Which statement accurately describes how genetic information is transferred during meiosis?

Who took the x-ray photograph that gave the final clue to DNA's true shape

Katyanochek1 [597]

Photo 51, showing x-ray diffraction pattern of DNA
Photograph 51 is the nickname given to an X-ray diffraction image of DNA taken by Raymond Gosling in May 1952, working as a PhD student under the supervision of Rosalind Franklin,[1][2][3][4] at King's College London in Sir John Randall's group. It was critical evidence[5] in identifying the structure of DNA.[6]

You are not posting the statement of the question but, If you are asking about the properties shared by RNA polymerase and the DNA polymerase, the correct ones are:

They both depend on a DNA sequence template.

Catalyzes phosphodiester bond formation.

Proteins may be classified according to their three-dimensional shapes. Determine whether the following examples and description

m_a_m_a [10]

Answer:

-often function as enzymes or transport proteins ⇒ globular proteins

-peptide chains arranged in long strands, or fibers ⇒ fibrous proteins

-peptide chains highly folded into spherical shapes ⇒ globular proteins

-keratins ⇒ fibrous proteins

-hemoglobin ⇒ globular proteins

-water-soluble ⇒ globular proteins

-collagens ⇒ fibrous proteins

-insoluble in water ⇒ fibrous proteins

-generally function in structure and support ⇒ fibrous proteins

Explanation:

<u>Fibrous proteins </u>are composed by large polypeptide chains which interact each other and form large structures. They have water insoluble and have structural and protection functions- they are components of cells and tissues. Examples are: collagen, fibronectin, keratin, elastin, actin.

<u>Globular proteins</u> have a spherical compact structure in which hydrophobic aminoacids are buried inside the structure and hydrophilic aminoacids (which can interact with water molecules) are exposed to the exterior medium. For this, they are water soluble. They have often transport and catalytic functions. For example: hemoglobin, mioglobin, albumin, enzymes in general.

Explain the rock cycle by describing how an igneous rock can become a sedimentary rock, then a metamorphic rock, and then an ign

Paraphin [41]

An igneous rock can be formed from cooled magma. The igneous rock can become sedimentary if it is broken down by wind or water. The sedimentary rock can become metamorphic if it becomes buried in the earth, where pressure and heat would turn it into a metamorphic rock. The metamorphic rock can then become an igneous rock by melting underground and turning into magma, flowing out of a volcano, and cooling.
