Answer:
This scientist has likely discovered a <u>protein</u>.
Explanation:
Proteins are complex molecules composed of monomers known as amino acids. They usually have complex structures that makes them fold. Proteins have several functions but they are essential for body functions because they act as biological catalysts in which they speed up chemical reactions.
Answer: The correct answer is -
The new DNA molecule consists of one new strand and one old strand of DNA.
DNA replication is a process of formation of two molecules of DNA from a single DNA molecule (which is double stranded).
In this process, the two DNA strands of the original DNA are first separated so that the template strands are exposed.
Using the template strands, enzyme DNA polymerase adds nucleotides (in the direction 5' to 3') in a complementary manner-
For adenine, thymine, guanine, and cytosine in the template strand, thymine adenine, cytosine, and guanine are added respectively.
The new DNA molecule consists of one new strand and one old strand of DNA. That is why, it is also called semiconservative replication.
Thus, option third is the right answer.
The cell grows, makes a copy of its DNA, and prepares to divide into 2 cells.
Or for APEX---->The chromosomes are duplicated or the cells prepare for mitosis
The cell prepares for mitosis.
Organelles are manufactured(apex)
The statement above is TRUE.
Viral and bacteria STIs are usually acquired through sexual contact with an infected person. These infections have serious devastating effects on the affected and death usually result if the infection is not treated promptly. Some of these infections are still without drugs that can cure them, especially the viral STIS.
Ectoparasitic infections are those infections that are caused by tiny parasitic organisms. They are usually transmitted by close physical contact. The parasite usually affect skin or hair and typically cause itching. The effects of these infections are mild compare to that of viral and bacterial STIs.
A movement in response to gravity is called tropism.
