What else can I help you with?
What are exons and introns?
Intronsare intervening sequence of DNA; does NOT code for a protein.Exons are expressed squence of DNA; codes for a protein.
What is the process by which the expressed sequence of DNA codes for a protein?
The process by which the expressed sequence of DNA codes for a protein is called protein synthesis. This process involves two main steps: transcription, where the DNA sequence is copied into a messenger RNA (mRNA) molecule, and translation, where the mRNA is used as a template to assemble amino acids into a protein.
Does mRNA contain thymine in its nucleotide sequence?
No, mRNA does not contain thymine in its nucleotide sequence. Instead, mRNA contains uracil in place of thymine.
How many reading frames are possible for a sequence of mRNA?
There are three possible reading frames for a sequence of mRNA.
Does mRNA contain uracil or thymine in its nucleotide sequence?
mRNA contains uracil in its nucleotide sequence, not thymine.
What is the sequence of mrna that is expressed after processiNG?
After processing, the mRNA sequence consists of exons, which are the expressed regions that code for proteins, joined together after the removal of introns. This mature mRNA is then translated into a protein by ribosomes in the cytoplasm.
Sequence in mrna that is not expressed as a protein?
introns
Sequence in mRNA is not expressed as proteins?
introns
What are exons and introns?
Intronsare intervening sequence of DNA; does NOT code for a protein.Exons are expressed squence of DNA; codes for a protein.
What are the three steps by which proteins are coded and synthesized?
Transcription: the DNA sequence is transcribed into mRNA in the nucleus. mRNA Processing: the pre-mRNA is modified and processed into mature mRNA, which is then transported to the cytoplasm. Translation: the mRNA is translated into a specific amino acid sequence by ribosomes in the cytoplasm to synthesize a protein.

This process involves two main steps: transcription, where the DNA sequence is copied into a messenger RNA (mRNA) molecule, and translation, where the mRNA is used as a template to assemble amino acids into a protein.
DNA sequence acgtt will give what mRNA base sequence?
The mRNA base sequence corresponding to the DNA sequence acgtt is ugcaa. The mRNA sequence is complementary to the DNA sequence, with thymine (T) in DNA being replaced by uracil (U) in mRNA.
What is an intervening sequence of DNA that is not expressed called?
An intervening sequence of DNA that is not expressed is called an intron. Intron sequences are removed during RNA processing, while the remaining expressed sequences are known as exons.
A mutation occurs in a cell. Which sequence best represents the correct order of the events involved for this mutation to affect the traits expressed by this cell?
The correct sequence of events for a mutation to affect the traits expressed by a cell is as follows: first, the mutation changes the DNA sequence of a gene. Next, this altered DNA is transcribed into messenger RNA (mRNA). Then, the mRNA is translated into a protein. Finally, the change in the protein can lead to a modified phenotype or trait expressed by the cell.
Does mRNA contain thymine in its nucleotide sequence?
No, mRNA does not contain thymine in its nucleotide sequence. Instead, mRNA contains uracil in place of thymine.
How many reading frames are possible for a sequence of mRNA?
There are three possible reading frames for a sequence of mRNA.
Does mRNA contain uracil or thymine in its nucleotide sequence?
mRNA contains uracil in its nucleotide sequence, not thymine.
