People have manipulated the genome of horses and ponies in the lab to produce the breeds we know today
Transcription occurs in the nucleus of the cell. RNA polymerase breaks the hydrogen bonds and unzips a portion of DNA. RNA nucleotides match the DNA strand forming mRNA. In mRNA thymine is replaced by uracil. Once mRNA is formed it leaves the nucleus through a nuclear pore into the cytoplasm. The purpose of mRNA is to remove the protein code out of the nucleus without pulling the DNA out. mRNA then needs to find ribosomes in the cytoplasm which can be found on the rough ER. mRNA has read three bases at the same time and these are called codons. Ribosomes read the mRNA code and add the correct amino acid using tRNA. tRNA has an anti-codon on one end which will match a specific codon, and a specific amino acid on the other end. This will make translation happen.
Translation- mRNA attaches to a ribosome and a start codon must be read. tRNA brings the first amino acid which matches the codon on mRNA. The next tRNA molecule moves in and matches with the codon on mRNA while amino acids form a peptide bond. First tRNA detaches itself and mRNA shifts for the next tRNA molecule to come in. Protein grows until a stop codon is reached and then it's ready to finish folding to become functional.
Answer:
Natural selection.
Explanation:
Natural Selection:
Natural selection is the evolution's one of the basic mechanism in which phenotypic variant individuals or organisms survive or reproduce with change in the heritable traits in a population over generations. With the passage of time, this process help the organisms to adapt their environment.
So, the population A and population B organisms interbreed and produce offspring with the process of natural selection.
I don’t think anyone knows the answer to this question, but you should maybe go to a pet shop or something
6. pegmatitic (a pegmatite is a very coarse-grained intrusive igneous )
rock
7. shallow sea (limestone is the most common cemical sed rock, and they are most commonly in shallow marine environments)
8. sunlight (wind, water and ice are the primary mechanisms for the breakdown and transport of rocks and their erosional products)
9. addition of heat and pressure (heat through contact metamorphism with an igneous mass or by compression and deep burial, and pressure through tectonic forces)
10. a different metamorphic rock (this sounds like a trick question. The use of "additional pressure" implies that pressure has already been applied, in which case a metamorphic rock has already formed. Therefore, a "different metamorphic rock" will result)
11. stratification (strata are sedimentary layers)
12. sedimentary (a conglomerate)
13. extrusive (lavas have formed by "extrusion" from a volcanic edifice
14. organic (includes coal and limestone)
15. it will fizz in acid. (marble still is made up of calcium carbonate, which is the chemical which reacts with acid and fizzes)
