Answer:
A meteorite?
Explanation:
It was small and hot because friction from falling to Earth burned it up.

Answer: The frequency of brown beetles is 0.32.
Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:
1 - 0.8 = 0.2
In Hardy-Weinberg principle,
2pq represents the frequency of heterozygote individuals, so:
genotype A1A2 = 2*0.8*0.2 = 0.32.
Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
Answer:
Explanation:
Translation can be defined as the synthesis of polypeptide chains (protein) from mRNA in the ribosome.
For the initiation steps in translation in prokaryotes
The small ribosomal subunit first binds to mRNA.
For the elongation process
It involves the movement of the tRNAs from the sites ( P, A and E) till they leave the ribosome - translocation of ribosome binding of second aminoacyl trna.
Answer:
it is expected to observe two bands: one band of light density and one band of heavy density
Explanation:
DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
