loris [4]4 years ago

Answer:

a, b, c are correct

Explanation:

Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.

Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.

Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.

There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.

Therefore, the correct options are (a), (b), and (c).

Describe the tissue stages of development. Include information on the embryonic germ layers and what they give rise to.
Vesnalui [34]

Answer:

Gastrulation takes place after cleavage and the formation of the blastula and the primitive streak. It is followed by organogenesis, when individual organs develop within the newly-formed germ layers. Each layer gives rise to specific tissues and organs in the developing embryo.Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs.

The DNA technology that is helping in this process is the CRISPR-Cas system.

<h3>What is the CRISPR-Cas system?</h3>

The CRISPR-Cas system is a genome editing tool that has revolutionized genetic and molecular biology.

This genome editing tool can be used to insert specific sequences of DNA into a chromosome and thus generate a new cell expressing of these genes.

In conclusion, The DNA technology referred here is CRISPR-Cas system.

If ssb is not present during dna replication, what would you expect to see?
In-s [12.5K]
A. SSB prevents reannealing of the separated strands, so strands would quickly reanneal and DNA replication cannot proceed.

Single-stranded binding proteins, or SSB, appear on the strands to separate the strands. Without a separation force, the strands would simply bind back together through hydrogen bonding.
