How does the cell use both DNA and RNA to direct protein synthesis quizlet?

How does the cell use both DNA and RNA to direct protein synthesis quizlet?

During transcription, RNA polymerase binds to DNA and separates the DNA strands. RNA polymerase then uses one strand of DNA as a template from which nucleotides are assembled into a strand of RNA. During translation, the cell uses information from messenger RNA to produce proteins. protein.

How does the cell use DNA and RNA to direct protein synthesis?

During the process of transcription, the information stored in a gene’s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.

Does a cell require both DNA and RNA to make a protein?

Because many identical RNA copies can be made from the same gene, and each RNA molecule can direct the synthesis of many identical protein molecules, cells can synthesize a large amount of protein rapidly when necessary.

What is the role of RNA and DNA in protein synthesis?

DNA makes RNA makes Protein. The synthesis of proteins occurs in two sequential steps: Transcription and Translation. Transcription occurs in the cell nucleus and uses the base sequence of DNA to produce mRNA. The mRNA carries the message for making a specific protein out to the cytoplasm where translation occurs.

Why is Z-DNA left-handed?

Z-DNA (default scene) is a form of DNA that has a different structure from the more common B-DNA form.It is a left-handed double helix wherein the sugar-phosphate backbone has a zigzag pattern due to the alternate stacking of bases in anti-conformation and syn conformation.

Which of the following is a substance for DNA replication?

These include (1) DNA polymerase and DNA primase to catalyze nucleoside triphosphate polymerization; (2) DNA helicases and single-strand DNA-binding (SSB) proteins to help in opening up the DNA helix so that it can be copied; (3) DNA ligase and an enzyme that degrades RNA primers to seal together the discontinuously …

Which of the following is used by DNA polymerase as a substrate?

The substrates: DNA polymerase, reverse transcriptase, and telomerase use deoxyribonucleoside triphosphates as a substrate, whereas RNA polymerase uses ribonucleoside triphosphates. b.
