The genetic code is non-overlapping. This means:

Group of answer choices

A. Each nucleotide is used in one codon

B. Each nucleotide can be used in only two codons

Each nucleotide can be used in one to three codons

Homework Answers

Answer #1

ANS . Genetic code is the relationship between the sequence of nucleotides on mRNA and sequence of amino acids in the polypeptide .The genetic codes features are -

1. The codons are triplet , out of 64 codons , 61 code for 20 amino acids and 3 codons (UAA,UGA,UAG) donot code for any amino acid hence act as stop codons.

2. One codon codes for only one particular amino acid hence code is unambigous

3. Some amino acids are coded by more than one codon hence code is degenerate

4. The codon is commaless

5. The genetic code is nearly universal

6. The genetic code is non over lapping because each codon is read in a sequence , separate from the codon before it and after it .Codons donot share their bases hence non overlapping. so, correct option is( A ) each nucleotide is used in one codon means a single nucleotide can not be the end of one codon and beginning of next codon.

1- Which of the following statements about the use of synthetic polynucleotides in cracking the genetic code is true? Group of answer choices Particular codons are generated in predictable ratios with random RNA polymers containing specific ratios of different nucleotides. Poly(A) RNA directs the synthesis of only polylysine in vitro. Three different amino acids are incorporated into peptides when synthetic polymers of only one nucleotide are used to synthesize the RNA primer. The codon table was completed by using RNA...

The nature of the genetic code also protects us from mutation. Two or three codons may specify an amino acid and these codons only differ at the third base. If the third base in the codon is replaced, can it result in the same amino acid? If the second base in the codon changes to a different base, it will change to a different amino acid. Amino acid changes can be conservative or non-conservative. If it is a conservative missense...

3. Genetic Information in E. coli DNA The genetic information contained in DNA consists of a linear sequence of coding units, known as codons. Each codon is a specific sequence of three deoxyribonucleotides (three deoxyribonucleotide pairs in double-stranded DNA), and each codon codes for a single amino acid unit in a protein. The molecular weight of an E. coli DNA molecule is about 3.1 3 109 g/mol. The average molecular weight of a nucleotide pair is 660 g/mol, and each...
