I think you're talking about histones. Histones are proteins found in eukayotic cell nuclei. Histones are what DNA wrap around so it fits inside the nucleus and helps with the formation of chromosomes.

How can carrying capacity in the ocean be best described?
KATRIN_1 [288]

<u>Answer</u>: c. Carrying capacity is the maximum population size required for a particular species in a particular area to survive.

<u>Explanation</u>: this is an average population density level. If the population density is above this level, the number of individuals will decrease. If the population density is under this level, the number of individuals will increase until the carrying capacity is reached once more.

Select all that are true. A short tandem repeat (STR):
Thepotemich [5.8K]

Answer:

C. Is a repeated sequence of DNA in a non- coding sequence

D. Can be composed of a variable number of repeats in different people

Explanation:

Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR <em>loci</em> which are used in forensic identity testing.

To determine whether the mutations in the seven strains leading to the wingless phenotype are in the same gene, your lab sets up
erik [133]

The question is incomplete as it lacks the question and has only information regarding the question. however, the correct question is as follows :

How many different genes are contributing to the wingless phenotypes in these mutant fly strains?

Answer:

The correct answer is - Two genes.

Explanation:

In the given question there are  two mutation groups based on the given seven results:

1st group :

Mutations 1, complement with 2,4, and 7  and also complement each other, thus, are on the same gene.

2nd group:

Mutations 3, 5, and 6 did not complement each other but complemented with mutations 1, 2, 4, and 7. Thus, these three mutations are present together on a different gene.
