FANCA is made up of nucleotides.

The insulin receptor is a protein so it is composed of amino acids.

The number of pyrimidines equals the number of purines in a DNA sequence.

There are 7 purines in the DNA sequence below.
5’ A U C G U G A C G U C U A A 3’

5’ G C A T A C T G G A A G C 3’
The sequence above could serve as the genetic material of the pictured organism.

5’ G C A T A C T G G A A G C 3’
The sequence above contains phosphodiester bonds, hydrogen bonds, and peptide bonds.

The oddball is E. coli because it is multicellular, and the others are single-celled.

M. musculus, H. glaber, P. chrysogenum, E. coli

The sequence size is 9 nucleotides.
5’ A T G A C C G A T 3’
3’ T A C T G G C T A 5’

There is a problem with the DNA sequence below.

DNA sequence: 

5’...A C G G A C T A T T T A G C G A 3’

 3’ T G C C T G A T A A A T C G C T... 5’

The coding sequence is always the top strand.

This sequence can be transcribed.
5’ A T G A C C G A T 3’
3’ T A C T G G C T A 5’

Hemoglobin contains nucleotides.

The functional unit of DNA in H. salinarum and P. domesticus is a gene.

H. salinarum has DNA found in a nucleus.

TGA, TAA, ATG, TAG

The oddball out is ATG.

Hemoglobin and rRNA have phosphodiester bonds.

The free NH₂ group would be on the first Met in the protein shown.

The pictured molecule represents a normal DNA sequence.

There is a free sugar on the last purine.

DNA sequence:  5’ T G G G A C T A T T T A G C G C A G 3’

The sequences are labelled correctly.

The top sequence produced the mRNA sequence, 5' A U G A C C G A U 3'.
T A C T G G C T A

A T G A C C G A T

The sequence below contains a stop codon.

Sequence: 5'... A U C U A U C A U A G U U A A U C G 3'

After transcription, the first amino acid coded is TYR.
Template strand:  3’ A T G T C T C A T G A T... 5’
Coding sequence:  5’ …T A C A G A G T A C T A 3’

The following template strand will ultimately produce the protein sequence given below. Note - a start codon is found upstream of the given sequence
Template strand:  3’ ... A A T C A T G A T G... 5’
Protein sequence:  5’ Asn – His –  Asp 3’

There are five codons in the following sequence.

5' A C C G G A U A C G G G C U A U G A 3'

Collectively, the sequence below and its complement contain 34 hydrogen bonds.
Template strand:  3’ T C T C A T G A T 5’
Coding sequence:  5’ A G A G T A C T A 3’
