Difference between primary and secondary sequence database?

Primary sequence databases store experimentally determined sequences, while secondary databases compile and organize information from primary databases along with additional annotations, classifications, and analyses.

Complementary dna sequence?

A complimentary DNA sequence is the genetic code on the partner strand that aligns with and corresponds to (matches) the code on the primary strand. Each nucleotide has a match, A matches T and C matches G, therefore the complimentary sequence for ATCGA is TAGCT.

The sequence of amino acids joined together refers to the?

Peptide sequence or amino acid sequence is the order in which amino acid residues, connected by peptide bonds, lie in the chain in peptides and proteins. The sequence is generally reported from the N-terminal end containing free amino group to the C-terminal end containing free carboxyl group. Peptide sequence is often called protein sequence if it represents the primary structure of a protein.
