Answer: A) They are the site of protein synthesis.
Explanation:
Ribosomes are small round organelles attached to the endoplasmic reticulum in cells, and serve as site of protein synthesis. This is possible because the transfer RNA assembles amino acids to form polypeptide chains right in the ribosomes.
Thus, ribosomes are site of protein synthesis
Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.
<h3><u>Explanation:</u></h3>
Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.
Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.
Answer:
DNA is a double helix and has base-pairing between nucleotides through the use of hydrogen bonds
Explanation:
The nucleotides are made up of a nitrogen base [base-pairing adenine (A) with thymine (T) and guanine (G) with cytosine (C)], a phosphate, and a deoxyribose (sugar); all of which are held together by hydrogen bonds. The binding allows the DNA to have a sugar-phosphate backbone connected with hydrogen bonds because they are firm but also easy to break (for DNA transcription)
