Sailors had scurvy, which is caused by a lack of vitamin C. They were cured by lemon juice becaue it contains a lot of vitamin C. Vitamin C evaporates when the lemon juice is boiled so it wouldn't have the same effect.
Answer:
a. can produce many exact copies of segments of DNA
Explanation:
PCR refers to polymerase chain reaction that replicates a gene or a DNA segment into multiple copies. For the purpose, primers, the sample DNA template to be amplified, nucleotide monomers and the heat-tolerant DNA polymerase enzyme (<em>Taq </em>polymerase) are mixed.
The heating of the mixture leads to the denaturation of the sample DNA. The mixture is cooled down to allow annealing of the primers to the DNA template which is then amplified by the enzyme <em>Taq</em> DNA polymerase. The reaction mixture is heated to allow denaturation of all the DNA molecules which in turn serve as a template and the process is repeated for several rounds according to the requirement of the copies of the sample DNA.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities
Explanation:
Answer:
The phenotype would be brown eyes.
Explanation:
Dominant alleles always show up above recessive alleles. since brown is dominant brown will show.
Answer:
The TATA box Is a sequence in DNA that provides a site for transcription factors to bind to.
The TATA box Is also known as a promoter.
Explanation:
The TATA box is not a sequence in RNA that signals that a protein should be synthesized on the rough ER.
The TATA box Is not a sequence in RNA that signals the formation of ribosomal subunits
TATA Is not a sequence in DNA that provides a site for helicase to unwind DNA.
