protein-coding gene

The genetic code is stored in the DNA of a cell. it is copied during the process of replication. An enzyme called helicase unwinds the double strand helix of DNA by breaking the hydrogen bonds that hold the two strands together, thus separating forming what is called replication fork. Next the enzyme DNA polymerase uses the single strands as a template and makes a new DNA strand by copying the template.

If an enzyme is absent during polypeptide production, what can occur? a mutation polymerization replication gene flow

Answers

The correct answer is mutation.

Any slight change in protein synthesis leads to the process of mutation. The polypeptide production here refers to the phenomenon of protein synthesis.

If an enzyme is absent during this process it lead to production of faulty protein or some other protein but exactly the same protein is not formed which could have formed when the enzyme would have been present.

This leads to mutation.

Sponges have flagellated cells called _____ that line their internal chambers and create water flow to capture food

Answers

choanocytes - spelling might be off on that... it means collared cells from Latin roots.

Answer:

Choanocytes

Explanation:

Choanocytes are membranous flagellate cells lining the spongiocelium (central body cavity of Porifera kingdom animals) and other internal vibrating chambers of sponges.

The movement of its flagellacreates the water stream that brings nutrients and gases. The nutrients are filtered by the choanocyte, which is not a solid structure, but rather a set of small erect rods separated by spaces.

Any organic particle or plant microorganism trapped in the choanocyte is routed down toward the cell body and endocyted, with intracellular digestion occurring in digestive vacuoles.

I am pretty sure that I have got the right answer because I've just seen 100% correct done quiz. So,the following which correctly describes a Lewis dot diagram for carbon is the third option from the scale represented above. C with one dot on the right side of the C and three dots on the left side of the C. I do hope you still need it because this one is really helpful.

Answer:

C with one dot on each of the four sides of the C

Explanation:

I just took the quiz this is correct

The wild-type coat color, agouti (AA) is dominant to solid-colored fur (aa). However, a separate gene C, when present as the recessive homozygote (cc), negates any expression of pigment from the A gene and results in an albino mouse. Therefore, the genotypes AAcc, Aacc, and aacc all produce the same albino phenotype. A cross between heterozygotes for both genes (AaCc x AaCc) would generate offspring with a phenotypic ratio of 9 agouti:3 black:4 albino. Which type of gene interaction is thisa. Complementary gene interaction.b. Duplicate gene interaction.c. Recessive epistasis.

Answers

Answer:

This is an example of recessive epistasis.

Explanation:

Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

In recessive epistasis, the proportion is 9:3:4.
