B. Deposition
Deposition is the dropping of sediment by wind, water, ice, or gravity.
A forensic scientist must have a minimum of a bachelor’s degree. Although a degree in natural science or forensic science is recommended, some crime scene investigators begin as police officers and lean on their work experience to move into the investigator position. They might hold an associate degree or certificate.
Answer:
True
Explanation:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.
I hope this was helpfull
Answer:
The correct answer is: Gene Therapy.
Explanation:
- Gene therapy can be defined as a broad biomedical and biotechnological technique by which diseases resulting due to the inheritance of mutated or inaccurate gene sequence from the parents or the generation of a sudden mutation in the genome of a person during the course of his life can be prevented.
- RNAi or RNA interference technology is one of the many techniques used to correct various hereditary or gene related disorders.
- In this technique, small oligonucleotides of RNA (Ribonucleic acid) of 22 to 24 nucleotides in length are used to bind to the complementary sequence present in the mRNA (messenger RNA) molecules.This results in the generation of double stranded RNA molecules which functions in two ways:
- They are recognised by RISC or RNA-induced silencing complexes, having endonuclease activity. The RISC complex cleaves and degrades the target mRNA and hence prevents the formation of the target protein.
- The double-stranded RNA molecules stalls the ribosomes and prevent their progression along the mRNA molecules, hence protein synthesis in inhibited.
- This technique is useful in the following ways:
- Cancer often results due to the unregulated activation of the oncogenes which are responsible for promoting uncontrolled growth and division in cells. The use of RNAi can prevent the expression of the onco-proteins which are majorly responsible for causing cancer.
- Alzheimer's disease is often caused due to the accumulation of misfolded amyloid beta and tau proteins in the neurons. The RNAi technology can be used to prevent the formation of the improperly folded proteins.
Answer:
#3
Explanation:
The nucleotide insertion changes the reading frame, causing all kinds of problems. Almost none of the codons will code for the same amino acid.
