What mRNA codon is transcribed from the DNA sequence TTG?

What mRNA codon is transcribed from the DNA sequence TTG?

Solution

Asparagine (Asn) Histidine (His)
mRNA codon AAU or AAC CAU or CAC
DNA TTA or TTG GTA or GTG
tRNA anticodon UUA or UUG GUA or GUG

What amino acid does mRNA GCC code for?

Amino Acid Coding DNA Strand Base Triplets Not Transcribed Template DNA Strand Base Triplets Transcribed
alanine GCT, GCC, GCA, GCG CGA, CGG, CGT, CGC
arginine CGT, CGC, CGA, CGG AGA, AGG GCA, GCG, GCT, GCC TCT, TCC
asparagine AAT, AAC TTA, TTG
aspartic acid GAT, GAC CTA, CTG

What is an mRNA sequence?

Codons in an mRNA are read during translation, beginning with a start codon and continuing until a stop codon is reached. 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. The mRNA sequence is: 5′-AUGAUCUCGUAA-5′

What is the mRNA sequence for the template strand?

DNA Coding Strand (Codons) 5′ > > > – – – – – – T T C – – – – – – > > > 3′

What is the strand of mRNA?

Messenger RNA (mRNA) is a subtype of RNA. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides known as ribonucleic acid, and is single-stranded.

Does the coding strand make mRNA?

For protein synthesis, messenger RNA must be made from one strand of DNA called the template strand. The other strand, called the coding strand, matches the messenger RNA in sequence except for its use of uracil in place of thymine.

Does mRNA have the same sequence as DNA?

The RNA to which the information is transcribed is messenger RNA (mRNA). Since the other strand of the DNA has bases complementary to the template strand, the mRNA has the same sequence of bases at the upper strand of DNA shown above (with U substituted for T) , which is called the coding strand.

What is the template strand in DNA replication?

A template strand is the term that refers to the strand used by DNA polymerase or RNA polymerase to attach complementary bases during DNA replication or RNA transcription, respectively; either molecule moves down the strand in the 3′ to 5′ direction, and at each subsequent base, it adds the complement of the current …

What is the template for 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 steps to protein synthesis?

It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.

What is difference between transcribe and translation?

Transcription, simply put, is documenting something into written form. For example, the process of listening to a recording of, say, an interview or a lecture and then transcribing into a readable document is transcription. Whereas translation would be converting text into another language.

How is translation accomplished?

Protein synthesis is accomplished through a process called translation. After DNA is transcribed into a messenger RNA (mRNA) molecule during transcription, the mRNA must be translated to produce a protein. In translation, mRNA along with transfer RNA (tRNA) and ribosomes work together to produce proteins.
