<h2>ANSWER:</h2>

It controls the heart rate by producing electrical impulses

<h2>EXPLANATION:</h2>

It controls the heart rate by producing electrical impulses and later transmitting electrical signals through the heart muscle, creating the heart to contract and pump blood everywhere into the body. The heartbeat originates from the S.A. node and expands to the walls of auricles which contract.

SA Node<span> which is also known as the sinus node, is the natural pacemaker of the heart. It controls the heart rate by generating electrical impulses and then sending electrical signals through the heart muscle, causing the heart to contract and pump blood throughout the body. </span>

The SA Node is located in the outer layer of the right atrium of the heart, near the superior vena cava. It is made up of a group of cells (myocytes) positioned on the wall of the right atrium, at the center of the heart and near the entrance of the superior vena cava. These cells contract at a rate of about 70-80 times per minute, which make up the natural heart beat.

A technique used in determining the protein binding region in dna (e.g, binding region of RNA polymerase) is called DNA footprinting

One technique used to determine protein binding regions (eg, RNA polymerase binding regions) of DNA is called DNA footprinting. A DNA footprint shows where a protein binds to a DNA molecule. In this technique, a pure DNA fragment labeled with 32 P at one end is first isolated. A trace amount of DNA endonuclease is then added to the mixture of core protein and radiolabeled DNA. RNA sequencing (RNA-Seq) harnesses the power of high-throughput sequencing methods to gain insight into the cellular transcriptome. Compared to previous Sanger sequencing and microarray-based methods, RNA-Seq offers much broader coverage and resolution of the dynamic nature of the transcriptome.

Genetic codes contain____ (Select all that apply.)
Yuki888 [10]

Answer:

- complex info; detailed instructions

genetic codes contain complex information; detailed instructions

Explanation:

The genetic code is a set of rules by which information encoded in the genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells.

-The genetic code consists of 64 triplets of nucleotides. these triplets are called codons. With three exceptions, each codon and codes for one of the 20 amino acids used in the synthesis of proteins. that produces some redundancy in the code: MuscleTech amino acids being encoded by more than one codon.
