举一反三
- Which of the<br/>following statements about non-coding DNA is wrong? () A: DNA sequence of non-coding protein. B: DNA sequence of non-coding RNA and protein. C: DNA sequence participating in the regulation of gene expression, but<br/>not coding protein. D: Relate to genome protection.
- A cell's _______ is the entire sequence of nucleotides in an organism’s DNA, which provides a genetic program that instructs the cell how to behave.
- The sequence of part of a DNA strand is the following: -ATTCGATTGCCCACGT-. When this strand is used as a template for DNA synthesis, the product will be which one of the following?
- A gene knock-in (or knock-in) refers to a genetic engineering method that involves the one-for-one substitution of DNA sequence information in a genetic locus or the insertion of sequence information not found within the locus. A gene knock-in therefore can be seen as a gain of function mutation and a gene knockout a loss of function mutation, but a gene knock-in may also involve the substitution of a functional gene locus for a mutant phenotype that results in some loss of function.
- Which of the following statements about non-coding DNA is true ()? A: DNA sequences that do not encode proteins B: DNA sequences that do not encode RNA and proteins C: DNA sequence without function D: DNA sequence without phenotype after deletion<br/>[单选题][2分][难度3]
