What is transcription in DNA quizlet?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Transcription takes place in the nucleus!
What does the three letter example ATC in DNA codes for?
Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T) — in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.
Which of the following is not a component required for transcription?
The correct answer is a). All of the components listed are required for transcription EXCEPT a primer.
Does transcription make DNA?
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene’s DNA sequence.
Why is transcription regulated?
Transcriptional regulation is a critical biological process that allows the cell or an organism to respond to a variety of intra- and extra-cellular signals, to define cell identity during development, to maintain it throughout its lifetime, and to coordinate cellular activity.
What happens if transcription does not occur?
If a gene is not transcribed in a cell, it can’t be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.
What is blank DNA called?
mRNA, transcription, nucleus. Fill in the Blank: In protein synthesis, one of the unwound strands of DNA forms a complementary strand called blank. This process is called blank and takes place in the blank of the cells.
What is made during transcription?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA.
