Which Molecule Is Made During The Process Of Transcription? - Fixanswer

The molecule that results from translation is

protein —

or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.

What is the starting molecule for transcription?

The process of transcription begins when an enzyme called

RNA polymerase (RNA pol)

attaches to the template DNA strand and begins to catalyze production of complementary RNA.

Is RNA a copy of DNA?

RNA is

synthesized from DNA

by an enzyme known as RNA polymerase during a process called transcription. The new RNA sequences are complementary to their DNA template, rather than being identical copies of the template. RNA is then translated into proteins by structures called ribosomes.

Is DNA replicated in transcription?

The mechanism of transcription has parallels in that of

DNA replication

. … Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand.

What is produced in transcription?

Transcription is the process by which the information in a strand of DNA is copied into a

new molecule of messenger RNA (mRNA)

. … The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.

What is produced in translation?

In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a

specific amino acid chain, or polypeptide

. The polypeptide later folds into an active protein and performs its functions in the cell.

What enzyme does translation use?

Translation is catalyzed by a large enzyme called

a ribosome

, which contains proteins and ribosomal RNA (rRNA). Translation also involves specific RNA molecules called transfer RNA (t-RNA) which can bind to three basepair codons on a messenger RNA (mRNA) and also carry the appropriate amino acid encoded by the codon.

What are the 3 main steps of transcription?

It involves copying a gene’s DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages:

initiation, elongation, and termination

.

What are the four steps of transcription?

Initiation. The DNA molecule unwinds and separates to form a small open complex.
Elongation. RNA polymerase moves along the template strand, synthesising an mRNA molecule.
Termination. In prokaryotes there are two ways in which transcription is terminated.
Processing.

Where is RNA found?

Comparison DNA RNA	Location DNA is found in the nucleus, with a small amount of DNA also present in mitochondria. RNA forms in the nucleolus , and then moves to specialised regions of the cytoplasm depending on the type of RNA formed.

What is RNA main function?

The central dogma of molecular biology suggests that the primary role of RNA is

to convert the information stored in DNA into proteins

.

Where are introns found?

Introns are found in

the genes of most organisms and many viruses

and can be located in a wide range of genes, including those that generate proteins, ribosomal RNA (rRNA) and transfer RNA (tRNA).

Where does DNA transcription occur?

In eukaryotes, transcription and translation take place in different cellular compartments:

transcription takes place in the membrane-bounded nucleus

, whereas translation takes place outside the nucleus in the cytoplasm. In prokaryotes, the two processes are closely coupled (Figure 28.15).
