Answer #1

Ans:

The sequence of amino acids from a mRNA sequence CCGUGU is proline-Cysteine (Pro-Cys) because CCG codes for prolein and UGU codes for Cysteine.

The sequence of amino acids from a DNA  sequence AATGTT is leucine-glutamine (leu-Gln) because the template strand is the antisense strand, the sequence of mRNA is complementary to template strand. If the sequence of template strand is AATGTT, the sequence of mRNA is UUACAA. UUA codes for leucine and CAA codes for glutamine.

The start codon of a translation is AUG (occasionally GUG)

The stop codons are UGA, UAA and UAG.

Q2 An open reading frame (ORF) is a section of codons that begins with a start codon and ends with a stop codon. Each codon specifies for a specific amino acid. ORF is the part of a gene that after transcription into an mRNA gets translated into a protein. With the help of several translation factors and enzymes, ribosomes translate mRNAs into proteins. The following DNA sequence contains a complete open reading frame (ORF) of a short transcriptional unit. The...
