The Myofilaments being used on a muscle contraction would return to their resting state when the sarcomeres would relax. The Sarcomeres are the individual contractile of the myofibrils which are then considered as the tiny rod like elements that are found within the muscle cells.
Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.

Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
Answer:
nuclei, mitochondria or chloroplasts
Explanation:
Bacteria cells are very different from animal, plant or fungal cells. They don't have organelles such as nuclei, mitochondria or chloroplasts. ... Bacteria cells do have a cytoplasm and cell membrane though
