Question

Question 5: Use accession number “CU329670” to search the Nucleotide database.
a. What is the type of sequence? What is the length of sequence? What is the name of database division?
b. What is the scientific name of organism?
Go to the FEATURES section of the record. Link to the CDS to gain access to the first 5662 nucleotides of the sequence.
c. Name the protein product of the CDS and the length of protein.
d. Write the first four amino acids.
e. Write the nucleotide sequence of the coding strand that corresponds to these amino acids.
f. Write the nucleotide sequence of the template strand that corresponds to these amino acids. (Note that the definition of the coding strand is the strand of DNA within the gene that is identical to the transcript and the template strand is the strand that is complementary to the coding strand.)

Answer 1

a. The type of a sequence is DNA sequence.The length of the sequence is 5579133bp. The name of the database is ncbi (Genbank).

b. The scientific name iof organism is Schizosaccharomyces pomb.

c. Protein product is RecQ type DNA helicase.It contains 1887 amino acids

d. The first four amino acids are methionine M ,valine V,valine V, alanine A.

e. 5'ATGGTCGTCGCT3' coding strand

f. 3'TACCAGCAGCGA5' template strand
