Answer is Communicable disease can be spread by inanimate objects, such as doorknobs.

The causal organisms of some of the communicable diseases are bacteria and viruses. The communicable diseases such as common cough and cold can be transmitted to a healthy person by indirect contact with contaminated substances such as food, air, soil, feces, equipment, objects including doorknobs, remote controller, etc.

Which joint performs adduction, abduction, horizontal adduction and abduction, medial and lateral rotation, and circumduction?
VLD [36.1K]

Answer:

The ball and socket joint is the one that can perform all those movements.

Explanation:

Ball and socket joint, also know as spheroid joint are types of joints where the part of the bone that articulates with the other bone has a spheroidal shape or ball shape that fits in the depression of the other bone, which means that they are a synovial enarthrosis joint. It has a wide range of movements because it can move in the transverse, vertical, and sagittal axes. An example of this joint is the shoulder, between the scapula and the humerus.

If one strand of a DNA molecule has the sequence of bases 5′-ATTGCA-3′, the mRNA synthesized following the template will be ____
rjkz [21]

If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.

Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing  template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.

The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.
