What else can I help you with?
Which of these statements does not describe introns?
Non-expressed
Is the highest percentage of non coding DNA is found in bacteria or prokaryotes?
The highest percentage of non-coding DNA is found in eukaryotes, not in bacteria or prokaryotes. In eukaryotic organisms, non-coding DNA makes up a larger portion of the genome compared to coding DNA. This non-coding DNA includes regions such as introns, repetitive sequences, and regulatory elements.
Chromosome 22 contains long stretches of DNA that do not code for proteins?
Yes, chromosome 22 contains regions of non-coding DNA, including genes that encode for non-coding RNAs, regulatory elements, and repetitive DNA sequences. These non-coding regions play important roles in gene regulation and genome stability.
What is the technique that identifies and replicates the non-coding gene sequences in a strand of DNA?
The technique that identifies and replicates non-coding gene sequences in DNA is known as polymerase chain reaction (PCR). PCR is a widely used method that allows researchers to selectively amplify specific regions of DNA, including non-coding sequences, for further analysis. By using specific primers that target the non-coding regions, PCR can generate multiple copies of these sequences for various applications in genetic research.
Is all DNA considered coding DNA?
No, not all DNA is considered coding DNA. Coding DNA contains the instructions for making proteins, while non-coding DNA includes regulatory sequences, introns, and other regions that do not directly code for proteins. Non-coding DNA plays important roles in gene regulation and other cellular functions.
What are the regions of DNA called that code for protein?
The coding regions of many eukaryotic genes are interrupted by non-coding sequences known as INTRONS. They are stretches of DNA whose transcripts are absent from mature mRNA product.
Which of these statements does not describe introns?
Non-expressed

The parts of DNA that provide the code for proteins are the?
Exons are the parts of DNA that provide the code for proteins. They are the coding regions of genes that are transcribed into messenger RNA and translated into proteins. The exons are separated by introns, which are non-coding regions of DNA.
What is non-coding DNA?
Non-coding DNA, also known as non-coding regions or junk DNA, refers to segments of DNA that do not code for proteins. While once thought to have no biological function, non-coding DNA is now known to play roles in gene regulation, chromosome structure, and evolutionary processes.
What is the technique that identifies and replicates the non-coding gene sequences in a strand of DNA?
The technique that identifies and replicates non-coding gene sequences in DNA is known as polymerase chain reaction (PCR).

When you read a DNA sequencing gel from the bottom to the top is what you read called the coding strand or the non-coding strand?
When reading a DNA sequencing gel from bottom to top, you are reading the sequence of the complementary non-coding strand of DNA. This is because the gel displays the sequence of bands corresponding to the bases in the DNA template strand, which is the non-coding strand.
Is all DNA considered coding DNA?
No, not all DNA is considered coding DNA. Coding DNA contains the instructions for making proteins, while non-coding DNA includes regulatory sequences, introns, and other regions that do not directly code for proteins. Non-coding DNA plays important roles in gene regulation and other cellular functions.
Which has more mutation coding or non-coding genes?
First of all a gene by definition codes for something so there is no such thing as a "non coding gene". To your question non-coding DNA is no more prone to mutation. A mutation in a non-coding region is far more likely to passed onto offspring because a mutation has no effect on the organism that gets it. A mutation in a gene is more likely to be bad thing than beneficial. So over time (many generations) there are more differences in non coding regions of DNA between individuals. This why DNA fingerprinting looks at differences in non coding regions between people to find unique profiles.
What technique take advantage of repeating DNA sequences that do not code for proteins?
DNA fingerprinting
Which regions of DNA are transcribed to RNA and then translated to form a polypeptide?
The regions of DNA that are transcribed to RNA are called exons. These exons will then be spliced together to form messenger RNA (mRNA), which will be translated into a polypeptide. Introns are the non-coding regions of DNA that are removed during the splicing process and are not translated into protein.
