Fat (lipid) molecules are made up mostly of long chains of carbon atoms.
For a fat molecule to be considered saturated, the carbon chain must have only single bonds between them.
Schematically, they look like -C-C-C-C- ...
If the carbon chain contains one or more double bonds, such as -C=C-C-C, then the given lipid molecule is unsaturated.
If a lipid molecule (fatty acid) contains exactly one double bond in its chain, and the rest are single bonds, it is then called monosaturated. It is a more healthy food source than saturated fats.
Saturated fat are generally solid at room temperatures. Examples include lard, butter, mostly from animal sources. However, coconut oil (solid at room temperatures as well) is a saturated fat.
This was Ernest Rutherford’s gold foil experiment. He used radioactive alpha particles as a part of the experiment and discovered that there was a densely packed, positively charged nucleus in atoms with electrons that were spread out in spaces between nuclei.
True because Weathering is the process breakdown of materials through physical or chemical actions and Erosion occurs when weathered materials such as soil and rock fragments are carried away by wind, water or ice. Many forces are involved in weathering and erosion, including both natural and man-made causes.This will causes rocks to disintergrate
Answer:
The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.
Explanation:
Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.
The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:
- <em>Adenine</em><em> is complemented with uracil, since in RNA the thymine is substituted by this uracil.
</em>
- <em>Thymine</em><em> is complemented with adenine.
</em>
- <em>Cytosine</em><em> is complemented with guanine.
</em>
- <em>Guanine</em><em> is complemented with cytosine.
</em>
Thus an <u>uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T</u>.
