Answer:
true
Explanation:
DNA synthesis is performed by the enzyme DNA polymerase. However, DNA polymerase requires the presence of a free 3' OH on the existing DNA or RNA segment. The enzyme primase forms small RNA segments that serve as primers. Primers are formed by using the DNA template strands and have free 3' OH ends. DNA polymerase extends the primers by adding deoxyribonucleotides according to the sequence of the DNA template strand. Therefore, DNA polymerases are the enzymes of primer elongation.
Answer:
False
Explanation:
In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.
There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.
Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
Answer:
D. A phosphate group is removed.
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate

Hey there!
1.The metric system is a decimal system of measurement whose units are based on certain physical standards and are scaled on multiples of 10.Metric units of length are easy to use because they are based on multiples of 10.
2.You can immerse the solid in water and measure the volume of the water displaced. The solid cannot dissolve in water.
3.A degree on the Fahrenheit scale must be smaller because there are 180 degrees between freezing and boiling as compared to 100 degrees for the same range on the Celsius scale.
Hope this helped @ShaggySnaps
