Answer =
k. defination of
Codon = Is defined as," a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA."
example - AUG ,CCG, CGC etc.
anti-codon = Is defined as,"a sequence of three nucleotides which together forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA."
example - UAC is anticodon which is a complementary to AUG codon in messenger RNA.
Transcription = is defined as," is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Translation = is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
REdundancy =Is defined as," is the phenomenon in which the same amino acid residue can be encoded by multiple codons."
example - phenylalanine is encoded by UUU, UUC codons.

Complete a concept map of translation, indicate where it takes place, and describe what will happen if the anticodon is not attached to transfer RNA. A)DNA unzips ?transcription of mRNA ? mRNA leaves nucleus ? mRNA binds to ?ribosome ? tRNA brings in amino acid? tRNA anticodon binds to codon on mRNA ? peptide bond binds amino acids to form protein ? transport of the amino acids to the mRNA by tRNA continues until the mRNA translation is completed. This...

Place the following steps of TRANSLATION in the correct order for EUKARYOTES. The ribosome reaches a stop codon. A release factor binds and causes the release of the new polypeptide, along with the mRNA. The ribosome dissociates. v Acharged tRNA with a matching anticodon binds the mRNA codon in the A site. ✓ The ribosome moves exactly 3 nucleotides toward the 3* end of the mRNA. The small ribosomal subunit uses rRNA to bind to the Kozak sequence, which places...

In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...
