Which biomolecule determines a person's ability to clot blood properly?

Biology

Answer:

D- Nucleic Acids

Explanation:

Blood clotting is a process whereby a person's blood coagulates due to the formation of a white fibrous protein substance called FIBRIN. The essence of blood clotting is to prevent excessive flow/waste of blood when a blood vessel is wounded.

However, certain substances are needed for this process of blood clotting to occur in our body. Some individuals lack this substances and hence bleed continuously during injury, a condition known as HEMORRHAGE. The substances such as FIBRIN, a protein needed for blood clotting is encoded by GENES which makes up DNA (a type of nucleic acid).

Therefore, NUCLEIC ACID biomolecules determines a person's ability to clot blood properly because nucleic acids make up DNA, which contains segments (genes) that encode the synthesis of proteins (fibrin) needed for blood clotting to occur. Hence, it all boils down to NUCLEIC ACIDS.

A gene includes the sequence AGAACT. When it is transcribed, what will the RNA sequence be? A. UCUUGA B. UGCCGU C. UCUUTC D. TCT
Margaret [11]

Answer:

A

Explanation:

The correct option would be A.

<em>According to the base-pairing rule, Adenine (A) always pairs with Thymine (T) (or Uracil in the case of RNA) while Guanine (G) always pairs with Cytosine (C).</em>

Hence;

             A-U

            G-C

            A-U

            A-U

            C-G

            T-A

Therefore, AGAACT would be transcribed to UCUUGA.
