Answer:
C
Explanation:
The damage to DNA usually occurs where there are two consecutive thymine nucleotides on a DNA strand. The energy from the UV light causes the two dimers to form a cyclobutane pyrimidine structure. Proofreading and repair mechanism of DNA find it difficult to repair this kind of damage on DNA. During replication, therefore, DNA polymerase is unable to replicate this region hence leading to a mutation on the replicated strand at this local point.
Answer:
Microbial control agents can be described as agents which will inhibit or prevent the growth of microbes. Hence, they will prevent the damages caused by microbes.
Microbial control agents can either inhibit the growth of microbes. In this way, the population of the microbes will not expand and hence, the effect of the microbe on a host will be controlled.
Other microbial control agents kill the microbes and hence, control the effect of microbes.
Answer:
Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.
Explanation:
Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.
Answer:
Antigens on red blood cells are hereditary traits that allow blood to be typed in different ways. One system is based on a gene with two alleles, M and N. If the frequency of the M allele in a population is 0.4, then according to the Hardy-Weinberg rule, the expected frequency of the heterozygous MN genotype is 0.48.
