The study of cells is called cell biology. There are two types of a cell on the basis of their number and these are unicellular and multicellular.
The correct answer to the question is option C that is insertion mutations can affect many amino acids in the protein.
The formation of protein is called translation. This addition of genes changes the sequence of RNA which alters the protein formation while in point mutation it changes only one amino acid.
Hence, the correct answer is option C.

Answer:
An Experiment to get proof that the two genes are equivalent functionally will be to introduce the aneroid mutation from the human eye with the condition into the embryos of Drosophila (small fruit flies) and look out for the formation of iris.
Explanation:
There exists a medical test called The Invitae Aniridia Test which can analyze the primary gene associated with aniridia however, in order to provide evidence that these same gene is also present in small fruit flies (a genus of flies called Drosophila) The method described in the answer above will do.
Answer: Food
Explanation: Of course, animals need food in order to gain mass. The food is used to transfer into cells, forming tissues, skin, and muscle to the animal.
Hope this helped!
Explanation:
Mainly by submerged fermentation using Aspergillus niger or Candida sp from different sources of carbohydrates, such as molasses and starch based.
Answer: b. the height of the plant.
In an experimental set up an independent variable is the one which can be manipulated or change to observe the effects of such changes or manipulation on dependent variable. For example, plant growth is a dependent variable because it is dependent on independent variables such as amount of sunlight available, amount of fertilizers and water provided.
In this experiment, it is to be determined that how the amount of water given to a plant affects its growth. Here, water is an independent variable which can be change in the experiment and the affect of change can be observed on plant growth which is a dependent variable. A height represents the growth of the plant therefore, height of the plant is the dependent variable.
Answer:
The amount of carbon-dioxide atoms released by respiration are exactly equal to the atoms of these materials contained in the oxygen and carbon converted.
Explanation:
B. The two-dimensional structure of tRNAs exhibits a cloverleaf pattern.
C. tRNAs are produced in the nucleus.
D. functional tRNAs have been spliced by splicesomes.
E. tRNAs possess an anticodon complementary to the codon.
Answer:
D. functional tRNAs have been spliced by splicesomes.
Explanation:
Functional tRNAs are not spliced by splicesomes, they are trimmed with the help of RNAases instead.
In all tRNAs, RNAase P cuts at 5'end so as to produce a monophosphate because a phosphodiester bond consists of only one phosphate and 2 sugar molecules.
After that 3'end processing occurs in which RNAase II and RNAase D remove extra nucleotide sequences at 3' end. CCA is added at 3' end later on with the help of enzyme named as tRNA nucleotidyltransferase.
So, there is no role of splicesomes only RNAases and other enzymes are involved in tRNA processing.
The false statement about tRNA is that functional tRNAs have been spliced by spliceosomes. tRNA processing involves cleavage and modification, but not with spliceosomes, and this occurs before tRNAs are active in the cytoplasm for protein synthesis. So the correct option is D.
The correct answer to the question "Which of the following statements about tRNA is FALSE?" is D. Functional tRNAs have been spliced by spliceosomes. This statement is false because tRNA processing does not involve spliceosomes, which are specific to mRNA splicing. It is essential to note that, unlike mRNA, tRNA and rRNA are not translated but are involved in protein synthesis in other roles. In eukaryotes, tRNAs are transcribed and processed in the nucleus, but they undergo further processing that includes splicing, methylation, and sometimes nucleotide modification but not by spliceosomes. Following the processing, tRNAs are then exported to the cytoplasm.
tRNA molecules are typically depicted in a two-dimensional cloverleaf pattern, but in three dimensions, they adopt an L-like shape. The molecule is folded due to intramolecular base pairing, creating a structure with an anticodon at one end and an amino acid binding site at the other. Importantly, the anticodon of a tRNA is complementary to the mRNA codon, enabling the tRNA to bring the correct amino acid to the growing polypeptide chain during protein synthesis.
