Question

What is the difference between reproductive cloning and therapeutic cloning?

Group of answer choices

Therapeutic cloning supplies cells for repair of diseased or injured organs, whereas reproductive cloning produces a cloned organism.

Reproductive cloning uses pluripotent cells, whereas therapeutic cloning does not.

Reproductive cloning uses embryonic stem cells, whereas therapeutic cloning does not.

Therapeutic cloning uses nuclei of adult cells transplanted into enucleated nonfertilized eggs.

A mutation that prevents the addition of the 5’cap would most likely have what effect?

Increase in transcription

Increase in gene expression

Reduction in gene expression

Reduction in transcription

Which is an example of epigenetic alteration?

Methylating the N-terminal tails of histones

Methylation of cytosines in the mRNA

Alternative splicing

Expressing miRNAs

What would happen if cytoplasmic determinants were distributed equally in a single-celled embryo before it divided?

There would be no gene expression in either of the daughter cells

Each daughter cell would receive a different subset of genes

Gene expression would be the same in the two daughter cells

Each daughter cell would express a different subset of genes

Answer 1

1). The difference between therapeutic cloning and reproductive cloning is that therapeutic cloning uses nuclei of adult cells transplanted into enucleated nonfertilized eggs.

2). A mutation that prevents the addition of the 5’cap would most likely have increase in transcription.

3). Methylating the N-terminal tails of histones  is an example of epigenetic alteration.

4). Each daughter cell would receive a different subset of genes when cytoplasmic determinants were distributed equally in a single-celled embryo before it divided.
