When does DNA polymerase check for mutations?

Biology
1 answer:
marta [7]3 years ago
3 0

Answer:

during DNA replication

Explanation:

During DNA synthesis, when an incorrect nucleotide gets inserted in daughter strand of DNA, DNA polymerase goes back by one nucleotide pair, excises the mismatched nucleotide and repairs error. Thus, the DNA polymerase checks for mutations at the time of DNA replication

​(f) contact a local hospital and ask them the percentage of the population that is blood type o. why might the results​ differ?
Fudgin [204]
Contacting a local hospital and asking them the percentage of the population that has blood type O will generate different results. 

The factors that we have to consider why there is differing results are:
1) location of the hospital
2) nationality of their patients
3) number of their patients

I am assuming that the population that question is referring to is the number of patients in the local hospital. The bigger the population, the smaller the effect a unit has on the whole and vice versa. 

I read an article that states that 37% of the U.S. population has O+ blood type. These people are usually of Hispanic descent or some Asian descent. So, if a hospital is in a locality that has a majority of Hispanic or Asian patients, its percentage will be higher than a hospital that is located in a Caucasian-populated area. 

Aside from Type O+ (most common), blood types also include: O-, A+, A-, B+, B-, AB+, and AB- (rarest blood type)

Which of the following is not a part of the process of translation?a. initiator tRNA binding to the ribosome b. removal of intro
inna [77]

Answer: b. removal of introns from mRNA

The process by which Ribosomes   attached to ER or lying freely in the Cytoplasm  synthesize  proteins from the transcribed mRNA of  the DNA is called Translation.

Explanation:

It is made up of three stages;

1. INITIATION;Options C   mRNA binding to the ribosome

2. ELONGATION ;Option D joining large and small ribosomal subunits

3, TERMINATION;Option E chain termination at a stop codon

However, Introns are non coding  region  of RNA base sequence  transcribed from the DNA, or  sections  of DNA encoding  the RNA. It is  an unwanted part which must be sliced out  before translation. Therefore it is not a relevant  steps of translation, and  hence   Option B is  the wrong answer.

Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.

vredina [299]

Answer: Aerobic respiration will not take place and the animal will lose large amounts of ATP.

Explanation:

Mitochondria is the powerhouse that converts product of glycolysis that occurs in the cytoplasm into energy and release carbon dioxide as a byproduct. In the presence of oxygen (aerobic), products of glycolysis such as pyruvate enters the mitochondria, joins the kreb cycle and the electron transport chain yielding a large amount of energy or ATP.

Aerobic respiration that yield large amounts of ATP strictly occus in the mitochondrial matrix whereas anearobic respiration occurs in the cytoplasm.
