Answer: The mRNA sequence is CGUAGGCU

The sequence of DNA molecule is GCATCCGA and when it is transcribed, it forms mRNA ( messenger RNA). The mRNA sequence is complementary to the DNA template. The corresponding nucleotides in mRNA are added in the following manner-

For G in the DNA, C ( cytosine) is added in mRNA and vice versa. Similarly, for A ( adenine) , U ( Uracil) is added in mRNA and for T( thymine), A ( adenine) is added in mRNA.

Thus, for the given DNA sequence, CGUAGGCU is the right mRNA sequence.

What can be inferred about a petrified log? the wood needed long ages before it could petrify the tree laid on the surface for l
RideAnS [48]

Answer:

the petrified log looks like the original tree.

Explanation:

A tree to be petrified first needs to be buried. An element laying on the surface can not be petrified because it is exposed to many different factors (such as<em> organisms, microorganisms, climatic conditions</em>, etc.), that affect the petrification process. So, in the case of a fallen tree, first, it needs to be covered by many sedimentary layers. Once it is underground, it also needs the presence of underground water and minerals. Water replaces the original organic material with minerals (silica, calcite, and pyrite). This replacement process results in the conversion of the woody material into a fossil of the original material. Very often, the tree details are so preserved that the fossil looks exactly like the original trunk.

Depending on the preservation degree, a fossil can be useful for different studies about the past.

Which statement is not true? A) Lipids are found in cell membranes. B) Lipids are soluble in organic solvents. C) There are many
alina1380 [7]

Answer:

D.all lipids contain fatty acids.

Explanation:

A.Lipids are fats, like oil, that are insoluble in water. ... The most abundant class of lipid molecule found in cell membranes is the phospholipid. The phospholipid molecule's polar head group contains a phosphate group. It also sports two nonpolar fatty acid chain groups as its tail.

B.The simplest definition is a lipid as any molecule that is insoluble in water and soluble in organic solvents. Most lipids are soluble to some extent in organic solvents such as hexane, ether, chloroform or benzene. They constitute a complex collection organic compounds that include fatty acids, (A,D, E and K).

C.There are two major types of lipids- simple lipids and complex lipids. Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes.

D.Not all lipids have fatty acids. The operational definition of a lipid is a biomolecule is that is sufficiently hydrophobic to be more soluble in an organic solvent than in water. The common theme to their structures is a high percentage of hydrocarbon character.

E.Most lipid hormones are steroid hormones, which are usually ketones or alcohols and are insoluble in water. Steroid hormones (ending in '-ol' or '-one') include estradiol, testosterone, aldosterone, and cortisol. ... Amino acid-derived hormones and protein hormones are water-soluble and insoluble in lipids.
