BLAST (Basic Local Alignment Search Tool) is a powerful tool for comparing unknown sequences to sequences in online databases. I
storchak [24]

Answer:

This is a well conserved sequence.

Explanation: BLAST a way to match or align a string of DNA or protein sequence to those that are already in a database. The way that this is done is by using statistics carefully to calculate the significance of the match. The BLAST result will produce 4 categories Max Score, Total Score, Query cover, E-Value Percent Identity. The Accession will indicate database of the sequence. In this Sequence: AAGACCCGCCGGGAGGCAGAGGACCTGCAGGGTGAGCCAACCGCCCATTGCT covers over 98.08% identity to the coding sequence (cds) of insulin. This sequence appears to be in a conserved region for many of the listed organism. This suggest that this part of the coding sequence for this protein is highly conserved

What are the three types of cell signaling
PIT_PIT [208]

Answer:

there are 4: paracrine signaling, autocrine signaling, endocrine signaling, and synaptic signaling

Explanation:

paracrine:cells that are near one another communicate through the release of chemical messengers 

autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface 

endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send. 

synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.

What does reverse transcriptase use to form dna apex?
Marianna [84]

Reverse transcriptase use mRNA to form DNA apex

Reverse transcriptase is a broad family of enzymes that play a unique role in the flow of genetic information. The synthesis of DNA from an RNA template through reverse transcription produces complementary DNA. Reverse transcriptase use an RNA template and a short primer complementary to the 3' end of the RNA to direct the synthesis of the first strand complementary DNA, which can be used directly as a template for the Polymerase Chain Reaction.
