Answer to Problem 1MC
Solution:
Description | Key |
Exhibit a joint cavity | Synovial joint |
Types are sutures and syndesmoses | Fibrous joint |
Bones are connected by collagen fibers | Fibrous joint |
Types include synchondroses and symphyses | Cartilaginous joints |
All are diarthrotic | Synovial joint |
Many are amphiarthrotic | Cartilaginous joints |
Bones are connected by a disc of hyaline cartilage or fibrocartilage | Cartilaginous joints |
Nearly all are synarthrotic | Fibrous joint |
Shoulder, hip, jaw, and elbow joints | Synovial joint |
Explanation of Solution
A synovial joint consists of a cavity. It is made up of dense and irregular connective tissue and forms the articular capsule. The capsule is linked with the accessory ligaments. The ends of the joint bones are surrounded by a smooth glass-like hyaline cartilage.
The fibrous joints are sutures, gomophoses, and syndesmoses. Suture is narrow and joins most of the bones of the skull together. Syndesmosis is a slightly movable joint where bones are joined together by a connective tissue.
The fibrous joints are attached to each other by a connective tissue. This tissue consists of collagen fibers. The fibrous joint has three types, namely, suture, gomphosis, and syndesmoses.
The cartilaginous joints are attached to each other by a cartilage. It allows more movement between two bones as compared to the fibrous joint. The primary cartilaginous joints are known as synchondroses and the secondary cartilaginous joint is symphysis.
The synovial joint is known to be diarthrotic. It joins with the fibrous joint capsule that is continuous with the periosteum of the fixed bones. It consists of an outer boundary of synovial cavity.
Amphiarthrosis is a kind of continuous and slightly movable joint. The contiguous bony surface can be symphysis that is connected by broadly flattened discs and an interosseous membrane. It is seen in cartilaginous joints.
The cartilaginous joint involves the fibrocartilage or the hyaline cartilage. The joints are slightly movable, that is, they are amphiarthrotic. They are connected by cartilage and allow the movement of bones.
The fibrous joints can be synarthrotic or amphiarthrotic. The sutures are synarthrotic joints and are situated between the bones of the skull. The edges of the bones are interlocked and they are bound together at suture.
The hip, shoulder, and jaw consist of a synovial joint. A synovial joint consists of a cavity. It is made up of dense and irregular connective tissue and forms the articular capsule.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA?

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
