A constant is something that is kept the same throughout the course of a experiment. So I would guess C) because they are not doing anything special. If it’s not C then it is A. :)
Nucleosomes are composed of "histones" class of molecules.
<u>Explanation:</u>
Histones usually presented in eukaryotic nuclei of cells which seemed as strong level of proteins that bundle and organize DNA into structural groups called nucleosomes in biological science.
They are chromatin's chief protein elements, functioning as spools along which DNA spins, and playing a major role in regulating genes. Five forms of histones have been recognized:
- H1 (or H5), H2A, H2B, H3, and H4;
- H2A, H2B, H3, and H4 are the main histones and H1 and H5 are the linker histones.
Answer:
Orbital
Explanation:
I believe, to the best of my knowledge, that the answer that you're looking for here is the Orbital. Hopefully this helps.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed question can be found in the attachment below.
During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow
DNA: T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A
mRNA: A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U
Amino Acids: met -- leu -- met -- lys -- lys -- Glu -- Phe
The new amino acid sequence is represented above from the new DNA sequence.
Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
