A template dna strand contains the sequence 3'-atgctgac-5'. the corresponding sequence in the rna transcript is:
V125BC [204]
The corresponding sequence in the RNA transcript is 5'-UACGACUG-3' . One of the differences between DNA and RNA is the fact that the RNA contains the base uracil instead of thyamine. The base pairing occurs between A and T, and G and C. DNA undergoes the process of transcription in the nucleus to generate RNA, which then undergoes translation (for mRNA) in the cytoplasm to yield proteins.

A plant breeder has determined the following variances for yield of corn in his fields:
Law Incorporation [45]

Answer:

A. VG = 80

B. Broad sense heritability = 0.80

C. Narrow sense heritability = 0.30

D. Average yield = 430 Units

Explanation:

A. Given that

VA = 30

VD = 50

VI = assumed not available

Therefore

Total genetic variance (VG) = VA + VD

= 30 + 50

= 80

VG = 80

B. Given that

VP = 100

VG = 80

Broad sense heritability, H2 = VG/VP

= 80/100

= 0.80

C. Given that

VA = 30

VP = 100

Narrow sense heritability, h2 = VA/VP

=30/100

= 0.30

D. The difference in selection = 500 - 400

= 100

Recall,

Selection response is heritability multiplied by selection differential.

That is

R = h2S

Selection differential = 100

Heritability h2 = 0.30

Selection response = 0.30 × 100

= 30units

Therefore, expected average yield = 400 + 30

= 430 Units

An invasive species is an organism that’s not native to a particular ecosystem but ends up invading the region. The populations
denpristay [2]

An invasive species, such as the trees in your question, could:

- Out compete the native flora for resources, such as nutrients.

- An earlier reproductive and faster growing cycle could quickly surpass native tree growth.

- This alien species taking the place of native trees could disrupt the habitat of animal species that need the native flora instead.

Why would competition be considered a limiting factor within a ecosystem
raketka [301]

Answer

The main reason being the amount of food available.

Explanation:

Think of it this way:

If an animal is trying to find food but another species is looking for the same prey then its going to be increasingly difficult for the species to find prey and if there's not enough of the prey species then the population of the predator to go down.

That is why its considered a limiting factor.

What is shown in the imagine <br> prokaryote<br> eukaryote<br> chloroplast<br> mitochondrion
m_a_m_a [10]

"Prokaryote" is shown in the given image.

Answer: Option A

<u>Explanation:</u>

A prokaryote is a single-cell organism which is deficient in a membranous nucleus, mitochondria, or any other membranous organs. Prokaryotes are categorized into two domains: Bacteria and Archaea. At the third domain: Eukaryota, species with nuclei and organelles are located.

The asexual prokaryotes reproduce without fusion of gametes. They are considered as first living organisms. In the prokaryotes components like proteins, DNA and metabolites, overall the intra-cellular water-soluble components are enclosed by the cell membrane as situated together in the cytoplasm, rather than in separate cellular compartments.
