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

Answer:

6 hours

Explanation:

after death every hour drops to 1.5 the temperature so if you multiply 6 * 1.5 it equals 9 and if you subtract that the 97.6 which is the average heat temperature of the adult then you will get 88.6 degrees which would be around your question

In a field of sunflower plants, 776 plants are tall and 224 plants are short. Sunflower height follows the normal pattern of inh
Nitella [24]

Answer:

The correct answer would be D) tt.

Recessive traits need a homozygous condition to get expressed and to produce a particular phenotype. In contrast, dominant trait can be expressed  in homozygous as well as heterozygous condition of the alleles of a gene.

Now, shortness is a recessive trait encoded by allele "t". Hence, allele "t" must be present in the homozygous condition in order to make the plant short.

Thus, the genotype of all the short plants in the field should be tt and the genotype of the tall plants would be TT or Tt.
