siRNA prevent gene expression by binding to the product of transcription because <u>they bind to mRNA</u>
Explanation:
siRNA are short-sequence RNA strands, about 20 bp long, that bind to complementary regions on transcribed mRNA. This causes the formation of regions of dsRNA on the mRNA. This subsequently result in recruitment of enzymes such as Diver enzyme to cleave the mRNA and hence rendering it ineffective for translation into proteins. This is how siRNA negatively regulate genes, a process that has also been identified in research as a window to remedy genetic diseases.

Separation of sister chromatids (D)
Answer:
i can only define the terms for you.
Explanation:
chromosome - a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
chromatid - each of the two threadlike strands into which a chromosome divides longitudinally during cell division, each containing a double helix of DNA.
gene - a distinct sequence of nucleotides that forms a part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell or virus that may synthesize
Answer:
All of the above.
Explanation:
Garden peas were used by Mendel for experiment and are good choice of studying heredity because they have the ability to control their fertilization and transfer pollen . They can engage in either self fertilization or cross's fertilization.
Garden peas are easy to grow and they can be bred very easily and they have alot of traits that can easily be observed i.e their characteristics are visible and they produce many offsprings.
They are of different varieties.
Answer:
data
Explanation:
Experimental data are collected during an experiment in order to measure the dependent variable that is being tested
