Mama L [17]3 years ago

Answer:

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."

Explanation:

The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact.  When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.

Which statement regarding Bax and Bak, two members of the Bcl-2 family, is true?
vampirchik [111]

Answer:

Option D When activated, Bax and Bak form oligomers in the outer membrane of mitochondria, leading to the release of cytochrome c.

Explanation:

The proapoptotic genes are involved in the process of apoptosis. The antiapoptotic gene prevents apoptosis that is cell death. The proapoptotic genes are bax, bak, bad and bid. The bcl family genes are antiapoptotic genes. The process involved activation of apoptosis inside the cell is called intrinsic pathway of apoptosis.

The activation proapoptotic genes, Bax and Bak form oligomers in the mitochondria outer membrane. These pores in the mitochondrial membrane allows the release of cytochrome-c that further attaches with Apaf-1. This leads to activation of caspase 9 that further activates caspase 3, thus inducing apoptosis.

Circle the recombinant DNA constructs below:
Gekata [30.6K]

The correct answer is that a bacteriophage lambda chromosome containing the human collagen gene, because Recombinant DNA is the name given to DNA molecules that have part of DNA derived from two or more sources, usually these sources are different species. Recombinant DNA technology is also known as molecular cloning or even gene cloning.

B. A bacteriophage lambda chromosome containing the human collagen gene

<h3>How is recombinant DNA produced?</h3>

Obtaining recombinant DNA is based on the molecular cloning technique. The process can be summarized as follows:

  1. The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
  2. The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
  3. The bacterial plasmid has the ability to insert a fragment of DNA external to its own genome.

<h3>What is DNA and what is it for?</h3>

DNA is the structure responsible for the transmission of all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. Thus, the main function of DNA is to transport information contained in its sequences, called genes.

Kay [80]

Answer:

A site

Explanation:

During the process of translation, ribosomes play a major role in connecting mRNA codons with tRNA anticodons. Ribosomes are composed of  two subunits which consist ofproteins and rRNA. The tree sites of ribosomes are:

  • P site or peptidyl site-this site binds to the tRNA which holds the growing polypeptide chain.
  • A site or acceptor site-this is a site of peptide bond formation between the growing polypeptide and the next incoming amino acid
  • E site or exit site-the site for the final binding of t-RNA .
