In a hemoglobin variant known as hemoglobin Kansas, an Asparaginein
IgorLugansk [536]

Answer:

The false statement is option a.

Explanation:

If there occurs a disruption of a hydrogen bond, which usually stabilizes the R-state of hemoglobin, there is not likely to be an elevation in the concentration of R-state due to the unsteadiness of the hydrogen bond. The R-state would either remain constant or will get slow down.  

Thus, the statement, that is, in hemoglobin Kansas, there is an elevation in the concentration of R-state and a reduction in the concentration of T-state is false.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here

ankoles [38]

Answer:

D. All of the above

Explanation:

Just as when we grow and need more food and energy so does a cell. when a cell is growing there is more of it that can be utilized putting more stress on the DNA to code whatever it needs. The bigger the cell is the denser and thicker the cell membrane gets making it harder for materials to work its way in and out of the cell.

Number of chromosomes in new cells meiosis
insens350 [35]

Answer:

23

Explanation: By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
