Answer #1

Option 1. Many genes in the cells are being actively transcribed.

Euchromatin is the lightly packed form of chromatin which is rich in genes that are actively transcribed. Heterochromatin is the tightly wound form of chromatin which is rich in genes that have to be kept in repressed state.

    Question 18 Which of the following statements is FALSE? Euchromatin is replicated throughout the S phase while heterochromatin is replicated late in the Sphase. Euchromatin is found in the arms of chromosomes while heterochromatin is found at the centromeres, telomeres, and other specific locations Euchromatin has higher numbers of genes than heterochromatin. Euchromatin has fewer crossovers than heterochromatin. Euchromatin has fewer repetitive sequences than heterochromatin.

    The MyoD transcriptional regulator is normally found in differentiating muscle cells and participates in the transcription of genes that produse fic proteins, such as those needed in contractile tissue. Amazingly. expression of MyoD in fibroblasts causes these cells n connective tissue to produce proteins normally only seen in muscles. However, some other cell types do not transcribe muscle-specific genes when MyoD is expressed in them. Which of the following statements below is the best explanation of why MyoD can cause...

    Which of the following is a correct about how lymphocytes in the Adaptive Immune System acquire millions of possible combinations of antibodies? Vertebrate genomes have millions of different antibody genes, which are constantly being transcribed and translated. After differentiation, a small number of immunoglobin genes in each lymphocyte undergo internal recombination to create a unique antibody for each B-cell or T-cell. RNA interference cleaves viral nucleotide sequences, then uses them as a template to produce special antibodies that can target...
