The
process by which DNA is copied to RNA is
called transcription, and that by which RNA is used to produce proteins is called translation.
What is difference between transcription and translation?
Hint: Transcription is the process of copying a gene’s DNA sequence to make an RNA molecule and translation is the process in which proteins are synthesized after the process of transcription of DNA to RNA in the cell’s nucleus. …
Translation synthesizes proteins from RNA copies
.
What is meant by transcription and translation?
Transcription and translation take
the information in DNA and use it to produce proteins
. Transcription uses a strand of DNA as a template to build a molecule called RNA. … During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
What is transcription in simple terms?
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.
What is translation in DNA?
Translation is
the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis
. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.
What are 3 steps of translation?
Translation of an mRNA molecule by the ribosome occurs in three stages:
initiation, elongation, and termination
.
What are the steps in translation?
Steps of Translation
There are three major steps to translation:
Initiation, Elongation, and Termination
. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5′ end of mRNA. It then moves in the 5′ → 3′ direction.
What are the similarities and differences between transcription and translation?
Transcription is
the synthesis of RNA from a DNA template where the code in the DNA is converted into
a complementary RNA code. Translation is the synthesis of a protein from an mRNA template where the code in the mRNA is converted into an amino acid sequence in a protein.
What are the end products of translation?
The amino acid sequence
is the final result of translation, and is known as a polypeptide. Polypeptides can then undergo folding to become functional proteins.
What happens during translation?
During translation,
ribosomal subunits assemble together like a sandwich on the strand of mRNA
, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.

What is the main goal of transcription?
Overview of Transcription. Transcription
uses the sequence of bases in a strand of DNA to make a complementary strand of mRNA
. Triplets are groups of three successive nucleotide bases in DNA. Codons are complementary groups of bases in mRNA.
What are the 6 steps of transcription?
- Initiation. Transcription is catalysed by the enzyme RNA polymerase, which attaches to and moves along the DNA molecule until it recognises a promoter sequence. …
- Elongation. …
- Termination. …
- 5′ Capping. …
- Polyadenylation. …
- Splicing.
What are the 4 steps of translation?
Translation happens in four stages:
activation (make ready), initiation (start), elongation (make longer) and termination (stop)
. These terms describe the growth of the amino acid chain (polypeptide). Amino acids are brought to ribosomes and assembled into proteins.
What are the 4 pieces needed for translation?
- They must be recognized by the correct aminoacyl synthetase.
- They must be recognized by ribosomes.
- They must bind to the correct sequence in mRNA.
What are required for translation?
The key components required for translation are
mRNA, ribosomes, and transfer RNA (tRNA)
. During translation, mRNA nucleotide bases are read as codons of three bases. Each codon codes for a particular amino acid.
