Circulating plasma antibodies recognize a what as self and thus do not initiate an immune response
rosijanka [135]

The right answer is a surface glycoprotein.

The antigens of the non-self correspond to any substance foreign to the organism, identified as such by the immune system of our organism which produces an energetic defense. Antigens are usually proteins (more specifically glycoproteins) contained in cells or foreign bodies (red blood cells transfused, organs transplanted, bacteria, viruses), or present in the environment (pollen, mite droppings, cat hair , etc.).

Our body has its own antigens that allow it to have a "specific identity card" and will be recognized as foreign by other organizations. They are called "self antigens".

Nirenberg and leder used synthetic ‘triplets’ of rna. The purpose of these short rna molecules was to.
dmitriy555 [2]

Take the place of part of an mRNA within the ribosome.

Rna triplets

The nucleotide sequence copy of a gene is present in the mRNA. Each amino acid is represented by a triplet of the four nucleotide bases that make up the genetic alphabet. The relationship between triplet sequences and amino acids is known as the genetic code.

A codon is a triplet of RNA nucleotides that codes for a particular amino acid. To the ribosome, where translation takes place, the tRNA transports certain amino acids. During translation, the anticodons in the tRNA bind to the codons in the mRNA templates. It is essential for the codon and anticodon to interact in order to pair the codon with the appropriate amino acid.

In mRNA, each trio of nucleotides is referred to as a codon, and each codon designates a certain amino acid (hence, it is a triplet code).

Answer in a paragraph
san4es73 [151]

Answer: <em>Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:</em>

<em> </em>

<em>1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up </em>

<em>2. Metaphase: Chromosomes line up at the centre of the cell. </em>

<em>3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells. </em>

<em>4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.</em>

What is needed in order to give the DNA polymerase a place to start copying DNA? How long is it? What puts it on?
zzz [600]

DNA polymerases add nucleotides to the 3′ end of a polynucleotide chain. ... To initiate this reaction, DNA polymerases require a primer with a free 3′-hydroxyl group already base-paired to the template. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.

How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
