What are the steps of DNA Replication in order?

Biology
1 answer:
slega [8]3 years ago
6 0

Explanation:

1) The enzyme helicase catalyses the unwinding of the two DNA strands by disrupting the hydrogen bonds between complementary base pairs.

2) Single-stranded binding proteins attach to the DNA strands to stabilise them and prevent them from joining back together.

3) The enzyme primase catalyses the addition of a short primer consisting of RNA nulceotides to the DNA strand. This serves as an 'anchor' DNA polymerase to initiate replication.

4) The enzyme DNA polymerase synthesizes a new DNA strand by incorporating DNA nucleotides complementary to the existing strand. DNA polymerase activity only occurs in the 5' ---> 3' direction.

5) The enzyme ligase catalyses the formation of hydrogen bonds between the two new pairs of DNA strands, and seals any breakages in the sugar-phosphate backbone.

What is an example of a stimulus and a response that humans exhibit? Can a similar behavior be seen in any other organisms?
Sedaia [141]
Common examples of this would be if you place your hand in extremely warm or cold water, and an immediate response of pulling out of the water or any fluid, is an example of this extreme response, other responses are what is done in everyday, like being thirsty or hungry etc.

While mRNA strands are being created, a sequence is sometimes miscopied. What is the worst that could happen to a cell should th
kupik [55]

Answer:

The most appropriate answer would be The cell will not make functional proteins from that mRNA strand.

The amino acid sequence of the proteins is derived from the nucleotide sequence of the mRNA (messenger ribonucleotide).

If the sequence of mRNA is miscopied, it will change the sequence of amino acids of the protein.

Consequently, the protein may become non-functional.

Multifidus

What is multifidus?

The transversospinal group of deep back muscles includes the semispinalis, rotatores, multifidus, and other short, triangular muscles. They are shorter than semispinalis but longer than rotatores, and they are the thickest muscles in the transversospinal group. On either side of the vertebral column, from the cervical to the lumbar spine, there is a multifidus. Cervical multifidus, thoracic multifidus, and lumbar multifidus are the three regional subgroups of the group.

The spinal column is extended by the multifidus muscles. They contribute to the lateral flexion of the spine as well as some rotation of the vertebral bodies away from the side of contraction.

Multifidus: a muscle in the fifth and deepest layer of the back that helps to erect and rotate the spine by filling in the groove on either side of the spinous processes of the vertebrae from the sacrum to the skull.

many pathogenic bacteria species are becoming resistant to antibiotics. Explain how such adaptations can develop through the pro
mihalych1998 [28]
There may be some strains of bacteria that are naturally resistant to these antibiotics, or there may be some that mutate to become resistant. This means that as antibiotics are used more and more, those that can be killed using the antibiotics die out, but those that are resistant will remain, and will reproduce. Over time, it will be the resistant species that predominate.
