Veins carry deoxygenated blood from the body to the heart so it can be sent to the lungs, pulmonary veins takes oxygenated blood from the lungs to the heart.
Answer:
b. dNTPs lack a hydroxyl group on the 2' carbon of their ribose sugar.
Explanation:
Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) are the monomers for RNA and DNA respectively. Both are the nucleotides with a pentose sugar, a nitrogenous base, and a phosphate unit. The Ribonucleotides (rNTPs) and deoxyribonucleotides (dNTPs) differ from each other with respect to pentose sugar. The ribonucleotides (rNTPs) have ribose sugar while deoxyribonucleotides (dNTPs) have deoxyribose sugar. The deoxyribose sugar of dNTPs lacks hydroxyl group at 2' carbon which is otherwise present in the ribose sugar.
In the DNA, that is why they are called the building blocks of life.
Answer:
A person with two copies of "t" inherited one from their mother and one from their father
Explanation:
This is because both the father and the mother are carriers of "t" alleles which is a bent thumb. When the parent mate, the father donate one t and the mother too donate one t allele, therefore the person will inherit bent thumb from them.
