Question

Answer

The strand of DNA that forms mRNA is called the template strand or the antisense strand. During transcription, the DNA molecule unwinds, and one of the strands (the template strand) is used as a template to synthesize a complementary RNA molecule, which is called messenger RNA (mRNA). The other strand of DNA, which is not used as a template during transcription, is called the coding strand or the sense strand because it has the same sequence as the mRNA molecule (except for the presence of thymine instead of uracil).

Answer

Both C and D are correct

Answer

Tamplate strand or noncoding strand  that form mRNA because protein formation information in coding strand if we use coding as template then it produced complementary strand just like noncoding strand so there are no information in that strand so we use noncoding as a template  .

Answer

The strand of DNA that forms mRNA is called the template strand. This is because the template strand serves as a guide or template for the synthesis of mRNA during the process of transcription.

**Explanation:**

During transcription, a DNA molecule is used as a template to synthesize a complementary mRNA molecule. This process occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. The DNA molecule consists of two strands, known as the template strand and the coding strand.

1. **Template Strand:**
- The template strand is the DNA strand that is used as a template for the synthesis of mRNA.
- It has a complementary sequence to the mRNA molecule that will be synthesized.
- The template strand runs in the 3' to 5' direction.
- The enzyme RNA polymerase binds to a specific region of the template strand called the promoter region and starts synthesizing mRNA in the 5' to 3' direction.

2. **Coding Strand:**
- The coding strand, also known as the sense strand, has the same sequence as the mRNA transcript, except that thymine (T) is replaced by uracil (U) in the mRNA.
- The coding strand runs in the 5' to 3' direction and is not directly involved in mRNA synthesis.

3. **Antisense Strand:**
- The antisense strand, also known as the non-coding strand or the non-template strand, has the same sequence as the mRNA transcript, except that thymine (T) is replaced by uracil (U) in the mRNA.
- The antisense strand runs in the 3' to 5' direction and is not directly involved in mRNA synthesis.

4. **Lagging Strand:**
- The lagging strand is a term used in DNA replication, not in transcription.
- During DNA replication, the lagging strand is synthesized discontinuously in small fragments called Okazaki fragments.

In summary, the strand of DNA that is used as a template for the synthesis of mRNA during transcription is called the template strand. It has a complementary sequence to the mRNA molecule and serves as a guide for the synthesis of mRNA by RNA polymerase.

Answer

Template strand

Answer

D) Template strand :-
The term template strand refers to the DNA sequence that can duplicate itself during mRNA synthesis. The cell uses a non-coding/antisense DNA sequence as a template to produce mRNA.

Answer

Both antisence and template strand

Answer

Both c and d

Answer

C

Answer

Both C and D because it is template for the newly synthesize strand

Answer

Templete strand or Antisense strand or non-cooding strand of DNA participate  in transcription process to forms  a mRNA which is important for Translation.

Answer

Option c and d both are correct

Answer

A
