Answer:
Tendon sheaths <u>act as friction-reducing structures.</u>
Explanation:
Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.
The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.

Answer:
During the process of translation, the codon UAC sets up the open reading frame in the mRNA (messenger Ribonucleic acid). The codon UAC corresponds to ATG in the DNA. It codes for the amino acid methionine.
Explanation:
The determination of the open reading frame is important in the process of translation and protein formation. The start and stop codons determine the open reading frame. In DNA (deoxyribonucleic Acid), there are typically six reading frames. The correct frame is determined and the translation is started.
The ATG codon in the DNA sets the reading frame in most of the eukaryotes. Different frames can be started by beginning with either 'A', 'T', or 'G'.
