What is leader sequence in mRNA?

The region of a messenger RNA (mRNA) molecule that precedes the coding sequence of a gene is called the ‘leader sequence’. This region is also known as the ‘five prime untranslated region’ (Figure 1) of the mRNA. They are involved in the regulation of gene expression in eukaryotes and prokaryotes.

What is the correct sequence of mRNA?

mRNA codons are read from 5′ to 3′ , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. Translation involves reading the mRNA nucleotides in groups of three; each group specifies an amino acid (or provides a stop signal indicating that translation is finished).

What is a leader sequence in a protein?

Signal sequence; the N-terminal portion of a secretory or membrane protein that assists it across the membrane of the rough endoplasmic reticulum, where it is synthesized, but which is cleaved from the protein even before the synthesis of the protein is complete.

Where is the leader sequence?

Leader sequences are polynucleotide regions located between the promoter and the coding region and are involved in the regulation of gene expression.

What is the mRNA sequence of Tacaccttggcgacgact?

Question: Original DNA sequence: TACACCTTGGCGACGACT mRNA sequence: AUGUGGAACCGCUGCUGA Amino Acid Sequence: MET -TRP- ASN -ARG -CYC – (STOP) Mutation to original DNA TACGACCTTGGCGACGACT 1.

How do you find the sequence of an Anticodon?

Each tRNA has a set of three bases on it known as an anti-codon. The anti-codon matches complementary bases in the mRNA sequence. To determine the overall anti-codon sequence that will match a strand of mRNA, simply retranscribe the RNA sequence; in other words, write out the complementary bases.

What is Leader region?

a sequence of NUCLEOTIDES at the 5′-END of MESSENGER RNA (and on DNA), UPSTREAM of the start CODON for TRANSLATION. This sequence contains the RIBOSOME BINDING SITE but is not normally translated into a part of the PROTEIN of the GENE. In some cases it contains a regulatory region called an ATTENUATOR.
