What is sense and antisense strand of DNA?

What is sense and antisense strand of DNA?

In double-stranded DNA, only one strand codes for the RNA that is translated into protein. This DNA strand is referred to as the antisense strand. The strand that does not code for RNA is called the sense strand. Antisense DNA is also known as noncoding DNA.

Is the sense strand the template strand?

Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.

What is difference between antisense and sense strand?

Sense strand contains the exact nucleotide sequence to the mRNA which encodes for a functional protein. The main difference between sense and antisense strand is that sense strand is incapable of being transcribed into mRNA whereas antisense strand serves as the template for the transcription.

Why is it called sense strand?

The DNA sense strand is called a “sense” strand not because it will be used to make protein (it won’t be), but because it has a sequence that corresponds directly to the RNA codon sequence. By this logic, the RNA transcript itself is sometimes described as “sense”.

Which strand of DNA is the coding strand?

nontemplate strand
The nontemplate strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule. In most organisms, the strand of DNA that serves as the template for one gene may be the nontemplate strand for other genes within the same chromosome.

Why is it called the antisense strand?

The second strand is called the antisense strand because its sequence of nucleotides is the complement of message sense. When mRNA forms a duplex with a complementary antisense RNA sequence, translation is blocked.

What is a sense strand?

Sense strand. In genetics, a sense strand, or coding strand, is the segment within double-stranded DNA that runs from 5′ to 3′, and which is complementary to the antisense strand of DNA, or template strand, which runs from 3′ to 5′.

What is the sense and antisense strand?

Sense and antisense are the two strands of DNA. The foremost between sense and antisense is, primarily based totally on transcription or on the strand that serves as template for mRNA, one of the strand is called sense whereas the alternative one is called antisense.

What strand of DNA is transcribed?

Simple diagram of transcription initiation. As in DNA replication, only one of the two DNA strands is transcribed. This strand is called the template strand, because it provides the template for ordering the sequence of nucleotides in an RNA transcript. The other strand is called the coding strand.

What does the RNA strand do?

Functionally, RNA’s most well-known function relates to protein synthesis . The instructions that DNA represents are for making proteins. Proteins are the building blocks of life and help to make other building blocks, such as carbohydrates or lipid structures. Think of DNA as an ancient book containing all the information of life.
