Answer:
Diarthroses are freely movable joints.
Explanation:
Rheumatology may be defined as the branch of medicine that mainly deals with therapy and diagnosis of the rheumatic disease. The individual specialized in this field is known as rheumatologist.
Diarthroses joint is also known as synovial joint and lined in continuous with the periosteum of the joined bones. The synovial fluid is filled in the synovial joint. The synovial joints provide the free movable joints that allow abduction, extension and adduction of the body parts.
Thus, the correct answer is option (d).
<span>During protein synthesis, the peptide bond between amino acids is formed by the process of condensation. Condensation is a reaction when two smaller molecules (in this case amino acids) make a larger molecule(protein) and water as a side product.</span>
Answer:
- Restriction enzymes break a phosphodiester bond on both of the DNA strands.
- Two different linear DNA molecules are cut with a single restriction enzyme such that only one end of each molecule is cut and these ends have regions of single stranded DNA. The two different DNA molecules will have compatible ends.
Explanation:
Restriction enzymes are a type of enzyme that recognizes target DNA sequences and cuts them at these specific sites. These enzymes catalyze the hydrolysis of phosphodiester bonds by cleaving double-stranded DNA (dsDNA) sequences at specific sites on both DNA strands. There are restriction enzymes that generate sticky ends (cohesive ends), i.e., small stretches of single-stranded DNA (ssDNA) that self-ligate or ligate with a complementary region from another DNA molecule. Restriction enzymes that generate sticky ends are very useful in molecular cloning and DNA recombination techniques because they can hold two pieces of DNA together so that DNA ligase can covalently link them.
A chromosome is made up two chromatids that are joined in the centromere. Chromatids will separate during mitosis to create brand new chromosomes.
