Answer:

Uracil

Explanation:

Transcription is the first stage of gene expression in a living cell and it involves the synthesis of a mRNA molecule using a DNA template. The process of transcription is carried out by an enzyme called RNA polymerase, which initially binds to the PROMOTER region of a DNA, unwind its double-helix and begins to add nucleotide bases to the growing RNA strand based on the nucleotides it reads on the DNA.

The basis of nucleotide addition by RNA polymerase is COMPLEMENTARY BASE PAIRING RULE, which states that Adenine (A) always pairs with Thymine (T) and Guanine (G) with Cytosine (C). RNA polymerase adds to the RNA strand, nucleotides complementary to the ones it reads on the DNA. Since, Uracil base replaced Thymine in the RNA molecule, RNA polymerase adds Uracil to the RNA strand, for every Adenine it reads on the DNA template.

bagirrra123 [75]

Answer:

basically every living thing breathes oxygen O2 and exhales carbon dioxide CO2

Explanation:

So orcas use O2 and produce then CO2.

DaniilM [7]

Answer:

Intermediate Product Accumulation

Explanation:

If one of the crucial enzyme say B is mutated in the process of normal product formation, then the reaction will not proceed further from that point and accumulation of an intermediate product in the cell takes place. The mutation in the enzyme could be environmental or genetic but it will surely alter the enzyme functioning. In the end, the damage malfunctioning cell will be removed using the process of apoptosis.

A bacterial infection of the periodontium that causes rapid attatchment loss and poor response to periodontal therapy has a grade of Aggressive periodontal disease

<h3>Periodontium </h3>

The cementum, gingiva, periodontal ligament (PDL), and alveolar bone make up the complex structure known as the periodontium. The periodontium's main purposes are to protect the underlying structures of the tooth from the oral microflora and to enable the tooth to connect to the bone.

An orthokeratinized or parakeratinized stratified squamous epithelium makes up the gingival epithelium. The gingiva, which has connective tissue and epithelial components, covers the supracrestal root surface and the alveolar bone. As it lines the gingival sulcus close to the tooth surface (enamel or cementum) and subsequently joins to it with hemidesmosomes, the gingival (oral) epithelium develops into the sulcular epithelium and junctional epithelium.
