Humans are able to move their shoulder 360 degrees. What morphological features aid in this degree of motion (i.e. which bones)?
Svetlanka [38]

Answer:

This question is incomplete because of the absence of bat diagram discussed in the question

Explanation:

Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.

<u>The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement</u>.

Which of the following correctly describes the process of Translation?
Lyrx [107]

Answer:

I. tRNA anticodon bonds to mRNA codon

II. Ribosome bonds to mRNA strand

III. Ribosome reaches a STOP codon and detaches from the mRNA

IV. Each tRNA adds an Amino Acid to the chain as the Ribosome moves along the mRNA

Explanation:

Translation is the second process of gene expression in which a protein molecule is synthesized from the information in a mRNA strand. Translation occurs in the RIBOSOME (an organnelle for protein synthesis made up of ribosomal RNA (rRNA) and proteins). The process of translation occurs in three stages viz: Initiation, Elongation and Termination.

Initiation occurs when the ribosome binds to the mRNA strand in the cytoplasm. The mRNA sequence is then read in a group of three nucleotides called CODON by the ANTICODON of a transfer RNA (tRNA). The basis of reading is the complementary base pairing rule i.e. A-U, G-C. Options I and II describes this stage.

In the elongation stage, the tRNA carries an amino acid corresponding to what it reads in the mRNA codon to the growing polypeptide chain. The amino acids bonds to one another via a peptide bond. As each codon is being read, the mRNA gradually moves over the means sequence. Option IV describes this stage.

Elongation stage continues until any of the stop codons (UAA, UAG, and UGA) are finally encountered by the trans in the ribosome. Since, there are no corresponding anticodons that can read the stop codons, they signal the termination of the translation process. The ribosome then detaches from the mRNA sequence. Option III describes this stage.

Note, option V describes TRANSCRIPTION not TRANSLATION.
