Why does protein-coding genes almost never occur in multiple copies?Group of answer choicesThe repeated transcription of a few mRNA transcripts provides adequate amounts of most proteinsThe repeated transcription of a few tRNA transcripts provide adequate amounts of most proteinsThe repeated transcription of a few rRNA transcripts provide adequate amounts of most proteinThe repeated translation of a few mRNA transcripts provide adequate amounts of most proteins

Why does protein-coding genes almost never occur in multiple copies?

Explain how a single gene can produce many different proteins.

What is one cause for the 21,000 protein encoding sequences in the human genome producing between 200,000 and 1 million different proteins?Group of answer choicesalternative splicingCNVsrestriction sitesSNPs

The genetic code is said to be degenerate because there are 64 different codons, but translation produces only 20 unique amino acids.  The degeneracy of the genetic code is due to which mechanism?A.Exclusion of protein coding regions from mature mRNAB.Errors during tRNA chargingC.Ambiguity of the tRNA for the amino acidD.Nontraditional base pairing of the anticodon with the third base of the codon

What does it mean that the genetic code is redundant? That each codon codes for more than one amino acid That each codon can bind to more than one anticodon That most amino acids are coded by more than one codon That each tRNA anticodon can be attached to multiple different amino acids None of the above
