Transcription Quiz: Biology Trivia!

Explanation
RNA, or ribonucleic acid, is a molecule that is similar to DNA but has a different sugar molecule and a different base. The bases for RNA are adenine (A), uracil (U), cytosine (C), and guanine (G). Unlike DNA, which has thymine (T) as one of its bases, RNA replaces thymine with uracil. Therefore, the correct bases for RNA are A, U, C, and G.

Explanation
During transcription, mRNA is made from a DNA template. This process involves the enzyme RNA polymerase binding to the DNA strand and synthesizing a complementary mRNA strand by adding nucleotides that are complementary to the DNA sequence. The resulting mRNA molecule carries the genetic information from the DNA and will be used as a template for protein synthesis during translation. Therefore, the correct answer is that mRNA will make a copy of the DNA.

Explanation
The goal of transcription is to make a copy of DNA using mRNA. Transcription is the process by which the DNA sequence is converted into an RNA sequence, specifically mRNA. This mRNA molecule can then be used as a template for protein synthesis by ribosomes. Therefore, the correct answer is to make a copy of DNA using mRNA.

Explanation
The purpose of having mRNA is because the DNA cannot leave the nucleus. DNA is the genetic material that contains instructions for making proteins, but it is located within the nucleus of the cell. In order for these instructions to be carried out and proteins to be synthesized, a copy of the DNA sequence needs to be made and transported out of the nucleus. This is where mRNA comes in. mRNA is a molecule that carries the genetic information from the DNA to the ribosomes in the cytoplasm, where protein synthesis occurs. Therefore, mRNA acts as an intermediate messenger between the DNA and the protein synthesis machinery.

Explanation
The mRNA strand is complementary to the DNA strand. In RNA, the base thymine (T) is replaced by uracil (U). Therefore, the mRNA strand would have the same sequence as the DNA strand, except that each T in the DNA is replaced by U in the mRNA. So, the correct mRNA strand would be U A C C C C G C U.

Explanation
The given DNA sequence is T A G G C A T C A. In mRNA, the base T is replaced with A, the base A is replaced with U, the base G is replaced with C, and the base C is replaced with G. Therefore, the mRNA sequence would be A U C C G U A G U.

Explanation
The mRNA sequence is complementary to the DNA sequence and replaces thymine (T) with uracil (U). Therefore, the mRNA sequence for the given DNA sequence C C C G G G T T T A T A would be G G G C C C A A A U A U.

Explanation
Transcription is the process of synthesizing RNA from a DNA template. It takes place in the nucleus of a cell. Inside the nucleus, the DNA molecule is unwound and one of the DNA strands is used as a template to produce a complementary RNA molecule. This RNA molecule carries the genetic information from the DNA to the ribosomes, where it is used as a template for protein synthesis. The mitochondria, on the other hand, are responsible for energy production in the cell and do not play a direct role in transcription.
