DNA strand replication begins with an RNA primer. DNA strand replication begins with an RNA primer. True False

Biology
1 answer:
nikitadnepr [17]3 years ago

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.

Which object would have a larger gravitational force acting upon it
fiasKO [112]

Answer

Hi,

An object with the largest size will have a large gravitational force acting on it. Explanation

The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.

Best wishes!

The ribosome of the bacterium E. coli includes the ribosomal protein L4 (rpl4). The rpl4 gene carries the instructions for makin
Mandarinka [93]

Answer:

Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.

Explanation:

Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.

The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.

Genetic diversity is ultimately/mainly the result of _______________
RUDIKE [14]

Answer:

A. meiosis.

Explanation:

Meiosis is one of the two major types of cell divisions in living organisms. Meiosis is the process by which four daughter cells that are genetically different from the parent cell are produced. Meiotic process is carried out solely during sexual reproduction to yield gametes or sex cells.

The gametes have their chromosomal number reduced by half during the process. However, one immense importance of meiosis is that it PROMOTES GENETIC DIVERSITY. A process called crossing over, which is the exchange of chromosomal segment between non sister chromatids, makes this possible.

What happens if hypothetically all cells in our body becomes cancerous suddenly start to metastasis​
GaryK [48]

Answer:

Explanation:

Cancer is a disease of uncontrolled cellular growth. Your body has many mechanisms in place to prevent a cell from dividing uncontrollably. But when the DNA of a cell is mutated, the proteins that govern cell cycle activity can be changed, and a cell may be able to circumvent the body's mechanisms
