What are chromatids and how do they differ from chromosomes

Biology
1 answer:
Molodets [167]2 years ago
7 0
Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.

So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.

Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.

Hope this helps!

loris [4]

Answer:

Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.

Explanation:

Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.

bezimeni [28]

Answer: It shows the evolution of mutations. Throughout the lifetime of animals and humans depending on their way of life and how they life it they will slowly mutate into a different animal to be able to life that way..

Explanation: Example- Whales use to have legs and walked around the earth. But also loved to swim and play in water. Over time they began to adapt and mutate into what we know f whales now. With no legs, they have large fins to help them swim in the oceans.

A small family farm has 230 acres of farmland to grow corn . If each acre yields 63 bushels of corn and each bushel can be sold
SashulF [63]

Answer:

$130,410

Explanation:

According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn

Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00

If 1 bushel = $9.00

63 bushels = 63 × 9 = $567

Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.

Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year

Which is an extreme disturbance to any ecosystem ​
adelina 88 [10]
Extreme disturbances are complex events. The terminology used to identify them, such as 'hurricanes,' 'fires,' 'economic collapse,' 'war,' or 'drought,' is insufficient for advancing understanding about how they interact with, and affect, ecosystems, including SETS.
