription, the gene's DNA sequence is copied into a messenger RNA (mRNA) molecule. The mRNA then carries the genetic information to the ribosomes in the cell where translation occurs, resulting in the synthesis of a protein based on the mRNA sequence.
Proteins are made based on information stored in genes through what process?
Proteins are made based on information stored in genes through the processes of transcription and translation. During transcription, the DNA sequence of a gene is copied into messenger RNA (mRNA). This mRNA then travels to the ribosome, where translation occurs, converting the mRNA sequence into a specific amino acid chain, ultimately folding into a functional protein.
What is directly responsible for the sequence of amino acids in a protein?
The sequence of amino acids in a protein is directly determined by the sequence of nucleotides in the gene that codes for that protein. This process occurs during protein synthesis, where the genetic information is transcribed from DNA to mRNA and then translated into a specific sequence of amino acids.
What statement best compares the base sequence of an mRNA molecule with that of the cDNA made from the mRNA?
The base sequence of cDNA is complementary to the mRNA molecule from which it is synthesized. This means that the cDNA will have the same sequence as the mRNA, except that thymine in DNA is replaced with uracil in RNA.

The mRNA sequence transcribed from the given DNA sequence is AGC CUG GUA GCU. The DNA base T pairs with A in mRNA, C pairs with G, G pairs with C, and A pairs with U.

Section of DNA that forms a particular strand of messenger RNA?
A gene is a section of DNA that encodes instructions for building a particular protein. Transcription is the process by which a gene's DNA sequence is copied into messenger RNA (mRNA). The mRNA carries the genetic information from the DNA to the ribosome for protein synthesis.
