ANSWER
mRNA - formed from the DNA gene sequence with the help of RNA polymerase.
EXPLANATION
mRNA contain codons which are complement to
tRNA anticodons.
rRNA formed in nucleolus.
tRNA carries the amino acid.
The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
The Prostate gland
The prostate is a walnut-sized organ that surrounds the
first part of the urethra. It is located between the bladder and the penis. Semen
is formed by the prostate by combining a thick white fluid it initially produced
with the sperm from the testicles. It also produces an antibiotic protein known
as prostate-specific antigen (PSA) that changes the semen into liquid.
