Answer:
The correct answer is DNA ligase.
Explanation:
DNA Ligase is an enzyme with links 2 strands of DNA by creating a bond between the phosphate group of 1 strand and deoxyribose group of the other strand of DNA.
In cells, it is used to join the Okazaki fragments together which are formed on the lagging strand during the process of DNA replication.
Okazaki fragments are tiny pieces of DNA nucleotide which are formed in a discontinued manner but latter they are joined by DNA ligase enzyme.
Answer:
3.45g/cm³
Explanation:
The density of a substance/object can be calculated by using the formula:
Density = mass/volume
Where;
Density = g/cm³
Mass = grams
Volume = cm³
According to this question, a student measured the mass and volume of an object using a triple beam balance and a graduated cylinder. The sample has a mass of 22.4 grams and a volume of 6.5cm³.
Hence, the density of the object can be calculated this;
Density = mass/volume
Density = 22.4/6.5
Density = 3.4461
To the nearest hundredth, the density of the object = 3.45g/cm³
